ABSTRACT A large majority of studies on differentiation focus their attention on 
the historical development and/or institutional designs of closer or enhanced 
cooperation in the EU, neglecting similar developments in other regions, for 
example, the pathfinder in APEC. In comparing cooperation in the EU with the 
pathfinder in APEC, this article aims to discover conditions of development of 
differentiation and its impact on the integration as a whole, and to present a few 
theoretical insights gained from this comparison. This paper begins with a critical 
review of the literature on the differentiation development in Europe and Asia. 
Then, from the framework inspired from liberal intergovernmentalism, the author  
comparatively analyzes enhanced cooperation in the EU and the pathfinder in 
APEC, and as a conclusion, evaluate the probable contribution of this analysis to 
better understanding differentiation and the development of integration theory.

Introduction

Differentiation has become the focus among scholars of regional integration study 
since the second half of the 1990s. As it becomes increasingly difficult to reach a 
consensus between all of the members of an enlarging regional polity, differentiation 
has become an effective alternative to general integration as a method in which to 
unify neighboring countries. Nonetheless, a large majority of studies on 
differentiation focus their attention specifically on the historical development and/or 
institutional designs of closer or enhanced cooperation in the EU (European Union), 
neglecting similar developments in other regions, for example, the pathfinder in 
APEC (Asia Pacific Economic Cooperation). Few efforts have ever been made to 
compare these similar movements in different regions or theorize upon the 
differentiation process in general. Thus, the politics of differentiation is absent in the 
theoretical debates or comparative studies concerning transnational integration. In 
comparing cooperation in the EU with the pathfinder in APEC, this article aims to 
discover conditions of development of differentiation and its impact on the integration 
as a whole, and to present a few theoretical insights gained from this comparison. This 
paper begins with a critical review of the literature on the differentiation development 
in Europe and Asia, followed by a search for an appropriate framework of analysis 
inspired by integration theories. From this framework, I will comparatively analyze 
enhanced cooperation in the EU and the pathfinder in APEC, and as a conclusion, will 
evaluate the probable contribution of this analysis to better understanding 
differentiation, in particular, and the development of integration theory, in general.

Theoretical Debate and Framework of Analysis

Comparability between EU and APEC

Although both EU and APEC are regionally integrated entities, they do not share 
enough common features to employ the 'most similar systems design' (MSSD) in this 
comparison. They are both sui generis in world politics. Based upon the treaties and 
perhaps a constitution in the future, the EU is neither a state nor an IGO, but is 
qualified as "less than a federation, more than a regime".  Created in the aftermath of 
a common declaration of the twelve founding states in Camberra in 1989, APEC is 
"the only intergovernmental grouping in the world operating on the basis of 
non-binding commitments, open dialogue and equal respect for the views of all 
participants".  In the institutional design, EU has developed some state-like executive, 
legislative and judicial mechanisms to implement laws and policies while APEC 
maintains its intergovernmental structure, which is characterized by regular meetings 
at different governmental levels. Today some 18,000 Eurocrats work for the European 
Commission but less than fifty officials are employed in the secretariat of APEC in 
Singapore. While the Qualified Majority Vote (QMV) has become the general rule in 
the Council decision-making of the EU, consensus still reins at all the meetings in 
APEC. If the EU has established a constitutional order based upon the rule of law, 
APEC puts its emphasis on voluntarism, leaving member states full freedom to 
implement its decisions. If European integration has been in pursuit of polity-building 
since its foundation, APEC is limited to facilitating "economic growth, cooperation, 
trade and investment in the Asia-Pacific region".  Fisher's speech at Humboldt in 
2000 has rekindled the debate over whether the European integration is leading 
toward the creation of a federation, while the vulnerability of APEC in the aftermath 
of the financial crisis in 1997 gave rise to discussions of whether its funeral had 
started or whether it had been rendered irrelevant by the 'ASEAN plus' projects. 
These institutional and political dissimilarities seem to encourage the 'most 
different systems design' (MDSD) in a comparison of EU and APEC. This design 
"compares countries that do not share any common features apart from the political 
outcome to be explained and one or two of the explanatory factors seen to be 
important for that outcome".  Both EU and APEC, argues Kahler, are "hard regional 
integration that is fostered and furthered by conscious political design", which is 
different from 'soft' regional integration that "is accomplished from the bottom up by 
the decisions of private investors, traders, and migrating workers."  Langhammer 
compares the free circulation of industrial products in the EU and APEC, concluding 
that the disadvantages of liberalization characteristic of the APEC style lie in the 
distortions between sectors and member states due to "rising disparities in timing 
liberalization".  Denman concludes that the current globalizing efforts to establish 
regionalized free trade zones in the EU and APEC "have led to processes of 
internationalization in which national governments, higher education institutions, and 
other international university organizations vie for position".  Based upon their 
quantitative analyses, Wei and Frankel insist that both the EU and APEC are 
contributive to global free trade.  Comparing APEC and the new Transatlantic 
Economic Partnership (TEP) initiated by the EU in 1996, an Australian scholar 
concludes that open regionalism will dominate the inter-regional cooperative 
arrangements.  In Europe, argues Chu, parameters in the EU exist between 
supranational and intergovernmental integrations, while in Asia, this parameter exists 
mainly within multi-integrations at different levels.  Comparing the 
security-economics nexus in Europe and East Asia, a Japanese scholar believes that 
the real challenge to regional integration comes when economic interdependence is 
stretched out into the security field, which, in turn, threatens the original 
security-economics framework.  Consequently the MDSD will be employed in the 
comparison of differentiation in EU and APEC in order to focus on this similar 
political outcome and the explanatory factors "seen to be important for that 
outcome".  

Categorization of sub-integrations

Sub-integration refers to an integration that occurs among some but not all members 
of an already existing integration. According to the objectives it pursues and the 
institutional framework it employs, sub-integration can occur within four categories 
as follows. (Table 1)

integration

Opt-out integration is a sub-integration in pursuit of the same objective as the larger 
integration but which occurs outside of the latter's institutional framework. The 
history of Shengen Agreement, signed June 1985, by France, Germany and Benelux, 
is an excellent example of opt-out integration. Considering the stubborn hostility from 
other member states in the EC - particularly the UK – to QMV extension, the five 
countries decided to sign an agreement outside of the EC but in an integrated pursuit 
of its objectives. They agreed to "gradually remove their common frontier controls 
and introduce freedom of movement for all individuals who were nationals of the 
signatory Member States, other Member States or third countries."  The entry into 
force of the Amsterdam Treaty legally and institutionally incorporated these Shengen 
acquis into the EU and EC with a protocol. This put an end to the opt-out integration, 
which has since then been transformed into a differentiated integration. Similar 
opt-out integration is happening among some members of APEC, which are planning 
to form a trade zone among all East Asian members of APEC while excluding Taiwan 
and Hong Kong. This "ASEAN plus three" (APT) project that began in 1997 aims to 
advance the free trade and particularly the promotion of economic and technical 
cooperation among its members, an objective of APEC many complain is too often 
neglected by its Anglo-Saxon member countries. Although the APT, like APEC, is 
not based on any treaty or formal binding agreement between participating states, and 
although it has no central secretariat, its "web of relations between the members has 
grown quickly since the first meeting of the heads of government in 1997."  Their 
finance, economics and foreign ministers, central bank governors and senior 
government officials in some domains have started meeting regularly since 1998.  
All of these meetings have taken place outside of APEC. 
Alienated integration is built up institutionally inside the larger integration but 
which curiously pursues other objectives than the ones imposed by the larger 
integration. The emerging European pillar inside NATO belongs to this kind of 
sub-integration. The original North Atlantic Treaty aims to deter any armed attack 
from the ex-Soviet Union by imposing Article five, which states that "an armed attack 
against one or more of them in Europe or North America shall be considered an attack 
against them all". However, the January 1994 NATO Brussels Summit endorsed the 
concept of the Combined Joint Task Forces, which provides for separable but not 
separate deployable headquarters that could be used for those European members-led 
operations. In June 1996, NATO foreign ministers agreed for the first time to build up 
a European Security and Defense Identity (ESDI) within NATO. They also decided to 
make NATO assets available for WEU (West European Union)-led crisis 
management operations, which is not among the original objectives of the North 
Atlantic Treaty.  
New integration occurs outside institutional frameworks and in pursuit of 
different objectives from the larger integration. However, such new integration is still 
related to the existing integration because its objectives and institutional mechanism 
both retain their influence on the existing one. It is therefore new but not novel. The 
Fouchet Project and Elysée Treaty in early 1960s are qualified as sub-integrations of 
this kind. The European Political Union Project designed by the French President De 
Gaulle adopted an intergovernmental cooperation approach with the hope of 
establishing regular meetings at all levels between member states. Furthermore, it was 
built up to coordinate or integrate economic, cultural, political and defense capacities 
between Germany, France, Italy and Benelux, deliberately outside of the then young 
European Communities. In the aftermath of failure of Fouchet Project, De Gaulle and 
Adenauer worked together for a bilateral close cooperation and signed the Elysée 
Treaty in January 1963. According to De Gaulle's original strategy, the Elysée Treaty 
should have served as the basis for a later six country-wide cooperative entity, leading 
to the establishment of the European Political Union that should dominate the existing 
Communities and reorient the European integration.  
Differentiated integration happens among some members of a larger integration 
and pursues objectives of and within the same institutional and legal frameworks of 
this larger integration. Both enhanced cooperation in the EU and pathfinder in APEC 
are qualified as differentiated integration owing to these institutional and teleological 
characteristics. In APEC, all the pathfinder initiatives must be "consistent with the 
Borgor Declaration" and "invigorate progress towards the Bogor Goals". In adopting 
the pathfinder initiatives, the APEC members must also respect "principles of 
voluntarism, comprehensiveness, consensus-based decision-making, flexibility, 
transparency, open regionalism and differentiated timetables for developed and 
developing economies".  In the same way, any enhanced cooperation in the EU must 
be "aimed at furthering the objectives of the Union and of the Community, at 
protection and serving their interests and at reinforcing their process of integration". 
(Article 43.a TEU) It also has to "respect the single institutional framework of the 
Union". (Article 43.b TEU) Such teleological and institutional conditions are 
presented to prevent a successful differentiated integration from dividing or 
destroying the larger integration, thus establishing a positive correlation between the 
sub-integration and the larger integration.

Key issues and framework of analysis

In order to establish such a correlation, two key issues must be addressed. First, when 
and under what circumstances will the differentiated integration be initiated, accepted 
and then implemented? Second, how and under what circumstances can a successful 
differentiated integration contribute to the progress of its larger integration as a 
whole?
The whole process of differentiation can be divided into four periods, including 
its ideation, initiation, adoption and implementation. As the differentiated integration 
must result from intergovernmental negotiations, the member governments or leaders 
without doubt play a dominant role in this process as liberal intergovernmentalism (LI) 
argues. Although LI's rational assumption, economic determinism to a certain degree 
and negligence of non-static actors are fiercely criticized by other approaches, nobody 
denies the dominant role of member states in such a constitutive and structural change 
of regional integration.  "It would be folly to suggest that the member states do not 
play a central part in policy development within the European Union."  
Even the assumption that member states act as a unitary actor in this process is 
often the case in the differentiation process. "All the governments have redlines," 
admits a Belgian official from the COREPER, "which are well known to each other. 
For example, UK and Luxemburg will never agree to uniform taxation. We all know 
that."  "No Austrian government will give green light to the free movement of 
water," said an Austrian diplomat at the IGC, "which is our white gold."  
"Malaysia," said an official in the SOM (Senior Official Meeting) of APEC, "will 
never allow the free trade in APEC to destroy its car industry."  The assumption that 
a member state will act as a unitary actor shall be accepted in the following analysis 
until it is falsified. Only those interest group, local authority or ministerial 
bureaucracy that has focused on this issue and proved to have exercised their 
influence during formulation of policy preferences of member states shall be 
particularly analyzed.
However, LI's rationality of member states or their leaders are often bounded, as 
historical institutionalism and incrementalism argue. Both approaches suppose that 
governments quite often have unclear objectives and cannot predict all of the 
consequences of their decisions. In fact, they may drift into agreements without 
appreciating their potentially significant implications. They may also avoid making 
decisions, preferring instead to postpone them while waiting for their implementation 
and development. They are also often locked by their past decisions into a system 
where they find it increasingly difficult to reassert their authority.  Such an argument 
based upon bounded rationality necessitates the evaluation of factors other than 
simply member states in the whole process of differentiation. With reference to John 
Peterson's terms,  these non-static factors shall be divided into intra- and 
extra-systemic factors. The intra-systemic factors, as some institutionalists claim, 
shall include values, norms, rules, laws, decision-making processes and institutional 
mechanisms of the multi-national integration. The extra-systemic factors are the 
politico-economic context, which, while outside of multi-national integration, still has 
a significant impact.
These intra-systemic factors constitute another framework that helps analyze the 
impact of differentiation upon the integration as a whole. Together, Laffan groups  
these factors into regulatory, normative and cognitive pillars.  The normative pillar 
is composed of values and norms. The former indicates the moral dimension and 
fundamental objectives of the polity while norms "establish a framework for behavior; 
of how things should be done and what are the legitimate means to pursue certain 
ends".  These norms also help participants "turn to established or familiar patterns of 
behavior to attain their purposes".  The cognitive pillar consists of symbols and 
collective identity. The former is "constitutive of reality, connecting individuals to the 
social and political order, establishing orientations for interpreting the world around 
us". The latter indicates the characteristics of the newborn polity that also distinguish 
it from others, particularly from its constituent units. The regulatory pillar shall, 
following Scott and Laffan's logic, consist of legal acts and institutional design. Legal 
acts are tools that can only be mobilized with help of institutional mechanisms, both 
of which then decide the regulatory capacities of the multi-national polity.
The following first sub-section will proceed with analysis of the intra- and 
extra-systemic factors and intergovernmental interaction in the differentiation 
processes inside EU and APEC. Based upon the three-pillared institutionalism, the 
second sub-section will then analyze comparatively the probable impact of enhanced 
cooperation on the EU and that of pathfinder on the APEC. 
 
Enhanced Cooperation and Pathfinder

Development of the sub-integration

Ideation

In the ideation process, practices preceded ideas of differentiation both in the EU and 
APEC, which later entered into into policy thinking particularly in the aftermath of 
failure of other more ambitious sub-integration projects. Until the early 1990s, few 
political elite or scholars supplied quality analyses on differentiated integration in the 
EU. The idea of differentiation was revitalized by Delors and Mitterrand, however, in 
a larger landscape of which the then EC was only part. Deeply worried that a rapidly 
enlarged EC would suffer from institutional paralysis and budgetary constraint, Delors 
prevented Commission officials from working on the Austrian application throughout 
1990. At the same time, he advocated the idea of a 'Europe of concentric circles' of 
which the then EC was at the center moving toward a federal polity, and was 
surrounded by the coming EEA (European Economic Area) at the second circle and a 
vaguely defined third circle of CEECs (Central and Eastern European Countries).  
Mitterrand proposed the establishment of a European confederation to contain the 
rapidly unifying Germany, of which the then EC and ex-Soviet Union were two 
pillars. 
Nonetheless, de facto differentiation came into existence far earlier than these 
ideas. As early as 1986, France, Germany and Benelux signed Shengen agreement 
aiming to establish the free movement of people outside of the Single European Act. 
The failure of the French-inspired proposals of 'concentric Europe' in early 1990s and 
the entry into effect of the Shengen agreement and convention coincided with the 
Reflections on European Policy released by CDU/CSU in 1994, which triggered 
intensive debate over differentiated integration inside the EU.
The first formal idea of differentiation appeared in APEC in 1997 when 
American and Australian delegations proposed to establish the Early Voluntary 
Sectoral Liberalization (EVSL) at the Committee on Trade and Investment (CTI) 
meetings. The EVSL targeted important areas where participant member states 
promise to facilitate efficient reductions to trade barriers and to ultimately open 
markets. It is, however, not a proposal for sectoral liberalization but rather a proposal 
for liberalization by product. Nonetheless, owing to skepticism from Asian countries 
toward any liberalist proposal after the Asian financial crisis, the Kuala Lumpur 
Summit in 1998 decided only to refer the EVSL proposals to the WTO. The efforts to 
achieve the EVSL effectively collapsed. 
However, a de facto differentiation came into practice a little earlier. In 
November 1996, APEC's CTI agreed to set up the APEC Business Mobility Group 
(BMG) with Australia as the lead country,  which became operational in 1997.  
The BMG, consisted of senior immigration officers of all the member states, and had 
the objective of facilitating free movement of businesspersons between the member 
states of APEC. The BMG then proposed to develop the APEC Business Travel Card 
Scheme based upon the database maintained in Canberra by Australia's Department of 
Immigration and Multicultural and Indigenous Affairs with mandate from APEC. 
Participating member countries in this scheme shall agree to simplify short-term entry 
arrangements for businesspersons and skilled persons seeking temporary residence.  
They have also to develop transparent arrangements to allow for seamless cross 
border movement. In 1997 Korea, the Philippines and Australia began to implement 
the APEC Business Travel Card Scheme. At the end of 2004, 16 of the 21 APEC 
members had joined the program.  Similarly the failure of EVSL and the success of  
BMG's proposal coincided with the very first notion of an APEC pathfinder.

Initiation

The intensive debate over differentiation triggered by the CDU/CSU proposal resulted 
in numerous proposals on differentiated integration between 1994 and 1996-1997 IGC; 
these proposals may be grouped into three categories.  A 'multi-speed integration' is 
defined as the mode of differentiated integration in which the pursuit of common 
objectives is driven by a core group of member states which are both willing and able 
to pursue some policy areas further, leaving others to follow later. In other words, all 
member states pursue the same objectives but at different times. A 'variable geometry' 
is a mode of differentiated integration which admits to unattainable differences within 
the main integrative structure by allowing permanent or irreversible separation 
between a core of members and lesser developed or simply unwilling units. That is, 
differentiation will be permanent rather than temporary, leading inevitably to the 
existence of two or three Europe around a probable noyeau dûr. The third concept is 
'Europe à la Carte', where member states are free to pick-and-choose which policy 
area they would like to participate in, while at the same time holding only a minimum 
number of common objectives. After a series of bilateral contacts at different levels, 
French and German leaders seem to have opted for the idea of 'multi-speed 
integration' although French governments made it well known that they preferred to a 
'variable geometry' around Franco-German axis.  In December 1995, French and 
German leaders published a common letter to the EU presidency, announcing their 
determination to "introduce in the Treaty a disposition that permits states able and 
willing to develop between member states, based upon the existent experiences, 
enhanced cooperation inside the institutional frame of the EU". For "one partner's 
momentary difficulties to follow the progress shall not prevent the Union from 
moving forward or improving its capacities for action."  In November 1996, the 
French and German governments submitted a common proposal on differentiation at 
the IGC, which constituted the basis for negotiations among member states.
The failure of EVSL and particularly the financial crisis deterred APEC member 
states from furthering free trade even on the basis of differentiation. "Most East 
Asians feel that they were 'both let down and put upon by the West' in the crisis."  
East Asian leaders, particularly of those countries that are victims of the financial 
crisis, since then have become extremely cautious vis-à-vis any liberalist proposals in 
APEC, particularly those from their Western partners. "In particular after the financial 
crisis in 1997," said a Taiwanese official from SOM of APEC, "Malaysian 
governments opposed to all initiatives that aimed to advance free trade inside APEC. 
All these initiatives were perceived as Western neo-colonialism in Asia."  "There 
has been a lack," admitted an Australian official, "of enthusiasm for trade 
liberalization in East Asia since the currency crisis."  The crisis seems therefore to 
reorient the proposal on differentiation, which now focuses on the trade facilitation, 
leaving the issue of lifting trade barriers to rising bilateral- or multilateralism. Even 
the proposal for an Asian Monetary Fund submitted by Japan failed. Between 1998 
and 2002, four FTAs (Free Trade Agreement) were signed, fifteen were under 
negotiation, thirteen were under study and twelve were proposed among member 
countries of APEC. The majority of them occurred between its developed or newly 
industrialized members.  Most important, in February 2004, Australia and US signed 
a FTA (AUSFTA), which will eliminate tariffs on most industrial goods, remove 
significant agricultural barriers, reduce barriers to investment from the US and vice 
versa, and provide equal treatment for providers of services and establishes a 
long-term process to enable professional qualifications to be recognized in each 
economy.  Leaving the implementation of free trade to bilateral- and multilateralism, 
the Australian government, with support from the US, focused on trade facilitation 
based on the mode of the APEC Business Travel Card Scheme, which led directly to 
the pathfinder initiative at the CTI meetings in 2000. "The pathfinder approach has 
already worked well in delivering outcomes in APEC. The case of the APEC Business 
Travel Card is a good example." 

Adoption 

The real discussion on the Australian initiative took place at the CTI (Committee on 
Trade and Investment) and SOM in APEC between 2000 and 2001; however, it 
unfolded without substantive debate. Though a significant number of Asian countries 
did not like to see any proposal for further liberalization from their Western partners 
in the post-currency crisis period, "no Asian government would like to be seen as an 
obstacle on the way towards Bogor goals".  But favorable voices also disappeared at 
the meetings, as some Asian countries were reluctant to make clear their support, 
fearing that they would be perceived by their neighbors as blind followers of the 
US-Australia's axis. 
"The pathfinder initiative is totally in our national interests," said a high ranking official in 
Taipei, "but we could not speak out our support at the meetings. Chinese delegation was always 
watching our reaction to any proposal from US and Australia. Chinese are worried that we 
would profit of this Australia-US axis to strengthen our identity in APEC. In such a case, they 
will mobilize other Asian neighbors to oppose fiercely any proposal."  
As historical institutionalists and incrementalists argue, those who were skeptical 
about further liberalization have no clear objectives on this novel issue and cannot 
predict all the consequences of their decisions. They drifted into agreements without 
appreciating their potentially significant implications, preferring to postpone their real 
opposition while waiting for their implementation and development. The SOM in 
March 2001 formally endorsed the pathfinder initiative. In October 2001, the APEC 
summit adopted the Shanghai Accord. The accords officially established the 
pathfinder approach in which capable and willing countries can forge ahead with 
market opening measures even if other members are not ready to follow.
At the IGC 1996-1997, differentiation was a novel issue but totally out of the 
core debate among member states of the EU. The core issues related to the extension 
of the QMV and co-decision process, re-weighing of voting in the Council and 
resizing of the Commission vis-à-vis the coming eastward enlargement, incorporation 
of WEU into the EU and communitarization of the JHA even though a majority of 
governments had ambiguous objectives and the whole negotiation process took place 
in indirection to a certain degree.  The question of flexibility relates intensively to 
the extension of QMV, where the predictable British veto seemed to persuade those 
integration-minded countries led by France and Germany to exploit a new approach to 
advance the EU-building. "The Belgian government was among the pioneers of 
enhanced cooperation," said a Belgian official from Attichi, "for it searched for a new 
role and strategy to play inside a larger and more federal Europe."  Like on many 
other issues, member governments often agree to the 'grand idea' of flexibility 
without, however, detailing their exact positions during the negotiation process. It 
seems that they prefer to make clear only their 'red lines' on this novel issue while 
waiting for its implementation and later development. 
According to their official documents, France and Germany, while attached to 
the idea of differentiation, still avoid mentioning any ideas like 'two Europe' or 
'noyeau dûr' that are doubtlessly incompatible with paramount values like equality, 
non-discrimination or solidarity of the EU; Denmark has reiterated its exemptions on 
the EMU, defense, citizenship and JHA;  Holland, Luxembourg, Ireland, Finland 
and Sweden are not opposed to the 'multi-speed' mode, but refuse, however, to have 
any membership of different classes;  Greece prefers to adopt only some 'temporary 
transitional provisions';  and Belgium, Portugal and Italy insist upon the 
differentiation inside the institutional structure of the EU.  As for the British 
government, the Tory party insists on the 'Europe à la Carte', hesitating to enlarge the 
QMV, while the Labor government does not modify much its attitude towards 
flexibility but has softened its hostility to the extension of the QMV.  The IGC 
1996-1997 resulted in the legalization of differentiation and the establishment of its 
basic principles and its limits, postponing key conflicting points to later IGC or 
Council of Ministers meetings.

Implementation and development

After the adoption of 'closer cooperation' by the IGC in 1997, differentiation in the 
EU was addressed in two amendments at the IGC in Nice in 2000 and 
Convention-IGC in Brussels in 2002-2004. However, as of yet, no enhanced 
cooperation has been formally applied. Regarding the pathfinder in APEC, eight 
initiatives have been endorsed since its adoption and in 2004 the implementation 
process was substantively reformulated.
According to the Shanghai Accord, a pathfinder in APEC can be agreed upon if 
it: 
-	is 'consistent with the Bogor Declaration;
-	respects 'APEC principles of voluntarism, comprehensiveness, 
consensus-based decision-making, transparency, open regionalism and 
differentiated timetables for developed and developing economies';
-	'provide a framework to encourage broader participation through enhanced 
capacity building programs';
-	is 'transparent and open'.
The whole Accord does not, however, clarify the adoption process of pathfinder 
initiatives. Instead, according to later practices, they are all agreed at the annual APEC 
summit, based upon proposals submitted by Ministerial Meetings and SOM. The very 
first step takes place at the CTI meetings. 
"Any member country can submit a one or two-paged paper at the CTI meetings, mentioning 
their willing to start a pathfinder on a specific issue. Generally it will have got an explicit 
support from at least one other member country through bilateral contacts before presenting it 
openly at the meetings. In principle, no country opposes it and the chairperson announces its 
adoption, which will be transferred to SOM, Ministerial Meeting and the summit.
"If participation of the pathfinder initiative necessitates signature of treaties, like the case of 
Kyoto convention on customs procedure, the lead economy will forward the documents to sign, 
of which each member country keeps one copy, binding them all. As APEC is not a strictly 
defined IGO, neither formal signature nor official deposit is needed."  
Among the eight pathfinder initiatives that came into existence between 2002 
and 2004, six were presented by Australia, one by Singapore and one by the US. 
"The implementation process of pathfinders is similar to all the other policies of APEC. All 
participant member countries define their own individual action plans and report their progress 
annually at the CTI and SOM meetings, where the lead economies give a general review of this 
pathfinder.
"It depends much on the lead economy. Those Australia-initiated pathfinders developed rapidly, 
which attracted more member countries to join in. Australians have worked hard through bilateral 
or multi-lateral talks to implement those pathfinder initiated by them. On the contrary, the 
Singapore-proposed pathfinder on electronic certificate of origin remains paperwork. Nothing 
really happens since its establishment."   
As for the US-led pathfinder on digital economy, member countries of APEC 
did not reach a real consensus, particularly on the subject of intellectual property and 
the liberalization of e-products. The ministerial meeting at Las Cabos in October 2002 
endorses six pathfinders but only 'recommends' that the summit adopt the "Statement 
to Implement the APEC Policies on Trade and the Digital Economy" as a pathfinder. 
Similarly the later summit 'endorsed' all pathfinders other than the one on digital 
economy, which is only "adopted…as a pathfinder initiative".
In 2004, the APEC pathfinder experienced fundamental reforms, leading to its 
further institutionalization.  Before establishing a pathfinder initiative endorsed by 
the summit, member countries must first proceed with an 'interim pathfinder' for at 
least one year. A three country quorum is needed to launch an interim pathfinder, 
which can be endorsed by the CTI without being submitted to higher levels. The 
interim pathfinder will be reviewed on an annual basis by the CTI or appropriate 
working groups and could to become a pathfinder if:
-	more than 25% member countries participate in it from the very beginning. 
Among the 21 member countries, six are needed.
-	the lead economy develops a detailed proposal, elaborating the objectives, 
implementation and proposed outcomes.
Then the CTI will propose to SOM that the interim initiative be granted 
Pathfinder status. On the basis of advice from CTI or the relevant working group, 
SOM would decide whether to continue a Pathfinder in its current form, or invite the 
lead country to revise it to better fit members' views. If, after three years of its 
implementation, less than 50% of member countries participate in the pathfinder or 
there appears to be little prospect of membership increasing in the short-term, SOM 
might decide to terminate it. SOM, composed of directors general of Foreign 
Ministries from member countries, plays now a dominant role in the implementation 
process of differentiation.
 Through the end of 2004, eight pathfinders in APEC have been established.

The differentiation design in the EU evolved at the successive IGCs and ended 
with the adoption of a Constitution for the EU in June 2004. At the IGC 1996, which 
aimed to put an end to this partial cooperation outside the TEU and TEC, the 
enhanced cooperation was first established in the first and third pillars with the 
so-called emergency brake similar to the Luxembourg Compromise. The Treaty of 
Nice extended this cooperation to the CFSP, while the emergency brake was lifted in 
the first and third pillars. The Constitutional Treaty made a further step in lifting this 
brake in the field of CFSP (Art. III-325) and established the 'structured cooperation' 
in ESDP (Art. III-213).
Based upon the single institutional framework, enhanced cooperation shall be 
initiated and implemented inside the same EU/EC institutional structures. In the 
Community, any member state shall submit its request to the Commission, which will 
then forward its proposal to the Council. With regard to police and judicial 
cooperation in criminal matters, the Member States shall submit their demands either 
to the Commission or directly to the Council if they are ignored by the Commission. 
In both cases, the Council shall then act by QMV on a Commission's proposal or the  
Member States' initiative. If any member state requests that the matter be referred to 
the European Council, the Council can only act by QMV after the matter has been 
raised in the European Council (TEU Art. 40b and TEC Art. 11.2). In the area of the 
CFSP, member states that wish to establish an enhanced cooperation shall address a 
request directly to the Council. The request shall then be forwarded to the EP for 
information and to the Commission for reviewed opinions on the consistency between 
the request and EU policies. The Council then acts by QMV unless any member state 
intends to oppose its adoption. The Council then may act by QMV to refer this matter 
to the European Council, which shall make its decision unanimously (TEU Art. 23 
and 27c). Any member state can consequently issue a de facto veto at the Council and 
later at the European Council (TEU Art. 23 and 27c), thought not in matters 
concerning military or defense (TEU Art. 27b). Any member state that wishes to 
participate in the enhanced cooperation shall notify its intention to the Council and the 
Commission. In principle, within four months, the Council shall act by QMV if it 
concerns the CFSP or former JHA (TEU Art. 27e and 40b). In the Community field, 
the Commission instead of the Council will make the decision. (TEC Art. 11a). 
What kind of legal instruments will be employed to implement the enhanced 
cooperation? Title VII of the TEU allows the member states to participate in the 
enhanced cooperation to adopt 'acts and decisions' for such an implementation. 
According to Articles 27a.2 and 40.1 of TEU and Article11.3 of TEC, it means that all 
the legal instruments in each pillar of the EU shall be respectively employed to 
implement the enhanced cooperation. In the execution of enhanced cooperation in the 
EC, the ECJ shall have jurisdiction over all these acts. Such a jurisdiction is excluded 
from the enhanced cooperation in the field of the CFSP and becomes a conditional 
one on the subject of the former JHA. Article 35 of the TEU establishes a new 
jurisdiction which is purely voluntary as far as the member states are concerned. In 
the field of police and judicial cooperation in criminal matters, the ECJ has 
jurisdiction to the extent that a member state decides to accept that jurisdiction.  
This mechanism resulted from a compromise between France and Germany, which 
sought to institutionalize this partial integration, and others led by the UK, which tried 
their best to handicap its functioning.  As a result, enhanced cooperation has been 
legalized since 1998 but has not yet been 'operated'. 

Influence of the sub-integration

First started to avoid institutional stagnation or collapse of a multinational integration, 
differentiation challenges nonetheless the regional polity in all of its constitutive 
pillars.

Regulatory pillars

Both in EU and APEC, differentiation employs the same legal or pseudo-legal tools as 
those of general integration. All legal acts in the EU and soft law in APEC may be 
mobilized to implement enhanced cooperation or pathfinder initiatives. Consequently, 
all legal principles developed during the integration shall prevail in the differentiation 
process. For example, the legal or pseudo-legal acts adopted to implement the 
differentiation shall enjoy statuses such as supremacy, immediate applicability and 
direct effect in the EU and voluntarism and loyal applicability in APEC. Several legal 
or pseudo-legal sub-systems and some form of differentiation acquis that is integrated 
and superior to those in its matrix may be established inside the integration as a whole. 
So, how could these sub-systems and those non-participant member countries be 
legally bridged to the constitutive system?
In scenario one, law and rules resulting from differentiation are recognized as an 
integral part of its general legal structure that all newcomers must accept before their 
accession. As for those non-participant member countries, they enjoy total immunity 
and freedom to take part in some or all provisions of this acquis. Incorporation of 
Shengen acquis falls into this category. Scenario two obliges the ins and outs to reach 
such formal agreements that legally bridge the two camps of differentiation. The 
'European Monetary System (EMS)-bis' and 'Pact of Growth and Stability' adopted 
by European Council in Amsterdam in 1997 belongs to this kind of arrangement. In 
scenario three, all participant member countries issue an understanding, endorsed by 
all, at the moment of their accession to the differentiation; this statement of 
understanding makes clear their attitudes towards this differentiation as well as those 
non-participant member countries. For example, when Chile agreed to adhere to the 
pathfinder on the digital economy in 2003, it reiterated that no "separate and distinct" 
judicial systems will be hence established to curtail "trade in infringing and 
counterfeit goods using e-commerce". 
On the institutional issues, both EU and APEC insist upon a single framework, 
refusing any initiative to establish new institutions. However, several scenarios exist 
that differ in their tolerance for sub-institutionalization. Scenario A refuses any new 
structure, maintaining the same as for the whole integration. Under such a 
circumstance, all non-participant member countries can effectively influence the 
differentiation process through the same institutional structure. For example, all 
members of the EU institutions participate in the implementation of Shengen acquis. 
Scenario B accepts creation of some informal structures that organize participant 
member countries, but taking no step to legalize these structures or give them 
decision-making powers. The 'Euro 12' reunites all Ecofin ministers of Euroland - 
outside the Council of Ministers - to debate any policy relating to the single currency 
without, however, giving them the power to make a decision. Scenario C divides the 
implementation process into two periods after its establishment. All member countries 
participate in the deliberation but only those participant member countries can vote on 
the issue concerned; this scenario is illustrated well in the enhanced cooperation in the 
EU. Scenario D completely excludes the influence of participant member countries in 
the differentiation implementation. Though no sub-structure is established, the whole 
implementation process has a de facto exclusion for those staying outside of the 
structure. The implementation of pathfinder initiatives in APEC depends much on the 
willingness and capacity of lead economy to proceed through bilateral diplomacy, a 
network composed of bilateral cooperation around the lead economy appears, which 
exists totally outside of those non-participant member countries. The API system is 
installed in Camberra and the SPS e-certificate designed by Australian government is 
even registered as an intellectual property in WIPO, to which a non-participant has no 
access. Accordingly, scenario I-A inclines to prevent any regulatory diversification 
resulting from differentiation while scenario III-D leads to the creation of a regulatory 
sub-system quasi-independent from the regulatory regime of the general integration.

Normative pillars

Differentiation inevitably casts doubt on the values of equality and solidarity as well 
as the norm of consensus-building in the integration as a whole. The key issue here is 
how to justify enhanced cooperation in the context of the whole integration. 
"Non-participant member states [of enhanced cooperation]," said a British leading 
MEP, "would never be quite sure that their interests were being protected by the 
arrangements, and the suspicion of discrimination would be ever present."  
Above all, differentiation developed from the opt-out or de facto partial 
integration practices in both the EU and APEC. In the late 1980s, Great Britain was 
privileged not to sign the Social Protocol and, together with Denmark, not to 
implement the single currency. The pathfinder was initiated by Australia, taking 
lessons from its earlier ideas on the APEC Business Travel Card Scheme. All of these 
opt-outs or partial integration did not prove to destroy or deter the integration as a 
whole. Quite on the contrary, the single currency would never have been launched 
without those opt-outs in the EU  and the Kyoto convention would never have been 
effective among member countries of APEC without pathfinder initiatives. Following 
the same logic, the partial integration based upon enhanced cooperation or the 
pathfinder initiatives could contribute to a great deal to European or Asia-Pacific 
integration as well. More important, differentiation was formally incorporated into the 
existing integration in order to 'delegitimize' similar cooperation among member 
states outside the EU or APEC. Without enhanced cooperation or pathfinder initiatives, 
cooperation outside EU or APEC may grow strong enough to replace or threaten the 
structures of the existing integration. If the differentiation project is rejected, 
cooperation on defense outside the EU might come into existence among France, 
Germany, Belgium and Luxembourg. If APEC continues to stagnate owing to its 
consensual tradition, it might be surpassed in the near future by the 'ASEAN plus 
Three' as the leading force in regional integration. "Enhanced cooperation already 
exists outside the Treaties (Eurocorps, EUROFOR, EUROMARFOR, etc.), 
formalizing it would allow these initiatives to be brought into the Union".  For a 
majority of the member states, making flexibility or enhanced cooperation "within the 
Union's institutional system [is] more attractive than interstate cooperation outside the 
institutional system".  Enhanced cooperation aims therefore to save rather than 
destroy the European integration. 
Thirdly, like subsidiarity and open methods, differentiation was first created as a 
result of the new integration paradigm developed since the early 1990s in order to 
reconstruct the legitimacy of both EU and APEC. This new paradigm calls into doubt 
the uniform regulation model developed in the 1950s and 1960s and emphasizes its 
respect towards the diversity of the member states as well as their discretion to 
implement the regional polity.  According to this logic, an Italian delegate at the 
Constitutional Convention insists that enhanced cooperation should be extended to the 
ESDN. "[The EU] is too big and heterogeneous, especially in the light of its future 
enlargement. Only a minority of countries in such a large Europe will have the 
political will and the material means to take part in military actions".  In APEC, the 
financial crisis and the failure of EVSL project casts doubt onto the absolute 
consensual tradition. Threatened by the increasing regional integration projects from 
China and ASEAN as well as the multiplication of FTA among constituents of APEC, 
those APEC-minded member countries cannot help but exploit the new approach to 
achieve integration based on the structures of APEC. "Now, only Australia, Singapore 
and Korea are serious about APEC. Japan is half-half. For Taiwan, it is one of the rare 
international organizations of which it is a full member. They all are worried that 
APEC will be weakened or dematerialized." 
The behavioral code in pursuit of differentiation continues this justification effort. 
The first principle is equality without equity, similar to that in the design of weighted 
votes in the Council of EU. All member states can require initiating a differentiation 
among themselves if they are more than eight in the EU or three in APEC. 
Differentiation, once established, shall be open to all member countries at any time. 
Another important principle is solidarity. Although some member states can launch 
differentiation, they have to respect the competences, rights and obligations of those 
Member States which do not participate therein. Moreover, those participating in 
differentiation shall ensure that as many member countries as possible have been 
encouraged to take part. In other words, those participating in differentiation shall 
make some effort to help outsiders qualify to participate in partial integration 
programs. On the contrary, when participating member states adopt acts and decisions 
to implement differentiation, the non-participant member countries shall not impede 
the implementation thereof by the participating member states. Last but not least, all 
efforts to establish differentiation shall respect what the EU or APEC has achieved, 
that is, the acquis. Nonetheless, it shall not form part of the integration acquis that 
accession countries have to all accept.

Cognitive pillars

Will the differentiation create a separate identity with its own symbols, which in turn 
dominates the original integration and splits it?
Among the eight existing pathfinder initiatives of APEC, Australian government 
launched six out of eight pathfinder initiatives and a core group around Camberra 
appears to exist. (Table 5) Australia, Canada, New Zealand, US, Singapore, Taiwan 
and Korea seem to emerge as leading member countries in this differentiation process 
while China and ASEAN countries with exception of Singapore are in general 
excluded from this development. Regarding Japan, the leading economy in East Asia, 
it also seems to have lagged behind in the sub-integration competition.

Will this core group emerge as a solid sub-integration that threatens, damages or 
splits APEC? It seems not. Institutionally, like all forms of differentiation, it happens 
under the APEC structures and bound by solidarity-related clauses. Politically, all 
seven of these member countries have no interest in seeing APEC weakened or split 
into two integrations separately led by US-Australia in Pacific and China-ASEAN in 
East Asia.
In the EU, France, Germany, Benelux, Italy, Spain, Portugal, Greece and Austria 
all are members of Shengen area and Euroland. Ireland and Finland has adopted the 
euro as their currency while Sweden and Denmark participate in the free movement of 
persons. At the Convention and IGC from 2002 to 2004, French, German, Belgian and 
Luxembourg governments reiterated their decision to achieve cooperation on defense, 
which got support from UK and Italy. Will a sub-integration around the six founding 
member states develop into an avant-garde in the EU that grows so fast it will become 
a new integration outside of the existing structure? Such a possibility should not be 
totally excluded because it echoes well the famous 'Europe of three circles' proposed 
by French leaders between in 1994-1995.  "It is French dream to re-establish a 
Europe between the six without particularly the British participation," said a leading 
French historian, "which will permit once again France an opportunity to become a 
grande nation with support of a smaller Europe in the 21st century."  However, as 
differentiation is strictly contained in the EU structures and under surveillance of all 
political leaders as well as the public, it shall be quite difficult to constitute such a 
directoire based on any ideas of concentric Europe.
Regarding the public opinion, according to the most recent Eurobarometer, a 
majority of European Union citizens (61%) say "they rather agree with a proposal 
according to which the Member States that so wish could increase their cooperation 
without waiting for the others". In particular, unlike the situation observed for the 
other proposals, a firmer rate of acceptance for this proposal in countries that tend to 
be more 'Eurosceptical' like the United Kingdom (67%) or Poland (72%) is evident.  
"The British elite and people do not seriously fear that enhanced cooperation damage 
their core interests. For example, partial integration on taxation shall merely result in 
more foreign direct investment (FDI) fleeing to the UK." 
	Nonetheless, at the Constitutional Convention between 2002 and 2003, several 
representatives from CEECs did not hide their deep worries and fears that such 
flexibility will lead to a structured discrimination against small and late-coming 
member states in the EU. "A mechanism of solidarity with those remaining outside 
the enhanced cooperation," said Mr. Adrian Severin, MP from Romania, "should be 
guaranteed with the European Commission playing a stronger role as a mediator".  
According to the Bulgarian government, in the area of CFSP/ESDP, any member state 
seeking to protect its immediate national security should retain veto power.  "In the 
present situation of the European defense policy," said the Polish parliamentary 
representative, "it is too early to create some 'exclusive' forms of cooperation in the 
military matters." The Poles have serious doubts as to the concept of "structured 
cooperation in the military and defense affairs".  For them, openness and solidarity 
shall be basic principles of the enhanced cooperation while acquis as well as rights of 
those outside of it shall not be affected.  The British MEP, Mr. Duff, concluded the 
probable negative impacts upon the EU structures: 
"First and foremost, enhanced cooperation would rupture decision-making in the Council. But 
the collegiality of the Commission would also be under threat, and how MEPs would cope with 
being divided between the ins and outs is not self-evident. The Court of Justice would have to 
insist on the necessity of upholding the corpus of EU law, and would be wholly justified in 
fearing the development of two separate acquis." 

Conclusion

Political and institutional dissimilarities between the EU and APEC permit scholars to 
compare their nearly simultaneous sub-integrations since mid 1990s on the basis of 
MDSD. The categorization of sub-integrations makes it clear that enhanced 
cooperation and pathfinder both belong to differentiated integration that happens 
inside the same institutional framework with identical teleological settings as their 
matrix. From ideation to initiation, some prototyped practices preceded the proposals, 
which were officially presented only after some other more ambitious projects proved 
to be non-starters. The adoption process mainly depends on intergovernmental 
negotiations despite the fact that a majority of countries truly drifted into agreements 
without appreciating exactly their potentially significant implications while waiting 
for their implementation and development. Regarding new conceptions, member 
countries seem to prefer to hide their opposition or suspicion and usually do not adopt 
a categorical opposition. Compared to clear-cut issues and debate, their interests in 
new conceptions may be still vague. In particular, both differentiation in the EU and 
APEC generally have been established first with general principles, leaving the 
operational mechanism to be fixed later. Few countries prefer to veto it at this 
beginning moment.
Nonetheless, development of differentiation diverges in its implementation in the 
EU and APEC. As APEC has established eight pathfinder initiatives since 2002, the 
enhanced cooperation has never been utilized since the Treaty of Amsterdam entered 
into effect in 1998. Different from the EU, APEC first created a loosely structured 
framework for the pathfinder initiatives, which were then ceaselessly reviewed and 
modified. A more detailed mechanism was established in 2004, which divides the 
differentiation in APEC into three periods: interim pathfinder, formal pathfinder and 
review process. As the uniform regulation model is leaving, to be replaced by a new 
paradigm based upon its respect toward the diversity of its constituent units, open 
regionalism and soft law system developed by APEC is no less capable than the legal 
order created by the EU in facilitation the differentiation.
Enhanced cooperation and pathfinder also diverge in their impact on regional 
integration. Compared to the former, the latter is more inclined to develop a separate 
regulatory pillar inside APEC. A core group around Australia-US also seems to have 
appeared inside APEC, though no member of this core group finds any interest in 
seeing APEC split into an Asia dominated jointly by China-ASEAN and a Pacific led 
by Australia-US axis.
	The whole analysis also seems to have reconfirmed the values of LI in its 
comparison of differentiation in the EU and APEC. Though member states are not 
always the unique actors in these processes, they are without doubt the dominant ones. 
On the issue of differentiation, few regional, bureaucratic or supranational actors 
influence the process as much as leaders and governments of member countries. LI is 
particularly privileged in the comparative analyses of EU and other regional polities 
as the latter, quite often, is far less supranational or institutionalized as the former. LI 
therefore supplies a useful and flexible framework of analysis that permits scholars to 
compare similar developments between regional integrations around the world.
