European Union Enlargement

The European Union (EU) is an economic and political partnership that represents a unique form of cooperation among 28 member states today. The EU has long viewed the enlargement process as an historic opportunity to further the integration of the continent by peaceful means. Analysts contend that the carefully managed process of enlargement is one of the EU's most powerful policy tools and has helped transform former dictatorships such as Spain and many of the former communist states of Central and Eastern Europe into stable democracies and free market economies. The EU maintains that the enlargement door remains open to any European country, including Turkey and those of the Western Balkans, able to fulfill the EU's political and economic criteria for membership. Croatia is the newest member state, joining the EU on July 1, 2013.
At the same time, many observers assess that EU enlargement may soon be reaching its limits, both geographically and in terms of public enthusiasm for further expansion. Some suggest that the EU's financial troubles could impede the EU's remaining enlargement agenda if EU leaders remain preoccupied with internal EU issues. Others point out that the EU's economic woes and increased uncertainty about the future direction of the EU itself might make joining the Union less attractive for some current and potential EU candidates.

	Evolution of the European Union

The EU is the latest stage in a process of European integration aimed at promoting political reconciliation and economic prosperity throughout the European continent. It has been built over several decades through a series of binding treaties.

		Origins

After World War II, leaders in Western Europe were anxious to secure long-term peace and stability in Europe and to create a favorable environment for economic growth and recovery. In 1952, six states—Belgium, the Federal Republic of Germany, France, Italy, Luxembourg, and the Netherlands—established the European Coal and Steel Community (ECSC), a single market in these two industrial sectors controlled by an independent supranational authority. In embarking on this integration project, its founders hoped that the ECSC would help control the raw materials of war and promote economic interdependence, thus making another conflict in Europe unthinkable.
In 1957, the six ECSC member states signed two new treaties in Rome: the first established the European Economic Community (EEC) to develop common economic policies and merge the separate national markets into a single market in which goods, people, capital, and services could move freely; the second created a European Atomic Energy Community (EURATOM) to ensure the use of nuclear energy for peaceful purposes. These two treaties, commonly referred to as the "Treaties of Rome," came into force in 1958. In 1967, the ECSC, the EEC, and EURATOM collectively became known as the European Community (EC).
The EC first added new members in 1973, with the entry of the United Kingdom, Ireland, and Denmark. Greece joined in 1981, followed by Spain and Portugal in 1986. The Single European Act modified the EC treaties in 1987 to facilitate the creation of the single market, introduced institutional reforms, and increased the powers of the fledgling European Parliament. At the beginning of 1993, the near completion of the single market brought about the mostly free movement of goods, people, capital, and services within the EC.

		Birth of the EU

On November 1, 1993, the Treaty on European Union (also known as the Maastricht Treaty) went into effect, establishing the modern-day European Union and encompassing the EC. The Maastricht Treaty established an EU consisting of three pillars: an expanded and strengthened EC; a common foreign and security policy; and common internal security measures. The Maastricht Treaty also contained provisions that resulted in the creation of an Economic and Monetary Union (EMU), including a common European currency (the euro). The European Union was intended as a significant step on the path toward not only greater economic integration but also closer political cooperation.
On January 1, 1995, Austria, Finland, and Sweden joined the EU, bringing membership to 15 member states. In June 1997, EU leaders met to review the Maastricht Treaty and consider the future course of European integration. The resulting Amsterdam Treaty, which took effect in 1999, enhanced the legislative powers of the European Parliament, sought to strengthen the EU's foreign policy, and aimed to further integrate internal security policies.
In December 2000, EU leaders concluded the Nice Treaty to pave the way for further EU enlargement, primarily to Europe's east. Entering into force in 2003, the Nice Treaty set out internal, institutional reforms to enable the Union to accept new members and still be able to operate effectively. In particular, it extended the majority voting system in the EU's Council of Ministers (representing the member states) to a number of additional policy areas that had previously required unanimity, and restructured the European Commission (the EU's executive).

		From 15 to 28

Since the end of the Cold War, the EU had worked with the former communist countries of Central and Eastern Europe to reform their political systems and economies in order to meet the EU's membership criteria. The EU viewed enlargement to Europe's east as fulfilling a historic pledge to further the integration of the continent by peaceful means, overcome decades of artificial division, and help make Europe "whole and free." Cyprus and Malta had also expressed interest in joining the EU. In March 1998, the EU began accession negotiations with Cyprus, the Czech Republic, Estonia, Hungary, Poland, and Slovenia. In December 1999, the EU decided to open negotiations with six others: Bulgaria, Latvia, Lithuania, Malta, Romania, and Slovakia.
In December 2001, the EU announced that 10 of these countries—Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia—would likely be able to conclude accession talks by the end of 2002. Negotiations in 2002 with these 10 candidates on remaining issues such as agriculture and regional assistance proved challenging because they raised budgetary and burden-sharing issues. A deal was finally reached, however, and the EU concluded accession talks with all 10 at its December 2002 summit. The accession treaty was signed with the 10 countries on April 16, 2003, and they acceded to the EU on May 1, 2004.
In December 2004, the EU completed accession negotiations with Bulgaria and Romania, despite some continued EU concerns about the status of judicial reforms and anti-corruption efforts in both countries. Bulgaria and Romania formally joined the EU on January 1, 2007. Croatia acceded on July 1, 2013, bringing the Union to 28 member states. The Union's borders now stretch from the Baltics to the Black Sea, and the EU has a total population of over 500 million.

		Further EU Institutional Reforms and Enlargement

Although the Nice Treaty had sought to introduce institutional reforms to allow an enlarged Union to function better and more effectively, critics asserted that the treaty established an even more complex and less efficient decision-making process. Certain provisions in the Nice Treaty also effectively (although not explicitly) limited the size of the EU to 27 member states. In light of the criticisms of the Nice Treaty and with a view to potential enlargement beyond 27 members, the EU embarked on a new institutional reform effort in 2002.
This process culminated on December 1, 2009, when the Lisbon Treaty came into force. The Lisbon Treaty evolved from the proposed EU constitutional treaty, which was rejected in French and Dutch national referendums in 2005, in part because of public concerns about continued EU enlargement. The Lisbon Treaty aims to further streamline the EU's governing institutions and decision-making processes, and in doing so eliminates the technical hurdle to enlarging the EU beyond 27 member states. The new treaty also seeks to give the EU a stronger and more coherent voice and identity on the world stage, and attempts to increase democracy and transparency within the EU, in part by granting more powers to the European Parliament.

	Process of Enlargement

According to the Maastricht Treaty, any European country may apply for EU membership if it meets a set of core political and economic criteria, known as the "Copenhagen criteria." These criteria for EU membership require candidates to achieve "stability of institutions guaranteeing democracy, the rule of law, human rights and respect for and protection of minorities; a functioning market economy, as well as the capacity to cope with competitive pressure and market forces within the Union; the ability to take on the obligations of membership, including adherence to the aims of political, economic, and monetary union." In addition, the EU must be able to absorb new members, so the EU can decide when it is ready to accept a new member.
When a country submits an application to join the EU, it triggers a complex technical process and a sequence of evaluation procedures. At the same time, EU enlargement is very much a political process; most all steps on the path to accession require the unanimous agreement of the existing member states. As such, a prospective EU candidate's relationship or conflicts with individual member states may significantly influence a country's EU accession prospects and timeline.
Following the submission of a given country's application, the European Commission first issues a formal opinion on the aspirant country, after which the Council of Ministers decides whether to accept the application. Following a positive unanimous decision by all 28 member states in the Council of Ministers to accept a given country's application, that country becomes an official EU candidate. Accession negotiations, a long and complex process in which the candidate country must adopt and implement a massive body of EU treaties, laws, and regulations, may then begin. The Commission and the Council of Ministers (acting unanimously) must also approve the actual opening of accession negotiations and a negotiating framework, which establishes the general guidelines for the enlargement talks.
The EU's nearly 144,000 pages of rules and regulations are known as the acquis communautaire . The acquis is divided into 35 subject-related "chapters" that range from free movement of goods to agriculture to competition. Accession negotiations on each chapter begin with a screening process to see to what extent the applicant meets the requirements of each chapter; detailed negotiations take place at the ministerial level to establish the terms under which applicants will adopt and implement the rules in each chapter. The European Commission proposes common negotiating positions for the EU on each chapter, and conducts the negotiations on behalf of the EU. Enlargement policy and accession negotiations are directed and led by the EU Commissioner for Enlargement and European Neighborhood Policy, currently Stefan Füle.
In all areas of the acquis , the candidate country must bring its institutions, management capacity, and administrative and judicial systems up to EU standards, both at national and regional levels. During negotiations, applicants may request transition periods for complying with certain EU rules. All candidate countries receive financial assistance from the EU, mainly to aid in the accession process.
Chapters of the acquis can only be opened and closed with the unanimous approval of all 28 existing EU member states acting in the Council of Ministers. Periodically, the Commission issues "progress" reports to the Council of Ministers and the European Parliament assessing the achievements in the candidate countries. Once the Commission concludes negotiations on all 35 chapters with an applicant state, the agreements reached are incorporated into a draft accession treaty, which must be approved by the Council of Ministers and the European Parliament. After the accession treaty is signed by the EU and the candidate country, it must then be ratified by each EU member state and the candidate country; this process can take up to two years.

	Current EU Candidates

Currently, five countries are considered by the EU as official candidates for membership: Iceland, Macedonia, Montenegro, Serbia, and Turkey. All are at different stages of the accession process, and face various issues and challenges on the road to EU membership.

		Iceland

Iceland has close and extensive ties with the EU. Iceland and the EU have a free trade agreement dating back to 1972, and Iceland has been a member of the European Economic Area (EEA) since 1994. Through the EEA, Iceland participates in the EU's single market, and a significant number of EU laws already apply in Iceland. Iceland also belongs to the Schengen area, which enables Icelanders to work and travel freely throughout the EU, and participates in a number of EU agencies and programs in areas such as enterprise, the environment, education, and research.
In July 2009, the former pro-European socialist-green coalition government submitted Iceland's application for EU membership in the wake of the 2008 financial crisis that led to the collapse of Iceland's banking system and the devaluation of its national currency. Despite divisions among Iceland's political parties and doubts among many Icelandic citizens about the benefits of EU accession, the government believed that membership would bolster Iceland's ability to recover from economic recession. The EU named Iceland as an official candidate in June 2010, and began accession negotiations with Iceland in July 2010. Given Iceland's existing integration with the EU, many observers expected accession talks to proceed quickly. As of the end of 2012, talks had been opened on 27 of the 35 negotiating chapters, and 11 had been provisionally closed.
Iceland's accession negotiations, however, have been on hold since May 2013, following the election of a new center-right coalition government largely opposed to EU membership. The EU continues to consider Iceland an official candidate country, but at present, Iceland's future EU prospects appear doubtful. Upon assuming office, the new Icelandic government announced that it would hold a public referendum on whether Iceland should resume EU accession negotiations. In February 2013, a government-commissioned report on Iceland's relations with the EU was presented to the Icelandic parliament, but no date has been set for the referendum. Opinion polls suggest a strong "no" camp exists in Iceland on EU membership, especially as Iceland's economy continues to improve. Even if Iceland were to resume accession negotiations at some point in the future, several challenges would remain. These include resolving differences with the EU on fisheries and whaling policies, and settling an ongoing dispute over fully repaying the British and Dutch governments for debts incurred when Iceland's online bank—Icesave—failed in 2008.

		Macedonia

Macedonia is one of the six countries that made up the former Yugoslavia. Within a decade of gaining independence, Macedonia concluded a Stabilization and Association Agreement (SAA) with the EU in 2001 to govern relations. It applied for EU membership in March 2004. The EU named Macedonia as an official EU candidate in December 2005.
The European Commission has recommended opening membership talks with Macedonia since 2009. According to the Commission, Macedonia is sufficiently fulfilling the political and economic criteria for membership, although EU officials have expressed some concerns about the country's democratic progress following its political crisis in late 2012-early 2013 and the government's treatment of journalists and the media. The EU continues to urge Macedonia to complete necessary reforms aimed at improving the rule of law, protecting freedom of expression, promoting the independence of the judiciary, and strengthening anti-corruption efforts. Some EU officials also remain concerned about inter-ethnic tensions in Macedonia, especially with respect to its Albanian minority.
Macedonia has not yet secured a start date for accession negotiations. For years, this has been due largely to a long-running disagreement with Greece over the country's official name. Macedonia maintains the right to be recognized internationally by its constitutional name, the Republic of Macedonia, but Greece asserts that it implies territorial claims to the northernmost Greek province of the same name. Presently, the EU refers to Macedonia in official documents as the Former Yugoslav Republic of Macedonia (FYROM), a provisional name coined in 1993 to enable Macedonia to join the United Nations.
As a result of the name dispute, Greece continues to block the opening of EU accession talks with Macedonia. Bulgaria has also raised concerns about Macedonia's readiness for EU membership amid growing tensions between the two countries. In light of Macedonia's recent political difficulties and what some view as deteriorating democratic standards in the country, several other EU member states now appear reluctant to support opening accession negotiations as well, at least in the short term.
Given the ongoing stalemate in Macedonia's accession bid, the European Commission launched a High Level Accession Dialogue (HLAD) with Macedonia in March 2012 in order to help maintain momentum for political and economic reforms in the country. EU officials contend that the HLAD has contributed to progress in most priority areas, including the elimination of court backlogs and the fight against corruption. However, the Commission and a number of outside experts warn that as long as Macedonia's formal accession process remains stalled, it could put the sustainability of the country's reform efforts at risk.

		Montenegro

After ending its union with Serbia and gaining independence in June 2006, Montenegro and the EU began talks on a Stabilization and Association Agreement. The SAA was signed in October 2007. Macedonia applied for EU membership in December 2008 and was granted candidate status in December 2010.
In October 2011, the European Commission assessed that Montenegro had achieved the necessary degree of compliance with the political and economic criteria for accession talks to begin. The EU opened accession negotiations with Montenegro in June 2012. As of December 2013, seven negotiating chapters had been opened, and two of these provisionally closed. EU officials acknowledge Montenegro's solid progress toward meeting EU standards, but they also assert that more work is needed. Key challenges facing Montenegro include improving the rule of law, fighting corruption and organized crime, enhancing the independence of the judiciary, guaranteeing freedom of expression, strengthening administrative capacity, and improving the business environment.

		Serbia

Until relatively recently, Serbian-EU relations were difficult and Serbia's path toward eventual EU membership faced several obstacles. Most EU member states and EU officials viewed Serbia as bearing the bulk of responsibility for the violent dissolution of the former Yugoslavia in the 1990s and for the 1999 conflict over its former province of Kosovo. Many in the EU considered Serbia as being slow to implement necessary political and economic reforms, largely uncooperative in tracking down Serbian war crimes suspects indicted by the International Criminal Tribunal for the former Yugoslavia, and resistant to normalizing relations with Kosovo (which declared independence from Serbia in 2008, but which is not recognized by Serbia).
Over the last few years, however, Serbia has made considerable progress in modernizing its political and economic system. As part of EU efforts to boost pro-Western political forces in the country, the EU concluded a Stabilization and Association Agreement with Serbia in April 2008. In December 2009, Serbia submitted its formal application for EU membership. In the summer of 2011, Serbia's accession prospects improved significantly following the arrest and extradition of two high-profile war crimes suspects wanted by the International Criminal Tribunal for the former Yugoslavia.
In October 2011, the European Commission recommended EU candidate status for Serbia, provided that it continued to work on improving relations with Kosovo in EU-brokered talks. In February 2012, Serbia concluded two accords with Kosovo aimed at addressing some key EU concerns; Serbia agreed to conditions under which Kosovo may participate in Western Balkans regional institutions, and on the technical parameters for jointly managing its border with Kosovo. In light of these accords, the EU named Serbia as an official candidate in March 2012. Talks between Serbia and Kosovo continued under EU auspices.
In December 2012, EU leaders agreed to assess the possibility of opening negotiations with Serbia in spring 2013, following a Commission report on Serbia's progress toward meeting all EU membership criteria, and especially on whether Serbia had done enough to enhance its relations with Kosovo. In April 2013, Serbia and Kosovo reached a landmark agreement on normalizing relations, aimed in particular at resolving the situation in Northern Kosovo, which is mostly ethnic Serbian and over which Belgrade has exercised de facto control. In June 2013, the EU announced it would open accession negotiations with Serbia by January 2014 at the latest. EU governments wanted some additional time to assess progress on the implementation of the Serbia-Kosovo agreement before fixing a firm start date for launching the accession talks.
In December 2013, EU member states endorsed opening accession talks with Serbia, and the first negotiating session took place in late January 2014. In doing so, the EU noted that "Serbia has achieved the necessary degree of compliance with the membership criteria, and notably the key priority of taking steps towards a visible and sustainable improvement of relations with Kososvo." The EU also urged Serbia to continue its efforts toward improving the rule of law, reforming the judiciary, fighting corruption and organized crime, protecting minority rights and media freedoms, and enhancing its business environment. At the same time, Serbia will not be ready to join the EU for many years (Serbian officials suggest that it would likely not be until 2020 at the earliest), and some experts assert that ultimately, the EU may not admit Serbia as a member until Kosovo's independence status is fully resolved.

		Turkey11

Turkey has a long-standing bid for EU membership, but the relationship between Turkey and the European project has been characterized historically by a series of ups and downs. Although EU member states have always supported a close association with Turkey, divisions continue to exist among member states over whether Turkey should be allowed to join the Union given concerns about its political system, human rights record, economy, and large Muslim population. The status of Turkey's membership application is a frequent source of tension between Turkey and the EU.
Turkish EU aspirations date back to the 1960s. Turkey and the European Economic Community concluded an association agreement (known as the Ankara Agreement) in 1963, which was aimed at developing closer economic ties. The Ankara Agreement was supplemented by an Additional Protocol, signed in 1970, preparing the way for a customs union. Nevertheless, Turkey's 1987 application for full membership in the European Community was essentially rejected.
In 1995, the customs union between the EU and Turkey entered into force, allowing most goods to cross the border in both directions without customs restrictions. In 1997, the EU declared Turkey eligible to become a member of the Union. In 1999, the EU finally recognized Turkey as an official candidate country; at the same time, the EU asserted that Turkey still needed to comply fully with the political and economic criteria for membership before accession talks could begin.
In 2001, the EU adopted its first "Accession Partnership" with Turkey, setting out the political and economic priorities Turkey needed to address in order to adopt and implement EU standards and legislation. Ankara had hoped that the EU would set a firm date for starting negotiations at its December 2002 summit, but was disappointed; several EU members argued that although Turkey had undertaken significant reforms—such as abolishing the death penalty and increasing civilian control of the military—it still did not fully meet the membership criteria. Some member states also remained concerned about Turkey's stance toward Cyprus, which has been divided since 1974 between the internationally recognized Republic of Cyprus administered by the Greek Cypriot government in the island's south, and the Turkish Republic of Northern Cyprus, controlled by Turkish Cypriots. Turkish troops remain stationed in northern Cyprus, and Turkey does not recognize the Republic of Cyprus under the Greek Cypriot government.
In December 2004, the EU asserted that Turkey had made sufficient progress on legislative, judicial, and economic reforms to allow accession talks to begin in October 2005, provided that Turkey met two conditions by that time: bringing into force several additional pieces of reform legislation; and agreeing to extend Turkey's existing agreements with the EU and its customs union to the new EU member states, including Cyprus. Turkey met both of these requirements by July 2005. In pledging to extend its EU agreements and the customs union, however, Turkey asserted that it was not granting diplomatic recognition to the Greek Cypriot government. After some contentious debate among EU members over issues related to Turkey's lack of formal recognition of Cyprus and whether a "privileged partnership" short of full membership for Turkey should be retained as a future option, the EU opened accession talks with Turkey in October 2005. The EU asserted that the "shared objective of the negotiations is accession," but that it will be an "open-ended process, the outcome of which cannot be guaranteed beforehand." In other words, Turkey is still not ensured eventual full EU membership.
Detailed negotiations between the EU and Turkey on the acquis began in 2006. Since then, the EU has opened talks on 14 chapters of the acquis (one of these was provisionally closed in June 2006), but progress has been slow and complicated in part by Cyprus-related issues. According to the EU, Turkey's continued refusal to open its ports and airports to ships and planes from the Greek Cypriot part of the island, as required by the 1970 Additional Protocol and the customs union, is a major stumbling block. In December 2006, the EU decided to delay the opening of eight chapters dealing with areas affecting the customs union pending Turkey's compliance with applying the Additional Protocol to Cyprus. Although negotiations on other chapters would be allowed to continue or be opened when ready, the EU asserted that no further chapters would be provisionally closed without resolution of the issues related to the Additional Protocol. Cyprus and France also maintain holds on opening several other chapters of the acquis .
Given the various difficulties with Turkey's membership negotiations, in May 2012, the European Commission launched a "positive agenda" with Turkey to reinvigorate EU-Turkish relations and to inject new momentum into Turkey's accession process. Areas covered by the "positive agenda" included, among others: alignment of Turkish legislation with the EU acquis ; political reforms and fundamental rights; visas; energy; and counterterrorism. The European Commission asserted that this "positive agenda" was intended to complement and support, not replace, Turkey's accession process. Observers note, however, that except for the negotiations establishing a road map for visa-free travel for Turks throughout the EU within three years, it is unclear whether the "positive agenda" has been successful or if it is still in operation in practice.
At the start of 2013, hopes were high that Turkey's EU accession process would be given a boost by the opening of negotiations on at least one new chapter of the acquis (no new chapters had been opened since 2010). The new French government of President François Hollande had announced that it was favorably disposed to rejuvenating Turkey's accession process and was prepared to lift its hold on opening the regional policy chapter of the acquis . In June 2013, EU leaders agreed to officially open the regional policy chapter, but delayed starting the actual talks because of what they viewed as Turkey's harsh crackdown on anti-government protests (the so-called Gezi park protests) that erupted in late May-early June. In November 2013, following the release of the Commission's annual progress report on Turkey, formal negotiations began on the regional policy chapter, although little progress has been achieved to date. A recent scandal inside the government of Turkish Prime Minister Recep Tayyip Erdogan resulted in the replacement of Turkey's Minister for EU Affairs, who was Turkey's chief accession negotiator.
Among most observers, there is little doubt that the EU accession process has been a major motivation behind Turkey's internal march toward reform and democratization. It has been a positive factor in helping transform Turkey's political and military institutions, its leadership, and its political culture, both at the national and, in some respects, the local government level. The accession process has also benefitted Turkey's economy. Many credit Turkey's customs union with the EU as being instrumental in Turkey's recent economic boom and its increasing economic competitiveness. As a candidate country, Turkey also receives almost $1 billion annually from the EU to help it meet EU standards and implement political and economic reforms.
Some analysts assert that the EU accession process has also helped forge closer relations between Europe and Turkey. Economic ties between the EU and Turkey, despite the problems within the Eurozone, have expanded over the past several years with nearly half of Turkey's exports flowing to Europe. Turkey's strong and growing economy offers a large and important market for European goods and services, and is expected to do so for a long time. Turkish businesses are flourishing in parts of Europe, and Turkey has become a magnet for foreign direct investment, with much of that flowing from Europe. Turkey's role as an important energy hub and transit region for European energy supply diversification continues to grow, as was seen recently with the decision to construct the Trans-Adriatic Pipeline (TAP), which will bring natural gas from Azerbaijan across Turkey, via the Trans-Anatolian Pipeline (TANAP), into Italy and parts of Europe. Geopolitically, continuing instability in Europe's southern neighborhood of North Africa and the Middle East, including the ongoing civil war in Syria, suggests that a closer "strategic dialogue" with Turkey on foreign policy issues could become a more regular and important feature of the Turkey-EU relationship. These examples reinforce the belief among many that the EU and Turkey need each other for a multitude of reasons.
Nevertheless, experts contend that the slow pace of Turkey's progress toward EU membership suits some EU governments and many EU citizens who question whether Turkey should join the EU. Those of this view remain wary about the implications of Turkey's accession on the Union's institutions and finances given Turkey's size (with nearly 80 million people, Turkey would rival Germany as the largest EU country in terms of population), and the comparatively large portion of Turks considered poor in economic terms. Despite Turkey's improving economy, some in the EU still fear an influx of Turkish laborers, who would have the right to live and work in existing EU member states should Turkey accede to the Union. Many EU leaders and publics also worry that Turkey's predominantly Muslim culture would fundamentally alter the character, policies, and identity of the Union. In addition, EU concerns persist about the status of Turkish political reforms, the observance of fundamental rights such as freedom of expression and assembly, the independence of its judiciary, women's rights, the degree of media freedoms, and the extent to which religious and ethnic minorities are protected. Thus, European support for Turkey, never really that strong among the average citizenry, now seems even more ambivalent.
Analysts predict that at best, Turkish membership in the EU is at least another decade away. Moreover, they note that it is highly unlikely that Turkey would be able to join the EU without a political settlement on the divided island of Cyprus. A number of observers point out that some Turkish policy makers and citizens are also increasingly questioning the value of and need for Turkish accession. For many Turks, EU membership seems to have lost its appeal; one recent public opinion poll in 2013 found that only 44% of Turkish respondents believed that Turkey should join the EU (in comparison to 73% in 2004). Turkey's economy continues to expand, despite a slowdown in growth over the last two years, and Ankara has been seeking to reposition and strengthen itself in its own neighborhood between secular Europe and the Islamist emergence in the Middle East. Many Turks seem to feel "being European" or gaining membership in the Union is no longer needed in order to secure Turkey's status or to have an otherwise normal partnership with Europe.
Some commentators suggest that a revitalized "positive agenda" may ultimately provide a way for both Turkey and the EU to back away from full EU membership for Turkey, while allowing for the development of stronger Turkish-EU ties. Turkish officials, however, continue to assert that EU membership remains a priority for Turkey. And many experts contend that neither Turkey nor the EU, at present, appears prepared to end Turkey's accession process.

	Prospects for Future Rounds of EU Enlargement

As noted previously, the EU asserts that the enlargement door remains open to any European country that is able to meet and implement the political and economic criteria for membership. The remaining Western Balkan states of Albania, Bosnia-Herzegovina, and Kosovo are all officially recognized by the EU as potential candidates, but their accession prospects and timetables vary (see the text box on the next page for more information); most analysts believe that it will likely be many more years before any of these countries are ready to join the EU. Nevertheless, the EU hopes that the possibility of membership will help accelerate reforms and promote greater stability in these and other states interested in eventual EU accession.
Some countries of "wider Europe," usually considered to include Ukraine, Moldova, and the southern Caucasus (Georgia, Armenia, and Azerbaijan), have also expressed long-term EU aspirations. In contrast to the Western Balkans, the EU has not formally recognized a membership perspective for any of the countries of "wider Europe," but Georgia and Moldova, in particular, harbor hopes of joining the EU one day, and successive Ukrainian governments have supported EU membership to varying degrees. In November 2013, Georgia and Moldova initialed respective Association Agreements (AA) with the EU; an AA sets out the broad framework for cooperation between the EU and a partner country, and seeks to promote European political values and deeper economic ties. Many view the conclusion of an AA as a necessary first step on the path to eventual EU accession (however, AAs do not represent an EU membership commitment). Although the current Ukrainian government of Viktor Yanukovych has formally supported EU integration for Ukraine and had been expected to sign its AA in November 2013, Yanukovych declined to do so because of intense Russian opposition. This decision sparked massive pro-EU and anti-government protests in Ukraine, some of which have since turned violent, and led to a serious political crisis.
On the other hand, "enlargement fatigue" has become a serious issue in Europe. Despite Croatia's recent accession and the EU's membership commitment to the other Western Balkan countries, experts assert that a number of European leaders and many EU citizens remain cautious about further EU enlargement. This is especially true with respect to Turkey or the countries of "wider Europe." EU officials increasingly stress that the process of enlargement must take into account the Union's "integration capacity." In other words, acceding countries must be ready and able to fully assume the obligations of EU membership, and additional EU enlargement must not endanger the ability of the EU's institutions to function effectively or render EU financing arrangements unsustainable.
Apprehensions about continued EU enlargement seem to be driven by several issues. Some EU policy makers and European publics have long worried that the addition of nations with weak economies and low incomes could lead to an influx of low-cost or unwanted migrant labor. Such fears prompted the EU to allow the "old" member states to institute some temporary restrictions (of up to seven years) on labor migration from those countries that joined the EU in 2004 and 2007. Although EU members that chose not to impose any transitional restrictions (such as the UK and Ireland) did see an increase in workers from Central and Eastern Europe, most studies since 2004 suggest that the proportion of EU citizens moving from east to west following enlargement has been relatively small and that such migrants have not displaced local workers or significantly driven down local wages. Nevertheless, such concerns persist, especially when considering the accession of big, relatively less affluent countries such as Turkey or possibly Ukraine in the longer term. Similar to those allowed following the 2004 and 2007 enlargement rounds, EU member states may impose temporary labor migration restrictions on Croatian nationals following Croatia's 2013 accession.
The addition of large countries like Turkey or Ukraine could also have substantial financial consequences for the Union's budget and regional assistance programs, as well as implications for the functioning of certain EU institutions. Some key EU member states may fear that an ever-expanding Union could ultimately weaken their ability to set the tone and agenda in EU institutions and to drive EU policies. Moreover, doubts persist about the ability of some potential EU aspirants to implement EU standards, especially in areas related to the rule of law, fundamental rights, and anti-corruption measures.
Another broad European concern with respect to ongoing enlargement is with the overall identity of Europe, what the Union stands for, and where "Europe" ends. The Union's struggle with these issues has been highlighted by the possible admission of Turkey with an Islamic culture perceived by many Europeans to be vastly different and not compatible with Europe. Similarly, some in the EU question whether countries like Ukraine or those of the southern Caucasus should be considered as part of "Europe," or whether their geography, history, and culture make them distinct. Many experts believe that enlargement may soon be reaching its limits and that the EU is unlikely to include the countries of "wider Europe" for the foreseeable future.
Moreover, commentators suggest that the EU's recent economic problems and sovereign debt crisis—which have hit the countries of the Eurozone particularly hard—could potentially slow future rounds of EU enlargement. They note that EU leaders are grappling not only with trying to remedy the Eurozone's financial troubles, but also with uncertainty about the future direction of the EU itself. As a result, they may be less inclined to robustly push forward the enlargement agenda. Conversely, the EU's economic difficulties might make joining the Union—and ultimately the common currency—less attractive for some current and potential EU candidates. For decades, many countries aspired to join the EU largely for the economic benefits that membership would bring. Now, aspirants such as Turkey—with a dynamic economy—may not view the benefits of membership as outweighing the potential constraints on its sovereignty and national fiscal and monetary policies.

	U.S. Perspectives

The United States has strongly supported the European integration project since its inception in the 1950s. Successive U.S. Administrations and many Members of Congress have long backed EU enlargement, believing that it serves U.S. interests by advancing democracy and economic prosperity, and thereby creating strong European political allies and trading partners. Following the collapse of communism in 1989, U.S. and EU officials worked in close cooperation to promote democratic transitions and market-oriented reforms, with both sides of the Atlantic routinely asserting that the countries of Central and Eastern Europe would be warmly welcomed into Euro-Atlantic institutions such as the EU, as well as NATO, but only if they met the necessary political and economic criteria.
Some analysts suggest that U.S. policy makers have also been keen to promote EU enlargement because they have viewed it as a way to decrease U.S.-EU tensions given that many of the newer members are often regarded as more pro-American. Moreover, many U.S. officials hoped that with the EU's enlargement to the east and the transformation of the continent nearly complete, the EU would turn its attention outward and be a more capable partner for the United States in tackling a range of global challenges. U.S. business and commercial interests have also generally favored EU enlargement, believing that it would provide access to a larger, more integrated European market, and that it would help further reforms of the EU's regulatory regime and common agricultural policy, frequent sources of U.S.-EU trade conflicts.
Over the years, the only significant U.S. criticism of the EU's enlargement process has been that the Union was moving too slowly, especially with respect to Turkey. Successive U.S. Administrations and many Members of Congress have long advocated EU membership for Turkey, viewing it as a vital, strategic ally that should be anchored firmly to Europe. At times, Washington has played an active, albeit small, role in Turkey's EU accession path; in 1999, for example, the Clinton Administration reportedly lobbied Ankara to accept the EU's offer to recognize Turkey as an official EU candidate, despite Ankara's unhappiness that the EU had not set out a timetable for accession talks. Periodically, however, U.S. pressure to promote Turkey's EU accession prospects has generated tensions with the EU. 
The United States continues to support Turkey's EU membership bid, as well as the EU aspirations of the Western Balkans. In the midst of the recent protests and violence in Ukraine, U.S. officials and some Members of Congress have stressed U.S. backing for those in Ukraine who see the country's future as being aligned with Europe. At the same time, U.S. policy makers realize that EU enlargement moves at its own pace, and that EU accession for Turkey and other countries is still many years away. Some U.S. officials remain concerned that "enlargement fatigue," as well as the EU's financial crisis, could hinder additional EU expansion.
Other commentators argue that EU enlargement could have some negative implications for U.S. interests. Even with EU institutional reforms, some assert that EU decision-making remains cumbersome and that enlargement has done little to make the EU a more coherent actor on the world stage. For example, they contend that the addition of the Central and Eastern European countries has created more divisions on certain issues, such as EU policy toward Russia, and that the EU is largely still preoccupied with its own internal problems. On the other hand, some pundits worry that despite the EU's current financial difficulties, a larger EU—with an economic output roughly equivalent to that of the United States and growing political clout—could ultimately rival U.S. power and prestige in the longer term.

Summary:
The European Union (EU) has long viewed the enlargement process as an extraordinary opportunity to promote political stability and economic prosperity in Europe. Since 2004, EU membership has grown from 15 to 28 countries, bringing in most states of Central and Eastern Europe and fulfilling an historic pledge to further the integration of the continent by peaceful means. Croatia is the EU's newest member, acceding to the EU on July 1, 2013.
Analysts contend that the carefully managed process of enlargement is one of the EU's most powerful policy tools, and that, over the years, it has helped transform many European states into functioning democracies and more affluent countries. The EU maintains that the enlargement door remains open to any European country that fulfills the EU's political and economic criteria for membership. At the same time, EU enlargement is also very much a political process; most all significant steps on the long path to accession require the unanimous agreement of the existing 28 member states. As such, a prospective EU candidate's relationship or conflicts with individual member states may also influence a country's EU accession prospects and timeline.
Currently, five countries are recognized by the EU as official candidates for membership: Iceland, Macedonia, Montenegro, Serbia, and Turkey. All are at different stages of the accession process. While Montenegro and Serbia have only recently begun accession negotiations, Turkey's accession talks have been underway since 2005. Macedonia's accession negotiations have not yet started largely because of an ongoing dispute with Greece over the country's official name. And EU accession talks with Iceland, although relatively advanced, have been on hold since May 2013, when a new Icelandic government largely opposed to EU membership took office. The EU also considers the remaining Western Balkan states of Albania, Bosnia-Herzegovina, and Kosovo as potential EU candidates, but most experts assess that it will likely be many years before any of these countries are ready to join the EU.
Despite the EU's professed commitment to enlargement, some EU policy makers and many EU citizens are cautious about additional expansion, especially to Turkey or countries farther east, such as Georgia or Ukraine, in the longer term. Worries about continued EU enlargement range from fears of unwanted migrant labor to the implications of an ever-expanding Union on the EU's institutions, finances, and overall identity. Such qualms are particularly apparent towards Turkey, given its large size, predominantly Muslim culture, and comparatively less prosperous economy.
Successive U.S. Administrations and many Members of Congress have long backed EU enlargement, believing that it serves U.S. interests by advancing democracy and economic prosperity throughout the European continent. Over the years, the only significant U.S. criticism of the EU's enlargement process has been that the Union was moving too slowly, especially with respect to Turkey. Some U.S. officials are concerned that "enlargement fatigue" as well as the EU's economic and financial troubles, which have hit the countries that use the EU's common currency (the euro) particularly hard, could potentially slow future rounds of EU enlargement.
The status of EU enlargement and its implications for both the EU itself and U.S.-EU relations may be of interest to the 113th Congress.
