Summary
On May 1, 2004, 10 states joined the European Union (EU), enlarging the Union
to 25 members. The EU views the enlargement process as an historic opportunity to
promote stability in Europe and further the integration of the continent by peaceful
means. In addition to the 10 new members (Cyprus, the Czech Republic, Estonia,
Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia), Bulgaria and
Romania hope to accede to the EU by 2007. Turkey and Croatia are expected to begin
accession negotiations in 2005 provided they fulfill certain political conditions.
Macedonia has also applied for EU membership. This report will be updated as
necessary. For additional information, see CRS Report RS21372, The European Union:

Background on the European Union
After World War II, leaders in western Europe and the United States were anxious
to secure long-term peace and stability on the European continent and 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, a single market in these two
industrial sectors that was controlled by an independent supranational authority. In 1958,
the “Rome Treaties” established the European Economic Community, extending the
common market to all economic sectors, and the European Atomic Energy Community
to ensure the use of nuclear energy for peaceful purposes. In 1967, these three formations
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 by increasing the powers of
the European Parliament and enabling the 1992 single market program to move forward.
At the beginning of 1993, the near completion of the single market brought about the
mostly free movement of goods, services, capital, and people within the EC.

to take on the obligations of membership, including adherence to the aims of political,
economic and monetary union.”2 The EU began accession negotiations in March 1998
with Cyprus, the Czech Republic, Estonia, Hungary, Poland, and Slovenia. In December
1999, at its summit in Helsinki, Finland, the EU decided to open negotiations with six
others: Bulgaria, Latvia, Lithuania, Malta, Romania, and Slovakia. Turkey was also
formally recognized as a candidate at Helsinki, but remained in a separate category for
several years as it sought to comply fully with the membership criteria (see below).
Accession talks begin with a screening process to see to what extent applicants meet
the EU’s 80,000 pages of rules and regulations (acquis), which is divided into 31 chapters
that range from free movement of goods to agriculture to competition. Then, detailed
negotiations at ministerial level take place to establish the terms under which applicants
will meet, implement, and enforce the rules in each chapter. The European Commission
proposes common negotiating positions for the EU on each chapter, which must be
approved unanimously by the Council of Ministers; during negotiations, applicants may
request transition periods for complying with certain EU rules. The Commission prepares
annual progress reports outlining achievements and shortcomings on each candidate. All
candidates receive financial assistance from the EU (a total of about $3 billion annually),
mainly to assist in the accession process. Once the Commission concludes negotiations
on all 31 chapters with an applicant, the agreements reached are incorporated in a draft
accession treaty, which is submitted to the Council for approval and to the European
Parliament for assent. After signature, the accession treaty must be ratified by each
member state and the candidate country. This ratification process can take two years.
At their June 2001 summit in Goethenburg, Sweden, EU members stated that the
“enlargement process is irreversible....the road map should make it possible to complete
negotiations by the end of 2002 for those candidates that are ready. The objective is that
they should participate in the European Parliament elections of 2004 as members.”
Specific countries likely to be ready for entry by 2004 were named at the EU’s December
2001 summit in Laeken, Belgium. There, the EU announced that 10 states — 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.
Accession negotiations in 2002 with the 10 candidates on the remaining chapters —
especially agriculture, regional assistance, and budgetary contributions — were
challenging because all raised money and burden-sharing issues. Member states were
divided on how much financial assistance candidates should receive, and on how to
finance it. Meanwhile, the 10 candidates were dismayed by EU proposals that called for
a 10-year transition period before they would be eligible for full EU farm subsidies and
lower rates of structural aid than existing members received. Led by Poland, the
candidates charged that they were being treated like “second-class citizens.” A deal was
finally reached, however, that sought to assuage the candidates with some additional
economic incentives, including more EU money to increase direct payments to farmers
and higher farm quotas in key areas such as milk and wheat. The EU formally concluded
accession talks with the 10 candidates at its December 2002 summit in Copenhagen. The
EU announced May 1, 2004, as its expected accession date and stated that it hoped to
welcome Bulgaria and Romania into the EU in 2007.

The accession treaty was signed by the members and the 10 candidates on April 16,
2003. Although Brussels would have preferred a prior political solution to the conflict
over Cyprus, it had stated repeatedly that this was not a “precondition” for the divided
island’s accession. Moreover, Athens had threatened to block any enlargement that
excluded Cyprus. The EU had hoped that a settlement between the Turkish Cypriot
community in the north and the Greek Cypriot government in the south would be reached
in time for enlargement. Twin referenda on a U.N. plan to reunify the island were held
on April 24, 2004; 65% of Turkish Cypriot voters approved the plan, but it was rejected
by 76% of Greek Cypriot voters. Without a settlement, EU laws and financial benefits
apply only to the southern Greek Cypriot part of the island, which is the internationally
recognized state.
On May 1, 2004, the 10 states acceded to the EU, increasing the EU’s population to
roughly 450 million. The new members, however, still face several challenges. Reforms
in areas ranging from public administration to competition must be completed, and it will
be some time before the new states are ready to join the EU’s monetary union or to
participate fully in the Schengen area of free movement to which most EU members
belong. Citizens of new member states will have to wait up to seven years before they are
able to work in all current EU countries, many of which fear an influx of low-cost labor.
In June 2004, the EU named Croatia as a candidate. The EU asserted, however, that
Croatia still needed to make further progress on some of the political preconditions for
membership related to issues such as minority rights, judiciary reform, and the
apprehension of war criminals. In December 2004, the EU announced it would open
accession negotiations with Croatia in mid-March 2005, provided that Croatia
demonstrated “full cooperation” with the International Criminal Tribunal for the Former
Yugoslavia (ICTY). The start of Croatia’s accession talks, however, is likely to be
delayed because EU member states are not convinced that Croatia is cooperating fully
with the ICTY; Croatia claims that a prominent suspected war criminal demanded by the
ICTY is not in Croatia. Croatia had hoped to be able to join the EU in 2007 with Bulgaria
and Romania, but many observers believe that 2007 is an overly ambitious goal. Also in
December 2004, the EU concluded accession talks with Bulgaria and Romania, and both
appear to be on track for joining the EU in January 2007.
Turkey and the EU
The relationship between Turkey and the European project has been characterized
by a series of ups and downs. Turkey and the EC first concluded an association
agreement aimed at developing closer economic ties in 1963, but Turkey’s 1987
application for full EC membership was rejected. A customs union between the EU and
Turkey entered into force in 1995, but the 1997 Luxembourg summit failed to put Turkey
on a clear track to membership. The EU recognized Turkey formally as a candidate at the
1999 Helsinki summit but asserted that Turkey still needed to comply fully with the EU’s
political and economic criteria. The EU’s decision stemmed largely from improving
Greek-Turkish relations, and Berlin’s more positive attitude toward Ankara. Many
observers suggest that U.S. pressure also played a part. The United States had long
advocated an EU policy shift on Turkey, believing Turkey to be a vital, strategic ally that
should be anchored firmly to Europe. Washington urged Ankara to take the EU’s offer,
even though it did not set out a timetable for accession talks and guaranteed Greece that
Cyprus’ EU bid would not hinge on a settlement of that conflict.

CRS-5
In February 2001, the EU formally adopted an “Accession Partnership” with Turkey,
which set out the priorities Turkey needed to address in order to adopt and implement EU
standards and legislation. The EU provides Turkey with about $150 million annually to
help develop the Turkish economy. Ankara had hoped the EU would set a firm date for
starting negotiations at the December 2002 Copenhagen Summit, but was disappointed.
Some EU members argued that although Turkey had taken some significant steps toward
improving human rights, it still did not fully meet the membership criteria. But in
October 2004, the European Commission recommended opening accession talks provided
that Turkey continued to make progress on democratic and human rights reforms.
After some contentious debates both among EU member states and with Turkish
leaders, the EU agreed at its December 2004 summit in Brussels, Belgium, to open
accession negotiations with Ankara in October 2005. This start date, however, is
conditional on Turkey bringing into force several pieces of reform legislation and on
Turkey fulfilling its pledge to extend its customs union to the EU’s 10 new members,
including Cyprus, thereby granting de facto but not official recognition to the Greek
Cypriot government. The EU asserts that the “shared objective of the negotiations is
accession,” but that it is an “open-ended process, the outcome of which cannot be
guaranteed beforehand.” Some EU member states and many EU citizens remain
extremely wary about Turkey’s possible accession given its size and Muslim heritage.
Accession negotiations with Turkey are expected to take at least a decade to complete.3
Possible Future Rounds of EU Enlargement
The EU maintains that the enlargement door remains open to any European country
ready and able to meet the political and economic criteria for membership. Besides
Croatia, the western Balkan states (Albania, Macedonia, Bosnia, and Serbia) harbor EU
aspirations in the longer term, and the EU has acknowledged these countries as potential
candidates. The EU hopes that the possibility of membership will help accelerate reform
in these countries and promote greater stability. Macedonia submitted its membership
application in March 2004, and hopes to be named officially as a candidate in late 2005
or early 2006.
Although the EU has not officially defined its geographic boundaries, many experts
assert that enlargement is reaching its limits, and that the EU is unlikely to include
countries such as Russia for the foreseeable future. Consequently, in the spring of 2003,
the EU launched a new “European Neighborhood Policy” (EPN) which aims to develop
deeper relations with a “ring of friends,” or countries in close proximity to an enlarged
Union. This initiative covers Russia, Ukraine, Moldova, Belarus, as well as the southern
Mediterranean countries (including Israel and the Palestinian Authority); it offers these
countries a stake in the EU’s internal market and participation in selected EU activities
in return for a demonstrated commitment to EU values and implemented reforms. The
EU already has cooperation or association agreements with some of these neighboring
countries. In June 2004, the EU decided to include the three southern Caucasus states of
Armenia, Azerbaijan, and Georgia in the EPN.

The EU’s Institutional Reform
Key institutional reforms in the EU’s December 2000 Treaty of Nice were intended
to enable the Union to accept new members and still be able to operate effectively. The
Nice Treaty extended the use of majority voting to additional policy areas, reweighted
votes in the Council of Ministers, and capped the size of the Commission. EU officials
heralded the outcome at Nice as opening the door to further EU enlargement. Skeptics
argued, however, that Nice set up an even more complex and less efficient decision-
making process that would lead to institutional gridlock as the Union expands. To
address such criticisms, EU leaders convened a 105-member Convention on the Future
of Europe in March 2002. The Convention sought to streamline EU decision-making
further, review the EU’s functions and structures in an open and public environment,
enhance the EU’s democratic legitimacy, and boost the EU’s visibility on the world stage.
In July 2003, the Convention concluded work on a draft constitutional treaty. Major
innovations include abolishing the EU’s rotating six-month Presidency in favor of a single
individual with longer tenure, creating a new foreign minister, and simplifying EU voting
rules. EU leaders began considering the proposals in this draft treaty in October 2003.
After some fierce disputes, they concluded work on this new treaty in June 2004. It must
now be ratified by all member states. This process will likely take a year or more to
complete; thus, the treaty will probably not take effect until 2006 at the earliest.4
U.S. Perspectives
Successive U.S. Administrations have supported the EU’s enlargement, believing
that it will serve U.S. interests by spreading stability and the benefits of the single market
beyond the EU’s current borders. Members of Congress generally share this view; over
the years, the only criticism has been that the EU was moving too slowly. U.S. businesses
believe they will gain access to a larger, more integrated European market, and see
enlargement as forcing further reform of the EU’s Common Agricultural Policy, a
perennial source of U.S.-EU trade conflict. Some analysts posit that enlargement may
also decrease overall U.S.-EU tensions because many new members are more pro-
American. The Bush Administration has welcomed EU enlargement, noting that it helps
strengthen the “enduring partnership” between the United States and Europe.
Others argue EU enlargement could have some negative implications for U.S.
interests. Even with EU institutional reforms, decision-making will likely remain
cumbersome and the EU may be an increasingly frustrating partner. Some suggest that
political instability in a number of acceding central and eastern European countries may
also further complicate EU negotiations if frequently changing governments shift policy
positions. There is also concern that Cyprus’ accession as a divided island could
complicate the EU’s relationship with Turkey and heighten instability in the Aegean. Still
others worry that a larger, more confident EU — with an economic output of over $9
trillion roughly equivalent to that of the United States and growing political clout — may
increasingly rival U.S. power and prestige.5
