At the European Council in Copenhagen in December 2002, the European Union (EU) decided to include ten more states in 2004 in its Eastern and Southern expansion and at least a further two-Bulgaria and Romania-by 2007-8. The historical experiences, economic interests and political priorities of most of the new member-states differ substantially from those of the fifteen older memberstates. However, enlargement should prove advantageous both for the EU and the new member-states. For the EU, for example, it will increase its export opportunities, give firms easier access to a skilled workforce to keep ageing Western European societies competitive, and enhance its security on the future border with the successor states of the former Soviet Union, facilitating the better control of illegal migration, drug-trafficking and other new security threats in post-Cold War Europe. For the new member-states, it will facilitate their continued economic transformation, provide better market access in agriculture and other sectors and help to further stabilize their, in some cases, still fragile democracies.
