This chapter examines the European Union's key decisions on enlargement as well as the EU's influence on its European neighbours and on the shape of European order. It begins with an overview of the ‘concentric circles’ approach adopted by the EU — then the European Community — to put off the prospect of enlargement and instead proceed with economic and political integration, while strengthening its relations with its European neighbours. It then considers the Copenhagen European Council of June 1993, the Luxembourg and Helsinki European Councils, and the EU's big-bang enlargement. It also analyses the EU's relations with South-Eastern Europe, Turkey, and the ‘wider Europe’. Finally, it explains why the EU member states agreed to a radical reshaping of the European order through enlargement and assesses the future of the enlargement project.

This chapter examines the complexity of the European Union as a foreign policy actor by focusing on its so-called Big Bang enlargement. Three of the largest EU members — Britain, France, and Germany — differed in their beliefs about the implications of enlargement for their own national interests, shifts to the existing balance of power within the EU, the impact on the functioning of EU institutions, and the future of the integration process. The chapter first provides an overview of EU foreign policy before discussing the historic decision to enlarge the EU in 2004 and 2007. In particular, it analyses the significance of European norms in reshaping member states’ interests and the supranational role of the European Commission in framing and implementing the decision to enlarge the EU. It also considers the European Neighbourhood Policy (ENP) as an alternative when the powerful instrument of the EU enlargement is no longer available.
