This book offers a new look at the European Union's role as a global actor, with special focus on the theme of interregionalism in its relations with key regions around the world: Africa, Asia, South America, North America and Central- Eastern Europe. This new collection clearly shows how, since the end of the Cold War, the European Union has gradually expanded its external relations and foreign policies and become a global actor in world politics. During the last decade, interregionalism has become a key component of the EU's external relations and foreign policies. In fact, the EU has quickly become the hub of a large number of interregional arrangements with a number of regions around the world. Promoting regional and interregional relations not only justifies and enhances the EU's own existence and efficiency as a global 'player', the strategy also promote the legitimacy and status of other regions, giving rise to a deepening of cross-cutting interregional relations in trade and economic relations, political dialogue, development cooperation, cultural relations and security cooperation. This book was previously published as a special issue of the leading "Journal of European Integration."
