Thanks to consecutive rounds of enlargement and the stepwise broadening and deepening of internal integration, the EU now undeniably plays a key role in international politics, law and economics. At the same time, changes in the international system continue to pose new challenges to the EU. The range of policies implied by the EU's international 'actorness' grows with every summit, and the EU regularly 'imports' and increasingly 'exports' various policies.Against this backdrop, this book series aims to be a central resource for the growing community of scholars and policy-makers interested in understanding the interface between the EU and international affairs. It will provide indepth, cutting-edge contributions to research on the EU in international affairs by highlighting new developments, insights, challenges and opportunities. It will encompass analyses of the EU's international role, as mediated by its own Member States, in international institutions and in its strategic bilateral and regional partnerships. It will further examine the ongoing profusion of EU internal policies with external implications and the ways in which these are both driven by and feed back into international developments. Grounded in political science (and its various sub-disciplines, including International Relations and International Political Economy), law, sociology and history, the series reflects an inter-disciplinary commitment.
