Analysing the way in which the EU engages in some of the most important international organizations, this book outlines a framework for analysis within this thriving subject of study. By demonstrating how the EU supports ‘effective multilateralism' and global governance, as well as furthering developments within foreign policy, this volume adopts a novel perspective on the EU as an international player. Seeking to move the focus of study beyond the European Union as itself an international organization, contributors set out to demonstrate EU aspirations to act within international organizations.
