International Relations and the European Union uniquely incorporates the study of the EU's world role into the wider field of International Relations. New chapters on the EU's relationships with emerging world powers, and its stance on energy and environmental policy confirm the second edition as the leading textbook on this subject. Beginning with an examination of theoretical and methodological frameworks, the book goes on to address the institutions and processes that surround the EU's international relations. Areas of key policy substance, such as security and trade are then outlined in detail, alongside the EU's relations with specific countries including the United States, China, India and Russia. The second edition of International Relations and the European Union is thoroughly up-to-date with all the latest developments including the ratification of the Lisbon Treaty and the consequences of the global financial crisis. Contributions from leading experts encourage students to think critically about the EU's role in world politics over the last fifty years and ask: who and what is the EU for, in its international relations? What should it be trying to achieve?
