European Union takes a unique approach by incorporating the study of the EU's world role into the wider field of international relations. As the most comprehensive introduction to the EU's international relations written by leading experts in the field, it is the key text for anyone wishing to understand the EU's role in the contemporary world.

Beginning with an examination of theoretical frameworks and approaches, the book goes on to address the institutions and processes that surround the EU's international relations. Key policy areas, such as security and trade, are outlined in detail, alongside the EU's relations with specific countries and regions.

Updates for the fourth edition include new chapters on the EU's relationship with Africa and Asia, coverage of the implementation of the EU's foreign policy, and exploration of how the EU's international relations relate historically to the European integration process, and the contemporary issue of migration.
