Applying realist constructivist theory, this innovative book investigates the migration–development nexus in the European Union’s approach to cooperation with its external partner countries. It explores the reasons why action in this field appears to be irrational and counterproductive and surveys contemporary political dialogues and funding.Combining migration and development policy research, it examines policies and practices on both an international and domestic level. Chapters cover major trends in crisis management and long-term impacts funding between 1985 and 2020, outlining a clear tendency for the EU to bring together ideas, identities and knowledge with self-interest and strategic action. The author introduces two novel concepts: leveraged statecraft and migration statecraft, which amalgamate theoretical traditions in order to construct recognition and partnerships. Case studies analysed in this book include the African, Caribbean and Pacific group of states; the African Union; the European Neighbourhood; the Rabat, Budapest, and Prague processes; and bilateral mobility partnerships.Balancing theory and practice, this is an indispensable read for scholars of European politics and policy, international relations, international political economy, migration, and development studies. It is also highly beneficial to policymakers in the EU as well as external cooperation specialists.
