Speaking with one voice? The European Union's global approach to migration and mobility and the limits of international migration cooperation

Migration is comparatively weakly regulated at the international level. States are reluctant to cede sovereignty over international migration and negotiations between rich destination countries in the north and sending countries in the south must overcome asymmetries of interests. For this reason, issue-linkage is typically required to achieve north–south cooperation. This paper examines the European Union's (EU) Global Approach to Migration and Mobility as a framework for international migration cooperation. The paper argues that institutional complexity and political dynamics internal to the EU limit its capacity to reach agreement with third countries. Three internal factors are examined: contrasting approaches of the Commission and Council to the external dimension; diversity of member states’ interests in migration policy; and the different policy agendas of the European agencies. These factors result in an approach to external migration relations that is limited in scope and characterised by variable participation. Despite its apparent potential to leverage agreements from third countries, the EU emerges as an unpromising vehicle for international migration cooperation.
