The European Union has developed a wide array of external relations with its neighbouring countries. Without offering full membership, the EU nevertheless attempts to transfer its rules and policies to non-member countries. It is this extension of EU rules beyond EU borders that the analysis of external governance seeks to capture. The contributions to this volume explain the modes and effects of EU external governance in a variety of EU-non-member country relations in Western Europe, the former Soviet Union, and the Mediterranean region. They cover such diverse issues as trade, environment, security, and democracy promotion and explore the effects of EU institutions, EU power, and the domestic structures of its partner countries on the transfer of EU rules.This book was based on a special issue of Journal of European Public Policy.
