As the EU and NATO prepare to enlarge, this volume assesses the likely impact on new member states and their neighbours remaining outside these two organizations. Through a combination of thematic and case study chapters it discusses the economic and security implications of enlargement for both ‘insiders’ and ‘outsiders’. Assesses the likely impact of EU and Nato enlargement. Investigates three thematic areas: economic cooperation, security and defence, and free movement of people. Considers five country case studies. Outlines the current relations between the states, how these relate to the past and what effect enlargement will have.
