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.
