Eight central and east European states - the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, and Slovenia - are preparing to join the European Union in 2004. Three of these states have already joined Nato; the rest, together with Bulgaria and Romania, will do so by 2004. This edited volume assesses the likely impact of EU and Nato enlargement on relations between those central and east European states which are likely to join in the near future and those destined to remain outside. Looking at three thematic areas (economic and trade relations, security and defence, and free movement of people) and five case studies, the book outlines the current relations between the states, how these relate to the past and what impact enlargement is likely to have on their relationships.
