The sixteen neighbors of the European Union are a very mixed bunch. They range from the oil states of Algeria and Libya to wealthy Israel and impoverished Moldova. This group of countries, owing to deep mutual tensions and large geographical distances, either do not or barely talk to each other. The European Neighbourhood Policy (ENP) aims to promote prosperity in and relations with the neighboring countries of the EU. The challenge is to understand the economic situations of this very mixed group of neighboring countries. The emphasis is on the importance of good trade relations and the supportive role of the European neighborhood policy. The volume also examines differences among the twenty-seven member states on a broad spectrum of attitudes and preferences. It considers the latest developments in support for EU membership (high) and involvement with the EU (limited).
