Based on the diverging interests of Germany and Poland as influential members of the European Union on the Eastern Partnership (EaP), the contributions in the anthology analyse specifics and current problems of the states in EU's Eastern neighbourhood. By including the interests of Russia and the USA, which go beyond the EU, the geostrategic implications of these relations for the Eurasian region will also be highlighted. The studies of renowned German and Polish experts represent the results of individual research and bilateral exchange on the current state of EU's relations towards its Eastern neighbours.
