ABSTRACT
Transboundary interaction can be seen as a product of different motivations, opportunities and strategic concerns; it is conditioned, among other things, by administrative and institutional structures, supranational contexts, policy concerns of the nation-state, culture, language and history. Thus, every international border region is, at any time, characterized by a specific con stellation of political, economic and institutional contexts and relationships that affect the development of transboundary regionalism. Within the Euro pean Union regional transboundary cooperation agencies have been ad vanced as a vital element in the process of interstate integration and as a means for improving the implementation of regional policy. Accordingly, the widely publicized model of Euroregions is being employed in the German-Polish border region - an area characterized by rapid political and economic transformation - as a means of facilitating EU expansion and maintaining a certain degree of spatial cohesion between Central Europe, the new German Länder and the rest of the European Union.
