Border status and cooperation
In 2004 the European Union developed the European Neighbourhood Policy for the promotion of cooperation between the EU and its neighbors to the East and South of the European territory of the EU, which, in part, includes the Cross-Border Cooperation programme aimed at the promotion of economic development in border areas and ensuring border security.
