Kaliningrad Oblast is a Russian exclave lying by the Baltic Sea. In the best interest of Baltic countries, including Poland, is for the Baltic Sea region to be a stable and trustworthy region benefiting from multifaceted international cooperation. In view of the above, the Kaliningrad Oblast of the Russian Federation and its relations with EU states, and especially the closest neighbours have an important role to play. Trading between Poland and Kaliningrad Oblast is developing relatively well, but capital involvement remains well below the potential capacity. The scope of economic cooperation is relatively small. Work on providing security and services to Polish investors in Kaliningrad also remains unsatisfactory.
