Nowadays the Arctic becomes a new arena for political and economic interrelation of different states in their will to gain future benefits, which the region can bring. The aim of the thesis is to investigate the Arctic as an area of cooperation and (or) conflict between Russia and three EU states: Denmark, Finland and Sweden as well as the EU itself. This research paper looks on the problem from the perspective of rational- choice theory of international relations, which allows comparing the Arctic strategies of observed actors and their interests in the region. Despite existence of the Arctic Council as a platform for negotiations and multilateral agreements, as well as common will to solve the disputes there is still place for uncertainties in actor' view on the development of the Arctic. For this reason the question of the Arctic region is urgent for all above mentioned countries including the EU, which seeks to take its place in the debate.
