Disintegration of the USSR and join of Baltic States to European Union made this one a border territory between Russia and EU. After the collapse of Former Soviet Union, the new boundary remained almost easy to cross. In the beginning of the 21th century, it became no more fuzzy but rather fixed. Since European enlargement that had taken place in 2004, the crossing has become more regulated. People need visas that meant administrative papers and cost. The evolution of cargo flows has been more contrasted. Economic policies, political stakes and traditional links, are elements to understand East Baltic area. Kaliningrad Oblast, the Russian exclave lying by the Baltic Sea, strengthens the interest of the purpose.
