The Agreement between the Government of Lithuania and the Government of Sweden concerning Delimitation of the Maritime Boundary of the Exclusive Economic Zone and the Continental Shelf in the Baltic Sea was initialed at the meeting of delegations of Lithuania and Sweden on 23 December 2014 in Vilnius. The countries plan to sign the agreement in 2014. The Lithuanian-Swedish maritime boundary, which has a length of about 15 kilometers, is being delimited for the first time in history.
The agreement establishes a single maritime boundary, dividing the continental shelf and exclusive economic zones (EEZ) between the parties. The boundary extends for a distance of about 8 nautical miles (M) and consists of four turning points, of which one is also a definitive terminal point. The northern terminal point, on the other hand, stops just short of the hypothetical tripoint that will have to be settled by means of direct negotiations between all the parties concerned, including Latvia.
The coasts of both countries in the area are opposite. They are characterized by the presence of the island of Öland and Gotland in front of the Swedish coast and by the small, but extended Kursiu promontory in front of the Lithuania, screening about half of its coastline. This promontory encloses the Kursiu lagoon, which has only one natural outlet to the sea at the north in front of the port of Klaipeda. The coastline of Lithuania is outspokenly concave in nature.
Since this boundary corresponds in its entirety to the boundary line previously established between Sweden and the former Soviet Union, this report should be read together with the agreement concluded in 1988 between Sweden and the Soviet Union (Sweden-Soviet Union, to which it is closely linked. It has also to be related to the tripoint agreement between Lithuania, Russia, and Sweden.
This line, as a result, is difficult to explain because it relies on a boundary line that itself was arrived at as the result of a political compromise.
