Belarus–Lithuania border near Sakalinė
|Length||679 kilometres (422 mi)|
|Current shape||February 6, 1995|
The Belarus–Lithuania border is an international border almost 679 km (422 mi) in length between the Republic of Belarus (CIS member) and the Republic of Lithuania (EU member) and also serves as an outer border of the European Union and the eastern border of the Commonwealth of Independent States. The border is defined by the treaty of February 6, 1995 between the two countries. The ground demarcation of the border was completed in 2007.
380 km (240 mi) of the border is on land, while 299 km (186 mi) are on water, crossing lakes, e.g. Lake Drūkšiai and following some rivers, e.g. Dysna River and Neman River. The border is based on the border between the Lithuanian Soviet Socialist Republic and Byelorussian Soviet Socialist Republic within the Soviet Union, which had remained largely stable since 1940.
Since 2004 the border has served as the outer border of the European Union and, since 2007, the Schengen Area. These developments brought increased border controls and stricter visa requirements for crossing between the two countries. An agreement signed in 2010 aims to implement simplified traveling for people living within 50 km (31 mi) of the border. As an outer border of EU, the border with Belarus has seen the most illegal attempts to cross the border in Lithuania, with 246 attempts in 2010.
