ENBased on the archival documents of the Council (Rada) of the Belarusian Democratic Republic and articles published in the most important periodicals in exile – "Bats’kaushchyna" and "Bielarus", this paper examines the relations between state representatives of the Belarusians and Lithuanians in the West in the second half of the 1940s and early 1950s. The common problems faced by both Belarusian and Lithuanian emigration structures after the war, necessitated their cooperation in various international organizations and also led to the formation of military and political coalitions in the form of the Baltic-Belarusian and Scandinavian-Baltic-Belarusian alliance. The direct bilateral contacts at the level of political institutions were also of the utmost importance, although the negotiations between the government of the Belarusian Democratic Republic and Supreme Committee for the Liberation of Lithuania, which took place in 1948–51, ended in failure. The main problem was the unresolvable issue of the disputed status of Vilna and the Vilna Region. The mutual accusations put a stop to official Belarusian-Lithuanian contacts and led to tension in the relations between both nations.
