After the formation of NATO in 1949, which effectively united the Western Bloc against the Eastern Bloc, Chairman Stalin of the Soviet Union began to seek to form closer ties between the other Communist nations. By using Cominform, he had already gained a great deal of control over other Eastern nations.
Based out of Bucharest, the Cominform was highly associated with Stalin. After Lavrentiy Beria took power in the Soviet Union, he called one final conference of the Cominform. At this conference, in 1955, Beria and Malenkov outlined the Soviet proposal for the Bucharest Pact, which promised less interference in local politics by the Soviet Union. The Pact was passed with resounding support of all nations' leaders.
