Cuba–Soviet Union relations
diplomatic relations between the Republic of Cuba and the Union of Soviet Socialist Republics

After the establishment of diplomatic ties with the Soviet Union after the Cuban Revolution of 1959, Cuba became increasingly dependent on Soviet markets and military aid and was an ally of the Soviet Union during the Cold War. In 1972 Cuba joined the Council for Mutual Economic Assistance (Comecon), an economic organization of states designed to create co-operation among the communist planned economies, which was dominated by its largest economy, the Soviet Union. Moscow kept in regular contact with Havana and shared varying close relations until the end of the Soviet Union in 1991. Cuba then entered an era of serious economic hardship, the Special Period.
The relationship between the USSR and the Castro regime were initially warm. The relationship cooled in the aftermath of the Cuban missile crisis to 1968. After 1968, the USSR provided substantial direct economic aid to Cuba. At times, the relationship was contentious, as the Soviet leadership criticized Castro's mismanagement of the Cuban economy and complained about the burden of providing direct aid to Cuba.
History
Relations before Cuban Revolution
The first diplomatic relations between the Soviet Union and Cuba developed during World War II. Maxim Litvinov, the Soviet ambassador to the United States, set up the first Soviet embassy in Havana in 1943, and Cuban diplomats under the auspices of President Fulgencio Batista visited Moscow the same year. The Soviets then made a number of contacts with the communist Popular Socialist Party, who had a foothold in Batista's governing Democratic Socialist Coalition.
