The Soviet Responses to Truman Doctrine and Marshall Plan:

In response to the Truman Doctrine and the Marshall Plan, which the Soviets saw as a concerted effort to encircle them, Stalin organized the Informational Bureau of Communist Parties (Cominform) in September 1947.

This was an effort to unify communist parties around the world and to put up a united front against capitalist aggression.

In January 1949, the Soviets organized the Council for Mutual Economic Assistance (Comecon), a Russian version of the Marshall Plan designed to aid Eastern Europe in postwar reconstruction.

It was also used to bind together the economies of the Soviet bloc, all under Moscow’s strict supervision.
