How did USSR respond to the Marshall plan?

The USSR strongly opposed the Marshall Plan, viewing it as a strategy by the United States to expand its influence in Europe and undermine Soviet control over Eastern Bloc countries. In response, the Soviets established the Cominform in 1947 to coordinate communist parties across Europe and encouraged their satellite states to reject American aid. They also implemented their own economic program, the Molotov Plan, to provide support to Eastern European countries. This division contributed to the deepening of the Cold War tensions between the East and West.
