How was the united states policy of containment after world war 2 related to the development of the marshall plan

Containment was a policy adopted by the United States towards the Soviet Union during the early years of the Cold War. The purpose of this policy was to defeat the Soviet Union by preventing the expansion of the territory under the control of communist regimes.

In this context, the objectives of the United States when launching the Marshall Plan were to rebuild those areas destroyed by the war, eliminate barriers to trade, modernize European industry and make the continent prosperous again; all these objectives were intended to prevent the spread of communism, which had a large and growing influence in post-war Europe.
