Which actions or agreements promoted the containment of communism except?

The containment of communism was primarily promoted through actions such as the Truman Doctrine, which provided military and economic assistance to countries resisting Soviet influence, and the Marshall Plan, which aimed to rebuild European economies to prevent the spread of communism. Additionally, NATO's formation solidified military alliances among Western nations against potential Soviet aggression. However, actions like the policy of détente in the 1970s, which sought to ease tensions with the Soviet Union, are generally seen as efforts to reduce conflict rather than directly promote containment.
