The South and Southeast Asian nations accepted both the U.S. and the U.S.S.R. policies of expanding the Cold War.

After the victories of the communists in China, North Korea, and North Vietnam, South and Southeast Asian governments feared that communism would spread through the region. Fearing this "domino effect", and as part of the Truman Doctrine of containing communism, the United States government approached the governments of Australia, New Zealand, Pakistan, the Phillippines and Thailand, as well as France and the UK, in order to create an anti-communist collective security organization. This would become the Southeast Asia Treaty Organization, or SEATO, a military alliance similar to NATO in Europe.

While other countries such as Malaya, Indonesia, South Vietnam and Laos didn't join SEATO, they still agreed to receive protection of the United States. This commitment to protect them from communism ultimately became a major justification for the Vietnam War. However, SEATO was an unsuccessful project, and ultimately, South and Southeast Asian nations rejected both the U.S. and U.S.S.R. policies of expanding the Cold War.
