Answer :
Southeast Asian nations have developed into world-class exporters since the 1970s, sending goods like computers and cars around the world.
Following the communists' triumphs in China, North Korea, and North Vietnam, the governments of South and Southeast Asia feared that communism might expand throughout the area. The United States government approached the governments of Australia, New Zealand, Pakistan, the Philippines, and Thailand, as well as France and the UK, in order to establish an anti-communist collective security organisation. This was done out of fear of this "domino effect" and as part of the Truman Doctrine of containing communism. The Southeast Asia Treaty Organization (SEATO), a military alliance akin to NATO in Europe, would result from this.
In the end, South and Southeast Asian countries rejected the U.S. and U.S.S.R. policies of escalating the Cold War. SEATO was a failure.
