Glossary: Southeast Asia Treaty Organization (SEATO)
DEFINITION:
Established in September 1954 as a result of the 1954 Geneva Agreements to stop the spread of communism in Southeast Asia. SEATO never had an active military role and was ultimately disbanded in June 1977 following the success of the communist movements in Cambodia, Laos, and Vietnam in 1975. Original signatories to SEATO were Australia, Britain, France, New Zealand, Pakistan, the Philippines, Thailand, and the United States.
