Year of Establishment: 1967

Preceded by the Association of Southeast Asia (ASA), ASEAN was first formed to “prevent the spread of communism in the region.” After the end of the cold war, ASEAN expanded to a comprehensive dialogue, covering topics like regional security and multilateral trade. Foreign ministers’s summits or state leaders’s summits were held from time to time to discuss the latest development of security issues in Southeast Asia or the status of individual countries. 

When the Myanmar coup d’etat began in 2021, the international community looked to ASEAN to mediate and have the situation under control. However, ASEAN did not propose specific actions as it is ASEAN’s operating principle not to make public criticism of other states’ domestic affairs or conflicts.
