On 31 July 1961, the ASA was established by the foreign ministers of the Federation of Malaya, the Philippines, and Thailand. No formal treaty was signed or ratified. The first of the new Asian-only regional organizations, the ASA generated modest cultural and technical collaboration among its members. Because ASA economies were not complementary and depended to a great extent on agricultural production, intraregional trade was insignificant. However, the ASA set an important precedent by facilitating communication among foreign ministers of culturally and historically diverse independent states. This move toward multilateral cooperation benefited subsequent regional organizations, the most notable of which was the ASA's successor, the Association of Southeast Asian Nations (ASEAN).
After an initial media blitz upon its founding in 1961, the ASA experienced a temporary impasse over renewal by the Philippines of an old claim to Sabah (North Borneo). The ASA was revived following the 1965 collapse of Indonesian President Sukarno's alliance with military officers and communists and the election of President Ferdinand E. Marcos in the Philippines at the end of the year. U.S. President Lyndon B. Johnson praised ASA-type regionalism.
The ASA was a harbinger of a new Asian regionalism. Despite its implicitly anticommunist orientation, foreign ministers of the ASA member states asserted that their purpose was not that of a military-security alliance, presaging elements of the Nixon Doctrine in Asia. Oftentimes, however, the ASA became a rubber stamp for U.S. policies in Asia. In 1967, the ASA's activities were subsumed by ASEAN.
