During the Cold War, Thailand sought to prevent the spread of communism so it joined the United States, including participating in SEATO alliance, sending expeditions to Korea and Vietnam, and offering the US to use its base. Thailand is one of the five founding members of Association of Southeast Asian Nations (ASEAN), initially to safeguard against communism. The end of Vietnam War was a turning point in Thai foreign policy and afterwards it sought to improve relations with Communist China and its now-Communist neighbours. Thailand remains an active member of ASEAN and seek to project its influence in it. Thailand has developed increasingly close ties with other members, with progressing regional co-operation in economic, trade, banking, political, and cultural matters.
