Even within the Asia-Pacific, the effect of tripolarity was not to change the fundamental pattern of alliances involving the United States and the Soviet Union but rather to change the position and relations of china. Thus American alliances with South Korea, Japan, the Philippines, Thailand and so on all held, as did the Soviet alliances with Mongolia, North Korea and North Vietnam (soon to be a reunified Vietnam. ) Even the one American international alliance that was ended – that with Taiwan - was soon renewed through domestic American legislation in the form of the Taiwan Relations Act. As against that, china’s relations in the region changed radically, notably in Southeast Asia where relations were soon established with former adversaries Malaysia, the Philippines and Thailand, but deteriorated rapidly with its former ally Vietnam. Moreover the underlying strategic enmity between the United States and the Soviet Union was complicated in the Asia – Pacific by a Sino – Soviet conflict that was particularly intense in the 1970s and whose influence was still apparent for much of the 1980s.
