Beginning in 1977, the Thai government under Prime Minister Kriangsak had sought a rapprochement with Indochina's new communist states. Trade agreements and a transit accord were signed with Laos in 1978. In September of that year, Pham Van Dong, premier of Vietnam, visited Bangkok and gave assurances that his government would not support a communist insurgency within Thailand. Troubles on the Thai-Cambodian border, including assaults on Thai border villages by Cambodian forces, however, continued to disrupt relations with Democratic Kampuchea.
Vietnam's invasion of Democratic Kampuchea in December 1978 initiated a new crisis. Vietnamese forces captured Phnom Penh in January 1979 and proclaimed the People's Republic of Kampuchea--a virtual satellite of Vietnam--a few days later. This action altered Cambodia's position as a buffer between Thailand and Vietnam. Thai and Vietnamese forces now faced each other over a common border, and there were repeated Vietnamese incursions into Thai territory. Moreover, a flood of refugees from Cambodia placed great strains on Thai resources despite the donation of emergency aid by outside nations.
As a frontline state in the Cambodian crisis, Thailand joined the other members of ASEAN, the United States, and China in demanding a Vietnamese withdrawal from Cambodia. In June 1982, the Thai government extended support to the anti-Vietnamese coalition formed by Prince Norodom Sihanouk, the Khmer Rouge's Khieu Samphan, and noncommunist Cambodian leader Son Sann. One unforeseen benefit of the Cambodian crisis was greatly improved relations between Thailand and China, as both countries found themselves in confrontation with Vietnam. By 1983 China had drastically reduced aid and support for the Thai and other Southeast Asian communist insurgencies as part of its new policy of improved relations within the region.
