Thailand History
Since World War II, no single factor has shaped the style and substance of Thai foreign relations more than the establishment of a communist-run government in China in 1949. The communist triumph aroused a Thai fear of southward Chinese expansion, in which the economically powerful and ethnocentrist Chinese minority in Bangkok might serve as a potential fifth column. Chinese intervention in Korea in 1950 and growing evidence of clandestine communist Chinese roles in local insurgencies in Southeast Asia reinforced Thai resolve to act in concert with other anticommunist nations. The formal installation of a communist administration in Hanoi after the decisive defeat of the French at Dien Bien Phu in May 1954 set the stage for Thailand’s signing of the Manila Pact, a collective security agreement, in September 1954. The resulting Southeast Asia Treaty Organization (SEATO), as the regional body was formally called, had as its members Australia, Britain, France, New Zealand, Pakistan, the Philippines, Thailand, and the United States. SEATO headquarters was in Bangkok.
Nevertheless, Thailand viewed the effectiveness of collective security with some degree of skepticism. On March 6, 1962, in an attempt to allay Thai apprehensions, the United States and Thailand reached a new understanding under what came to be known as the Rusk-Thanat agreement (named after then-Secretary of State Dean Rusk and then-Minister of Foreign Affairs Thanat Khoman). Under the agreement, the United States pledged that, in the event of aggression it would help Thailand unilaterally without prior agreement of all other parties to the Manila Pact.
During the 1960s, Thailand maintained close economic and security ties with the United States, while at the same time striving to foster regional cooperation with its noncommunist neighbors. Its assumption was that regional solidarity and national security were mutually reinforcing and would provide an effective deterrence to communism. In 1961 Thailand joined Malaya (since 1963, Malaysia) and the Philippines in launching the Association of Southeast Asia as a nonmilitary, nonpolitical vehicle for consultation and mutual assistance in economic, cultural, scientific, and administrative matters.
In 1967 the Association of Southeast Asia was replaced by a broader regional group, the Association of Southeast Asian Nations (ASEAN), comprising Indonesia, Malaysia, the Philippines, Singapore, and Thailand. The members agreed to cooperate in food production, industry and commerce, civil aviation, shipping, tourism, communications, meteorology, science and technology, and Southeast Asian studies. Consultation and cooperation were to take place through an annual ministerial conference held in each of the five ASEAN countries in alphabetical rotation. As a result of the formation of the regional organization, consultation between Thailand and the other ASEAN countries on external problems increased greatly in the 1970s.
The Thai response to the external uncertainties of the 1970s was a graphic demonstration of the flexibility of its foreign policy. The external catalyst was an apparent shift in American strategic thinking with regard to China and the Vietnam conflict. The shift was sensed in Bangkok in the late 1960s--in March 1968, when President Lyndon B. Johnson expressed his intention to seek a negotiated peace in Vietnam and again in July 1969, when President Richard M. Nixon told Thai leaders in Bangkok of his intention to lower the future American military profile in Asia without undertaking any new security obligations. At that time, Nixon reaffirmed the United States resolve to "honor its present commitments in Southeast Asia" and to continue its support of Thai efforts in the areas of security and economic development. Not surprisingly, in 1968, before the "Nixon Doctrine" was proclaimed in 1969, Thailand hinted at its desire to open channels of communication with China, the Democratic People’s Republic of Korea (North Korea), and the Democratic Republic of Vietnam (North Vietnam). These channels were considered necessary by the Thai in order to solve difficulties and achieve peaceful coexistence. In late 1970, a government committee was set up to explore the possibility of normalizing relations with China.
After 1971, as the United States and China moved toward reconciliation and detente, Thai soul-searching began in earnest. In 1972 Thailand sent sports teams to China, and in 1973 Thailand made overtures to Hanoi for a dialogue shortly after the United States and North Vietnam signed a cease-fire agreement. In 1974 a Thai delegation conferred with Chinese premier Zhou Enlai in Beijing on measures to improve bilateral relations. At that time Zhou was reported to have assured the Thai delegation that China would stop aiding communist insurgents in Thailand, while underlining his concern over increasing Soviet influence in Southeast Asia. In December 1974, the Thai government lifted a fifteen-year ban on trade with China. In March 1975, a month before Saigon fell, Thailand announced its decision to recognize and normalize diplomatic relations with China.
In the wake of communist takeovers in Phnom Penh and Saigon in April 1975, Thailand moved expeditiously to realign its foreign policy. Thailand’s security ties with the United States-- the pillar of Bangkok’s foreign relations for nearly three decades--were downplayed as part of accentuating a policy of friendship with all nations. In July 1975, the Thai revoked a military accord with the United States under which American troops had been allowed on Thai soil. Thailand also agreed with the Philippines in principle that SEATO, having outlived its usefulness, should be phased out as early as possible. The crowning moment of the policy of readjustment came in July 1975, when Thailand and China signed a formal agreement on establishing diplomatic relations. Noteworthy was the absence of a Chinese demand for the prior removal of American troops from Thailand, in striking contrast to Hanoi’s insistence that Thailand should first renounce its policy of "collusion" with the United States before any reconciliation could take place.
The normalization of relations with its Indochinese neighbors became pressing as refugees from Laos, Cambodia, and Vietnam streamed across the Thai frontier, straining Thai resources and raising tensions in the border regions. Relations with Laos, bound to Thailand by a shared history, religion, ethnicity, culture, and language, were tense. Much of the problem centered on Laotian Meo tribespeople who had taken refuge in Thailand after the communist-led Pathet Lao forces gained control of Vientiane in May 1975. For years the Meo and some Thai irregular troops had waged clandestine operations against the Pathet Lao forces, reportedly with the knowledge and cooperation of the government of Thailand. After intermittent clashes on the Mekong River, Thailand in November 1975 closed the frontier with Laos, causing hardship in Vientiane; this action prevented oil, food, and other essential goods from reaching Laos through Thai territory, the historical transit route to the landlocked country. Tension eased somewhat after January 1976, when the border was reopened following Thai recognition of the new Laotian regime. In August 1976, the two countries signed an agreement on the transport of Laotian goods through Thailand in exchange for Thai air routes over Laos to Vietnam and Hong Kong. Nonetheless, recurring border incidents led to a temporary Thai economic blockade of Laos in late 1977. By the end of the year, Laotian refugees accounted for 73,000 of about 95,000 Indochinese refugees encamped in Thailand.
In April 1975, Thailand was the first country in Southeast Asia to recognize the new regime of the communist thailand/th_glos.asp#Khmer"> Khmer Rouge (see Glossary) in Phnom Penh. In October the two countries agreed in principle to resume diplomatic and economic relations; the agreement was formalized in June 1976, when they also agreed to erect border markers in poorly defined border areas.
Meanwhile, the withdrawal of all American troops from Thailand by July 1976 paved the way for the Thai-Vietnamese agreement in August on normalizing relations. In January 1978, Bangkok and Hanoi signed an accord on trade and economic and technical cooperation, agreeing also to exchange ambassadors, reopen aviation links, resolve all problems through negotiations, and consult on the question of delimiting sea boundaries. Progress toward improved relations with the Indochinese states came to an abrupt halt, however, after Vietnam invaded Cambodia in December 1978, and in January 1979 installed in Phnom Penh a new communist regime friendly to Hanoi.
This invasion not only provoked a Chinese attack on Vietnam in February 1979 but also posed a threat to Thailand’s security. Bangkok could no longer rely on Cambodia as a buffer against Vietnamese power. Bangkok was forced to assume the role of a frontline state against a resurgent communist Vietnam, which had 300,000 troops in Cambodia and Laos. The Thai government began increasing its defense capabilities. While visiting Washington in February 1979, Prime Minister Kriangsak asked for and received reassurances of military support from the United States. His government also launched a major diplomatic offensive to press for the withdrawal of all Vietnamese forces from Cambodia and for continued international recognition of Democratic Kampuchea under Pol Pot’s Khmer Rouge regime. As part of that offensive, Kriangsak also journeyed to Moscow in March 1979--the first visit ever by a Thai prime minister--to explain the Thai position on the Cambodian question and to reassure the Soviets that Thailand’s anti-Vietnamese position was neither anti-Soviet nor pro-Chinese. Such reassurances were believed to be necessary in view of Vietnamese accusations that Thailand collaborated with China and the United States in aiding and abetting the Khmer Rouge forces against the Heng Samrin regime.
The Thai offensive, backed by Bangkok’s ASEAN partners, was rewarded in a United Nations (UN) General Assembly resolution adopted in November 1979. The resolution called for immediate withdrawal of all foreign forces from Cambodia, asked all nations to refrain from interfering in, or staging acts of aggression against, Cambodia, and called on the UN secretary general to explore the possibility of an international conference on Cambodia.
