Foreign relations of Thailand

Template:Short description Template:Use dmy dates The foreign relations of Thailand are handled by the Ministry of Foreign Affairs of Thailand.

Thailand participates fully in international and regional organizations. It has developed close ties with other ASEAN members—Indonesia, Malaysia, the Philippines, Singapore, Brunei, Laos, and Vietnam—whose foreign and economic ministers hold annual meetings. Regional cooperation is progressing in economic, trade, banking, political, and cultural matters. In 2003, Thailand served as APEC host. Dr. Supachai Panitchpakdi, the former Deputy Prime Minister of Thailand, served as Secretary-General of the United Nations Conference on Trade and Development (UNCTAD) from 2005 until 31 August 2015. In 2005 Thailand attended the inaugural East Asia Summit.

Since the military coup of May 2014, Thailand's global reputation has plunged, according to Professor Thitinan Pongsudhirak of Chulalongkorn University. He maintains that, "When the fourth anniversary of Thailand's coup comes to pass later this month [May 2018], Thailand's foreign relations will be one of the many costs to be counted from the military government....Instead of moving ahead in its relations with the outside world, Thailand has regressed to a standstill.

Disputes

Parts of the border with Laos are undefined. A maritime boundary dispute with Vietnam was resolved, August 1997. Parts of maritime border with Cambodia are disputed. Sporadic conflict with Myanmar over alignment of border.

Asia

ASEAN

Country	Formal relations began	Notes
Brunei	1 January 1984	See Brunei–Thailand relations Brunei has an embassy in Bangkok, and Thailand has an embassy in Bandar Seri Begawan. The relations have always been close and cordial. Both countries are also members of the Non-Aligned Movement and the Asia-Pacific Economic Cooperation.
Cambodia	19 December 1950	See Cambodia–Thailand relations Parts of Cambodia's border with Thailand are indefinite, and the maritime boundary with Thailand is not clearly defined. On 5 November 2009 Thailand recalled its ambassador from Cambodia in protest of the Cambodian government's appointment of Thai ex-leader Thaksin Shinawatra as an economic adviser. Thai Prime Minister Abhisit Vejjajiva stated that this was "the first diplomatic retaliation measure" against the appointment. He also said that Cambodia was interfering in Thai internal affairs and as a result bi-lateral co-operation agreements would be reviewed. The Cambodian government has stated that it would refuse any extradition request from Thailand for Thaksin as it considered him to be a victim of political persecution. In the months leading up to the Cambodian decision, troops from both nations had clashed over territory claimed by both countries immediately adjacent to Preah Vihear, an 11th-century Hindu temple, leading to a deterioration in relations. At 20:30 on 5 November Cambodia announced that it was withdrawing its ambassador from Thailand as a retaliatory measure. Sok An, a member of the Council of Ministers and Deputy Prime Minister of Cambodia, said that the appointment of Thaksin is a decision internal to Cambodia and that it "conforms to international practice". The mutual withdrawal of ambassadors is the most severe diplomatic action to have occurred between the two countries. Thailand has an embassy in Phnom Penh, while Cambodia has an embassy in Bangkok.
Indonesia	7 March 1950	See Indonesia–Thailand relations Indonesia and Thailand are viewed as natural allies. Indonesia is Thailand's third most important trade partner within ASEAN, with bilateral trade worth $8.7 billion in 2007. Trade between the two countries is set to grow over the years. Following the military takeover of the government in Thailand in May 2014, Indonesia supports the restoration of democracy in Thailand. Indonesia urged the military and civilian elements in Thailand to work together to quickly restore the political situation in Thailand. Thailand has an embassy in Jakarta and honorary consulates in Denpasar, Medan and Surabaya. Indonesia has an embassy in Bangkok and a consulate in Songkhla. Both countries are also members of the Asia-Pacific Economic Cooperation, Non-Aligned Movement, Cairns Group, Indian-Ocean Rim Association and G20 developing nations.
Laos	19 December 1950	See Laos–Thailand relations In some respects, Thailand can be seen as a greater threat to Laos's independence than Vietnam because of its closer cultural affinity, its easier access, and its control over the railroad and highway routes to the sea. The Mekong River, which both sides have an interest in making a "river of true peace and friendship" — as their respective prime ministers called for in 1976 – also provides a north–south artery during the rainy season. Thailand has an embassy in Vientiane and a consulate-general in Savannakhet. Laos has an embassy in Bangkok and a consulate-general in Khon Kaen.
Malaysia	31 August 1957	See Malaysia–Thailand relations Thailand has an embassy in Kuala Lumpur, and consulate-general offices in George Town and Kota Bharu. Malaysia maintains an embassy in Bangkok. Recently, Thai-Malay relations have soured considerably due to the ethnically Malay Pattani separatists in three southern provinces of Thailand. There have been claims by some Thai politicians that certain parties in Malaysia has taken an interest in the cause of their opponents in the war, which is vehemently disputed by the latter. Both countries also members of the Asia-Pacific Economic Cooperation, Non-Aligned Movement, Cairns Group and Indian-Ocean Rim Association.
Myanmar	24 August 1948	See Myanmar–Thailand relations Myanmar has an embassy in Bangkok and a consulate-general in Chiang Mai. Thailand has an embassy in Yangon.
Philippines	14 June 1949	See Philippines–Thailand relations Thailand is one of the Philippines' major trading partners and one of the Philippines' rice suppliers. Relations continue to be strengthened through talks and agreements on economic, security, and cultural matters including concerns on rice trading, and combatting drugs and human trafficking. Thailand has an embassy in Manila and an honorary consulate in Cebu. The Philippines has an embassy in Bangkok. Both countries are the only Major non-NATO Allies in Southeast Asia. Both countries are also members of the Asia-Pacific Economic Cooperation, Non-Aligned Movement, Cairns Group and G20 developing nations together with Indonesia. A Treaty of Friendship was signed by both countries on June 14, 1949.
Singapore	20 September 1965	See Singapore–Thailand relations Bilateral relations between the two nations formally date to 1965, when Thailand established diplomatic relations soon after the independence of Singapore. Both countries share close defence ties, regularly sending personnel for cross training and holding various annual exercises between Singapore Armed Forces and Royal Thai Armed Forces. Thailand has an embassy in Singapore. Singapore has an embassy in Bangkok. Both countries are also members of the Asia-Pacific Economic Cooperation, Non-Aligned Movement and Indian-Ocean Rim Association.
Vietnam	6 August 1976	See Thailand–Vietnam relations Diplomatic relations between the two countries have existed since 1976, and are very friendly both economically and politically nowadays. Yet, relations between the two countries had always been marred by discord, which resulted from bitter rivalry to gain control of the area of what is today Laos and Cambodia. In the 19th century, Thailand (then known as Siam) had fought a series of wars with the Nguyễn dynasty which then ruled over Vietnam over control of Cambodia. This rivalry will only temporarily subside when French colonists stepped in and gradually building an establishment in Southeast Asia, known as French Indochina. During the Vietnam War, Thailand was aligned with South Vietnam and the United States and the U Tapao Air Base was used as a base for USAF aircraft. During the Fall of Saigon in 1975, fleeing South Vietnamese pilots arrived at U Tapao before fleeing to other countries. In 1979, when the Khmer Rouge government in neighbouring Cambodia was toppled, this had raised concerns in Thailand and the Thai government quickly allied itself with the Khmer Rouge, later the CGDK, in fear of Vietnamese expansionism. In fact, Thailand was foremost among the ASEAN, of which it is part of, in opposing the Vietnamese invasion of Cambodia. Cambodian refugees soon stayed at border camps straddling the Thai-Cambodian border, and these camps are often controlled by the Khmer Rouge or the CGDK. In the years that followed, Vietnam launched a series of raids on the camps and Vietnamese troops often penetrated into Thai territory and shelled Thai border villages and towns. Thailand has an embassy in Hanoi and a consulate-general in Ho Chi Minh City. Vietnam has an embassy in Bangkok and a consulate-general in Khon Kaen. Both countries are also members of the Asia-Pacific Economic Cooperation and Non-Aligned Movement.

British interests in Thailand are represented through the British Embassy on Witthayu Road, Lumphini, Pathum Wan in Bangkok and honorary consulates in Chiang Mai, Pattaya, Phuket, and Surat Thani British relations with Thailand date back to 1612, when the East India Company ship The Globe arrived in Siam carrying a letter from King James I for the Siamese king. After Burma lost the First Anglo-Burmese War (1824–26) relations opened between the Rattanakosin Kingdom of Siam and the United Kingdom with a treaty of alliance in February 1826 and another treaty in June negotiated by East India Company emissary Henry Burney. This was followed by the Bowring Treaty of 1855 to liberalise trade. In 1893, Lord Lansdowne of the British Raj finalized the border between Burma and Siam; the Anglo-Siamese Treaty of 1909 then dissected the northern Malay states. In 1917 the modern Siamese kingdom declared war on Germany during World War I, which secured it a seat at the Versailles Peace Conference. Foreign Minister Devawongse Varopakarn used this as an opportunity to argue for the repeal of the 19th century treaties and restoration of full Siamese sovereignty. While Britain and France delayed until 1925, the United States obliged in 1920. Following the outbreak of World War II, relations with Britain, France and the United States deteriorated rapidly – though former Queen Rambai Barni was nominal head of the Seri Thai resistance movement in Great Britain. Japan allowed Thailand to resume sovereignty over the sultanates of northern Malaya that had been lost in the 1909 treaty with Britain, and to invade and annex the Shan States in northern Burma. After the Japanese surrender, Allied military responsibility for Thailand fell to the British, who favoured treating the kingdom as a defeated enemy. Americans, however, supported Thailand's new government; during the Cold War relations with the United Kingdom took a back seat to those with the United States.
