Singapore–Vietnam relations

Singapore–Vietnam relations refer to the bilateral relations between the Republic of Singapore and the Socialist Republic of Vietnam. Singapore and Vietnam started the trade relations in the 19th century. Sir Thomas Bingley Raffles founded the British colony of Singapore in 1819, while the French had founded Cochinchina in 1862 with Saigon as its capital which will later formed itself as French Indochina when the capital moved to Hanoi. Due to the anti-communist policy of Singapore, Singapore supported South Vietnam before the Fall of Saigon. Singapore also started formal diplomatic relations with North Vietnam on August 1, 1973. After the unification of Vietnam, Singapore started to improve its relations with the Socialist Republic of Vietnam. Relations worsened during the Cambodian–Vietnamese War against Angkar and its brutal Maoist movement as the Khmer Rouge cadres of Democratic Kampuchea that was aided by China and Thailand, but have improved once more after the People's Army of Vietnam withdrawal from Cambodia as the Fall of Communism came to a close in 1989 and the collapse of the Soviet Union which marked the end of the Cold War in 1991.

Singapore and Vietnam maintain excellent and multifaceted bilateral relations, and both countries are the members of the Association of Southeast Asian Nations (ASEAN).
