Geography of Cambodia Cambodia's low mountain ranges - representing the walls of the bowl - remain as the result of only rather recent substantial infrastructural development and economic exploitation - in particular in remote areas - formidably forested.[28] The country is fringed to the north by the Dangrek Mountains plateau, bordering Thailand and Laos, to the north-east by the Annamite Range, in the south-west by the Cardamom Mountains and in the South by the Elephant Mountains. Highlands to the north-east and to the east merge into the Central Highlands and the Mekong Delta lowlands of Vietnam.[29][30]
Vietnam War The Vietnam War (Vietnamese: Chiến tranh Việt Nam), also known as the Second Indochina War,[75] and in Vietnam as the Resistance War Against America (Vietnamese: Kháng chiến chống Mỹ) or simply the American War, was a conflict that occurred in Vietnam, Laos, and Cambodia from 1 November 1955[A 1] to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China[31] and other communist allies and the South Vietnamese army was supported by the United States, South Korea, Australia, Thailand and other anti-communist allies.[76] The war is considered a Cold War-era proxy war by some US perspectives.[77] The majority of Americans believe the war was unjustified.[78] The war would last roughly 19 years and would also form the Laotian Civil War as well as the Cambodian Civil War, which also saw all three countries become communist regimes in 1975.
