Cambodia (i/kæmˈboʊdiə/; Khmer: Kampuchea, IPA: [kɑmˈpuˈciə]), officially known as the Kingdom of Cambodia, is a country located in the southern portion of the Indochina Peninsula in Southeast Asia. With a total landmass of 181,035 square kilometres (69,898 sq mi), it is bordered by Thailand to the northwest, Laos to the northeast, Vietnam to the east, and the Gulf of Thailand to the southwest. In 2005, oil and natural gas deposits were found beneath Cambodia’s territorial waters, and once commercial extraction begins in 2013, the oil revenues could profoundly affect Cambodia’s economy.
