The Kingdom of Cambodia (formerly known as Kampuchea) is a country in South East Asia with the capital and largest city being Phnom Penh. Cambodia is the successor state of the once powerful Hindu and Buddhist Khmer Empire, which ruled most of the Indochinese Peninsula between the eleventh and fourteenth centuries.
Cambodia's main industries are garments, tourism, and construction. In 2007, foreign visitors to Angkor Wat numbered more than 4 million. In 2005, oil and natural gas deposits were found beneath Cambodia's territorial water, and once commercial extraction begins in 2011, the oil revenues could profoundly affect Cambodia's economy.
The country borders Thailand to its west and northwest, Laos to its northeast, and Vietnam to its east and southeast. In the south it faces the Gulf of Thailand. The geography of Cambodia is dominated by the Mekong river (colloquial Khmer: Tonle Thom or "the great river") and the Tonlé Sap ("the fresh water lake"), an important source of fish.
