Cambodia 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.
Agriculture has long been the most important sector of the Cambodian economy, with around 59% of the population relying on agriculture for their livelihood (with rice the principal crop).[5] Garments, tourism, and construction are also important.
