Cambodia (Khmer : Kampuchea), 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 kilometers (69,898 sq mi), it is bordered by Thailand to the northwest, Laos to the northeast, and Vietnam to the east, and the Gulf of Thailand to the southwest.
With a population of over 15 million, Cambodia is the 69th most populous country in the world. The official religion is Theravada Buddhism, which is practiced by around 95% of the Cambodian population. The country minority groups include Vietnamese, Chinese, Chams and 30 various hill tribes. The capital and largest city is Phnom Penh; the political, economic, and cultural center of Cambodia.
The kingdom is a constitutional monarchy with Norodom Sihamoni, a monarch chosen by the Royal Throne Council, as head of state. The head of government is Hun Sen, who is currently the longest serving leader in South East Asia and has ruled Cambodia for 30 years.
Rebuilding from decades of civil war, Cambodia has seen rapid progress in the economic and human resource areas. The country has had one of the best economic records in Asia, with economic growth growing an average 6.0% for the last 10 years. Strong textiles, agriculture, construction, garments, and tourism sectors led to foreign investments and international trade. 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.
