Cambodia General Information


Cambodia is a country in Southeastern Asia, bordering the Gulf of Thailand, between Thailand, Vietnam, and Laos. Its approximate geographical coordinates are 13°N 105°E / 13°N 105°E. Its 2,572 km border is split among Vietnam (1,228 km), Thailand (803 km) and Laos (541 km), as well as 443 km of coastline. Cambodia covers 181,040 square kilometers in the southwestern part of the Indochina peninsula. It lies completely within the tropics; its southernmost points are only slightly more than 10° above the equator. Roughly square in shape, the country is bounded on the north by Thailand and by Laos, on the east and southeast by Vietnam, and on the west by the Gulf of Thailand and by Thailand. Much of the country’s area consists of rolling plains. Dominant features are the large, almost centrally located, Tonle Sap (Great Lake) and the Mekong River, which traverses the country from north to south.


Cambodia falls within several well-defined geographic regions. The largest part of the country, about 75 percent, consists of the Tonle Sap Basin and the Mekong Lowlands. To the southeast of this great basin is the Mekong Delta, which extends through Vietnam to the South China Sea. The basin and delta regions are rimmed with mountain ranges to the southwest by the Cardamom Mountains and the Elephant Range and to the north by the Dangrek Mountains. Higher land to the northeast and to the east merges into the Central Highlands of southern Vietnam.


Two monsoons feature clearly Cambodia’s climate. From November to April, a north-eastern monsoon brings cool air but little rain, while a south-western monsoon, which occurs from May to October, causes heavy winds and rains. During the summer rainy season, rains are likely to take place in the late afternoon.

Cambodia is the most ethnically homogeneous nation in Southeast Asia. More than 95 percent of its 11 million citizens are ethnic Khmers. Chinese Cambodians form the largest minority group, followed by Cham Muslims. Remote mountain areas are home to a number of smaller ethnic groups.

Language in Cambodia

Khmer is the official language and spoken by 95% of the population. Chinese and Vietnamese are also spoken. French was widely spoken until the arrival of the Pol Pot regime and is still taught in schools. English is commonly spoken in Cambodia. It’s estimated that over 50% of the population are conversational in English, but travelers in rural areas may find in hard to communicate in smaller villages.


The official currency of Cambodia is the Riel however US dollars are widely accepted; in fact many businesses set their prices in US dollars. It is however wise to carry some riel around with you for small purchases.

Government & Politics

The signing of the Paris Peace Agreements in October 1991 launched Cambodia in a process of reconstruction after two decades of conflict and civil war. The process, which was backed by a United Nations presence until the first national elections in May 1993, facilitated the foundation of a constitutional monarchy with King Norodom Sihanouk as head of State, and led to the establishment of a power-sharing government.

Type:  Constitutional monarchy, Parliamentary representative democracy
Head of States: His Majesty Samdech Preah Baromneath Norodom Sihamoni (elected October 29, 2004)
Head of Government:   Prime Minister Hun Sen (appointed on January 14 1985, elected in 1998, 2003, and 2008) is in charge of overall execution of national policies and programs, and is accountable to the National Assembly.
