Frequently asked questions

What is the official name of Cambodia?

The Kingdom of Cambodia — Preah Reacheanachak Kampuchea in Khmer — since the Constitution of 24 September 1993 restored the monarchy. The country has changed its name with each regime: the Khmer Republic from 1970, Democratic Kampuchea under the Khmer Rouge from 1975, the People's Republic of Kampuchea from 1979 and the State of Cambodia from 1989. Kampuchea and Cambodia are the same word, from Kambuja, the name of the Khmer kingdom of the 9th century.

What is the capital of Cambodia?

Phnom Penh, at the meeting of the Mekong, the Tonlé Sap and the Bassac rivers — the capital since 1865, with about 2.3 million people in the city and its province; emptied by the Khmer Rouge in April 1975 and repopulated from 1979. Siem Reap, the gateway to Angkor, and Battambang and Sihanoukville, the port, are the other large cities.

How big is Cambodia, and how many people live there?

About 181,035 km² (69,898 sq mi) — a little smaller than Oklahoma — between Thailand, Laos and Vietnam, with a coast on the Gulf of Thailand. The census of 2019 counted 15,552,211 people; the CIA World Factbook estimates 17.2 million for 2025 and the UN about 17.8 million. The population is young — a median age of about 27 — because of the deaths of 1975–79 and the baby boom that followed.

What are the highest and lowest points of Cambodia?

Phnom Aural, 1,810 m (5,938 ft), in the Cardamom Mountains in the west, is the highest point; the Gulf of Thailand the lowest. The country is a low basin around the Tonlé Sap, the largest freshwater lake in Southeast Asia, drained by the Mekong and ringed by the Cardamoms, the Elephant Mountains and the Dângrêk escarpment on the Thai border; the mean elevation is only about 126 m.

What currency does Cambodia use?

The riel (ISO code KHR, ៛), at about 4,000 to the U.S. dollar — but the dollar circulates alongside it in most of the economy, with the riel used for small change, and the central bank has been pushing its use since 2020. Clocks keep Indochina Time, UTC+7, all year.

Who governs Cambodia?

King Norodom Sihamoni, on the throne since 29 October 2004, reigns; Prime Minister Hun Manet has governed since 22 August 2023, when he succeeded his father Hun Sen after 38 years — Hun Sen now presides over the Senate. The Cambodian People's Party holds 120 of the 125 seats of the National Assembly after the election of July 2023, from which the main opposition party was barred, and every seat of the Senate. The next general election is due in 2028.
