Cambodia

The Kingdom of Cambodia is the official English name of the country. The English Cambodia is an anglicisation of the French Cambodge, which in turn is the French transliteration of the Khmer កម្ពុជា (Kâmpŭchéa, pronounced [kampuciə]). Kâmpŭchéa is the shortened alternative to the country's official name in Khmer ព្រះរាជាណាចក្រកម្ពុជា (Preăh Réachéanachâkr Kâmpŭchéa, pronounced [preah riəciənaːcak kampuciə]). The Khmer endonym កម្ពុជា Kâmpŭchéa derives from the Sanskrit name कम्बोजदेश Kambojadeśa, composed of देश Deśa ("land of" or "country of") and कम्बोज (Kamboja), referring to the descendants of Kambu (a legendary Indian sage from the ancient Indian kingdom of Kamboja). The term Cambodia was already in use in Europe as early as 1524, since Antonio Pigafetta cites it in his work Relazione del primo viaggio intorno al mondo (1524–1525) as Camogia.

Scholar George Coedes refers to a 10th-century inscription of a Cambodian dynastic legend in which the hermit Kambu Swayambhuva and the celestial nymph Mera unite and establish the Cambodian Solar royal dynasty (Kambu-Mera), that begins with the Chenla ruler Srutavarman and his son Sreshthavarman. Coedes suggests that the Kambu Swayambhuva legend has its origins in southern India, as a version of the Kanchi Pallava dynasty creation myth.

=== Prehistory ===

There exists evidence for a Pleistocene human occupation of what later is Cambodia, which includes quartz and quartzite pebble tools found in terraces along the Mekong River, in Stung Treng and Kratié provinces, and in Kampot province. Some archaeological evidence shows communities of hunter-gatherers inhabited the region during the Holocene: the most ancient archaeological discovery site in Cambodia is considered to be the cave of Laang Spean, which belongs to the Hoabinhian period. Excavations in its lower layers produced a series of radiocarbon dates around 6000 BC. Upper layers in the same site gave evidence of transition to Neolithic, containing the earliest dated earthenware ceramics in Cambodia.

Archaeological records for the period between the Holocene and Iron Age remain equally limited. An event in prehistory was the penetration of the first rice farmers from the north, which began in the third millennium BC. Prehistoric evidence are the "circular earthworks" discovered in the red soils near Memot and in the adjacent region of Vietnam in the latter 1950s. Their function and age are still debated, and some of them possibly date from the second millennium BC. Other prehistoric sites of somewhat uncertain date are Samrong Sen (not far from the ancient capital of Oudong), where the first investigations began in 1875, and Phum Snay, in the northern province of Banteay Meanchey.

Iron was worked by about 500 BC, with supporting evidence coming from the Khorat Plateau, in what later is Thailand. In Cambodia, some Iron Age settlements were found beneath Baksei Chamkrong and other Angkorian temples while circular earthworks were discovered at the site of Lovea kilometres north-west of Angkor. Burials testify to improvement of food availability and trade, and the existence of a social structure and labour organisation. Kinds of glass beads recovered from sites, such as the Phum Snay site in the northwest and the Prohear site in the southeast, suggest that there were two main trading networks at the time. The two networks were separated by time and space, which indicate that there was a shift from one network to the other at about the 2nd–4th century AD, probably due to changes in socio-political powers.

During the 3rd, 4th, and 5th centuries, the Indianised states of Funan and its successor, Chenla, coalesced in what later is Cambodia and southwestern Vietnam. For more than 2,000 years, what was to become Cambodia absorbed influences from India, passing them on to other Southeast Asian civilisations that later became Thailand and Laos.

The Khmer Empire grew out of the remnants of Chenla, becoming firmly established in 802 when Jayavarman II (reigned c. 790 – c. 835) declared independence from Java and proclaimed themselves a Devaraja. They and their followers instituted the cult of the God-king and began a series of conquests that formed an empire which flourished in the area from the 9th to the 15th centuries. During the rule of Jayavarman VIII the Angkor empire was attacked by the Mongol army of Kublai Khan; the king was able to buy peace. Around the 13th century, Theravada missionaries from Sri Lanka reintroduced Theravada Buddhism to Southeast Asia, having sent missionaries previously in the 1190s. The religion spread and eventually displaced Hinduism and Mahayana Buddhism as the popular religion of Angkor; it was not the official state religion until 1295 when Indravarman III took power.

The Khmer Empire was Southeast Asia's largest empire during the 12th century. The empire's centre of power was Angkor, where a series of capitals were constructed during the empire's zenith. In 2007 an international team of researchers using satellite photographs and other modern techniques concluded that Angkor had been the largest pre-industrial city in the world with an urban sprawl of 2,980 km2 (1,151 sq mi). The city could have supported a population of up to 1 million people.

After a series of wars with neighbouring kingdoms, Angkor was sacked by the Ayutthaya Kingdom and abandoned in 1432 because of ecological failure and infrastructure breakdown. The kingdom's capital was eventually moved to Longvek, which prospered as an integral part of the 16th century Asian maritime trade network. The rivalry with the Ayutthaya Kingdom resulted in several conflicts, including the Siamese conquest of Longvek in 1594.

The hill tribe people were "hunted incessantly and carried off as slaves by the Siamese (Thai), the Annamites (Vietnamese), and the Cambodians".

Formerly part of the Khmer Empire, the Mekong Delta came under Vietnamese control in 1698, with King Chey Chettha II having granted the Vietnamese permission to settle in the area decades before.

Siamese and Vietnamese dominance intensified during the 17th and 18th century, provoking frequent displacements of the seat of power as the Khmer monarch's authority decreased to the state of a vassal. Both powers alternately demanded subservience and tribute from the Cambodian court.

In 1863, King Norodom signed a treaty of protection with France. The protectorate of France period lasted until 1953, with a brief interruption while the kingdom was occupied by the Japanese empire from 1941 to 1945 and simultaneously existing as the puppet state of Kingdom of Kampuchea in 1945. Between 1874 and 1962, the total population increased from about 946,000 to 5.7 million. After King Norodom's death in 1904, France manipulated the choice of king and Sisowath, Norodom's brother, was placed on the throne. The throne became vacant in 1941 with the death of Monivong, Sisowath's son, and France passed over Monivong's son, Monireth, feeling he was too independently minded. Instead, Norodom Sihanouk, a maternal grandson of King Sisowath was enthroned. The French thought young Sihanouk would be easy to control. Under the reign of King Norodom Sihanouk, Cambodia gained independence from France on 9 November 1953.

In 1955, Sihanouk abdicated in favour of his father to participate in politics and was elected PM. Upon his father's death in 1960, Sihanouk again became head of state, taking the title of prince. As the Vietnam War progressed, Sihanouk adopted an official policy of neutrality in the Cold War. Sihanouk allowed the Vietnamese communists to use Cambodia as a sanctuary and a supply route for their arms and other aid to their armed forces fighting in South Vietnam. In December 1967 Washington Post journalist Stanley Karnow was told by Sihanouk that if the U.S. wanted to bomb the Vietnamese communist sanctuaries, he would not object unless Cambodians were killed.

The same message was conveyed to U.S. president Lyndon B. Johnson emissary Chester Bowles in January 1968. In public Sihanouk refuted the right of the U.S. to use air strikes in Cambodia, and on 26 March he said "these criminal attacks must immediately and definitively stop". On 28 March a press conference was held and Sihanouk appealed to the international media: "I appeal to you to publicise abroad this very clear stand of Cambodia—that is, I will, in any case, oppose all bombings on Cambodian territory under whatever pretext." Nevertheless, the bombing continued.

While visiting Beijing in 1970 Sihanouk was ousted by a military coup led by PM General Lon Nol and Prince Sisowath Sirik Matak. Once the coup was completed, the new regime, which demanded that the Vietnamese communists leave Cambodia, gained the political support of the United States. The North Vietnamese and Viet Cong forces launched armed attacks on the new government to retain their sanctuaries and supply lines from North Vietnam. The king urged his followers to help in overthrowing this government, hastening the onset of civil war.

Khmer Rouge rebels began using him to gain support. From 1970 until 1972, the Cambodian conflict was largely between the government and army of Cambodia, and the armed forces of North Vietnam. As they gained control of Cambodian territory, the Vietnamese communists imposed a new political infrastructure, which was eventually dominated by the Cambodian communists now referred to as the Khmer Rouge.

Documents uncovered from the Soviet archives after 1991 reveal that the North Vietnamese attempt to overrun Cambodia in 1970 was launched at the explicit request of the Khmer Rouge and negotiated by then second-in-command Nuon Chea. North Vietnamese Army (NVA) units overran Cambodian army positions while the Communist Party of Kampuchea (CPK) expanded their attacks on lines of communication. In response to the North Vietnamese invasion, U.S. President Richard Nixon announced that U.S. and South Vietnamese ground forces had entered Cambodia in a campaign aimed at destroying NVA base areas in Cambodia (see: Cambodian campaign).

On New Year's Day 1975, Communist troops launched an offensive which, in 117 days, led to the collapse of the Khmer Republic. Simultaneous attacks around the perimeter of Phnom Penh pinned down Republican forces, while other CPK units overran fire bases controlling the vital lower Mekong resupply route. A U.S.-funded airlift of ammunition and rice ended when Congress refused additional aid for Cambodia. The Lon Nol government in Phnom Penh surrendered on 17 April 1975, 5 days after the U.S. mission evacuated Cambodia.

Estimates as to how many people were killed by the Khmer Rouge regime range from approximately 1 to 3 million; a cited figure is 2 million (about a quarter of the population). This era gave rise to the term Killing Fields, and the prison Tuol Sleng became known for its history of mass killing. Hundreds of thousands fled across the border into neighbouring Thailand.

While the regime targeted ethnic minority groups at disproportionately higher rates relative to their population size, the absolute majority of victims were ethnic Khmer. The Cham Muslims underwent purges with as much as half of their population exterminated, while forced repatriation in 1970 and deaths during the regime reduced the Vietnamese population in Cambodia from between 250,000 and 300,000 in 1969 to a reported 56,000 in 1984. Khmer Rouge leader Pol Pot was determined to keep his power and disenfranchise any potential threats, escalating violence against the general population.

Professionals, such as doctors, lawyers, and teachers, were heavily targeted. According to Robert D. Kaplan, "eyeglasses were as deadly as the yellow star" as they were seen as a sign of intellectualism. By 1978, the entire legal system was eradicated by the Khmer Rouge regime. Judges and lawyers were executed after being deemed "class enemies", and only 6–12 legal professionals survived and remained in the country. Religious institutions were also targeted, resulting in the destruction of 95% of Cambodia's Buddhist temples alongside vast amounts of Khmer architecture.

In November 1978, Vietnamese troops invaded Cambodia in response to border raids by the Khmer Rouge and conquered it. The People's Republic of Kampuchea (PRK) was established as a pro-Soviet state led by the Kampuchean People's Revolutionary Party, a party created by the Vietnamese in 1951, and led by a group of Khmer Rouge who had fled Cambodia to avoid being purged by Pol Pot and Ta Mok. It was fully beholden to the occupying Vietnamese army and under the direction of the Vietnamese ambassador to Phnom Penh. Its arms came from Vietnam and the Soviet Union.

In opposition to the newly created state, a government-in-exile referred to as the Coalition Government of Democratic Kampuchea (CGDK) was formed in 1981 from three factions. This consisted of the Khmer Rouge, a royalist faction led by Sihanouk, and the Khmer People's National Liberation Front. Its credentials were recognised by the United Nations. The Khmer Rouge representative to UN, Thiounn Prasith, was retained, and he had to work in consultation with representatives of the noncommunist Cambodian parties. The refusal of Vietnam to withdraw from Cambodia led to economic sanctions.

Peace efforts began in Paris in 1989 under the State of Cambodia, culminating two years later in October 1991 in a Paris Comprehensive Peace Settlement. The UN was given a mandate to enforce a ceasefire and deal with refugees and disarmament known as the United Nations Transitional Authority in Cambodia (UNTAC).

In 1993, the monarchy was restored with Norodom Sihanouk reinstated as King, and the first post-war election was coordinated by UNTAC. The election was won by FUNCINPEC led by Sihanouk's son Ranariddh in a hung parliament. A power-sharing agreement was agreed with Ranariddh and Hun Sen of the Cambodian People's Party both simultaneously being co-PMs after the CPP threatened to secede part of the country if power was fully transferred to FUNCINPEC. The stability established following the conflict was shaken in 1997 by a coup d'état led by the co-PM Hun Sen, who ousted Ranariddh and other parties represented in the government and consolidated power for CPP. After its government was able to stabilise under Sen, Cambodia was accepted into the Association of Southeast Asian Nations (ASEAN) on 30 April 1999. Norodom Sihamoni was crowned Cambodia's king in 2004 after his father Sihanouk's abdication.

During the 1990s and 2000s, reconstruction efforts progressed which led to some political stability through a multiparty democracy under a constitutional monarchy although Sen's rule has been marred by human rights abuses and corruption. Cambodia's economy grew rapidly in the 2000s and 2010s, and it received considerable investment and infrastructure development support from China as part of its Belt and Road Initiative.

A UN-backed war crimes tribunal, the Khmer Rouge Tribunal sought out to investigate crimes committed during the Democratic Kampuchea period and prosecute its leaders. Hun Sen has opposed extensive trials or investigations of former Khmer Rouge officials. In July 2010, Kang Kek Iew was the first Khmer Rouge member found guilty of war crimes and crimes against humanity in his role as the former commandant of the S21 extermination camp and he was sentenced to life in prison.

After the 2013 Cambodian general election, allegations of voter fraud from opposition party Cambodia National Rescue Party led to widespread anti-government protests that continued into the following year. The protests ended after a crackdown by government forces. The Cambodia National Rescue Party was dissolved ahead of the 2018 Cambodian general election and the ruling Cambodian People's Party also enacted tighter curbs on mass media. The CPP won every seat in the National Assembly without major opposition, effectively solidifying de facto one-party rule in the country.

PM Hun Sen was one of the world's longest-serving leaders. He had been accused of crackdowns on opponents and critics. In December 2021, Hun Sen announced his support for his son Hun Manet to succeed him after the next general election in 2023. A July 2023 Human Rights Watch report showed election fraud and vote tampering in the June 2022 commune elections. In the July 2023 election, the ruling Cambodian People's Party (CPP) won by a landslide in an election, after the disqualification of a Cambodia's opposition, Candlelight Party. On 22 August 2023, Hun Manet was sworn in as the new Cambodian PM.

Cambodia has an area of 181,035 km2 (69,898 sq mi) and lies entirely within the tropics, between latitudes 10° and 15°N, and longitudes 102° and 108°E. It borders Thailand to the north and west, Laos to the northeast, and Vietnam to the east and southeast. It has a 443 km (275 mi) coastline along the Gulf of Thailand.

Cambodia's landscape is characterised by a low-lying central plain that is surrounded by uplands and low mountains and includes the Tonle Sap (Great Lake) and the upper reaches of the Mekong River delta. Extending outward from this central region are transitional plains, thinly forested and rising to elevations of about 200 m (650 ft) above sea level. In Cambodia forest cover is around 46% of the total land area, equivalent to 8,068,370 hectares (ha) of forest in 2020, down from 11,004,790 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 7,464,400 ha, and planted forest covered 603,970 ha. Of the naturally regenerating forest 4% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity). For the year 2015, 100% of the forest area was reported to be under public ownership.

To the north the Cambodian plain abuts a sandstone escarpment, which forms a southward-facing cliff stretching more than 320 km (200 mi) from west to east and rising abruptly above the plain to heights of 180–550 m (600–1,800 ft). This cliff marks the southern limit of the Dângrêk Mountains.

Flowing south through Cambodia's eastern regions is the Mekong River. East of the Mekong the transitional plains gradually merge with the eastern highlands, a region of forested mountains and high plateaus that extend into Laos and Vietnam. In southwestern Cambodia two distinct upland blocks, the Krâvanh Mountains and the Dâmrei Mountains, form another highland region that covers much of the land area between the Tonle Sap and the Gulf of Thailand.

In this largely uninhabited area, Phnom Aural, Cambodia's highest peak rises to an elevation of 1,813 m (5,949 ft). The southern coastal region adjoining the Gulf of Thailand is a narrow lowland strip, heavily wooded and sparsely populated, which is isolated from the central plain by the southwestern highlands.

The most distinctive geographical feature is the inundations of the Tonle Sap, measuring about 2,590 km2 (1,000 sq mi) during the dry season and expanding to about 24,605 km2 (9,500 sq mi) during the rainy season. This densely populated plain, which is devoted to wet rice cultivation, is the heartland of Cambodia. Much of this area has been designated as a biosphere reserve.

Cambodia's climate, like that of the rest of Southeast Asia, is dominated by monsoons, which are known as tropical wet and dry because of the distinctly marked seasonal differences.

Cambodia has a temperature range from 21 to 35 °C (70 to 95 °F) and experiences tropical monsoons. Southwest monsoons blow inland bringing moisture-laden winds from the Gulf of Thailand and Indian Ocean from May to October. The northeast monsoon ushers in the dry season, which lasts from November to April. The country experiences the heaviest precipitation from September to October with the driest period occurring from January to February.

According to the International Development Research Centre and The United Nations, Cambodia is considered Southeast Asia's most vulnerable country to the effects of climate change, alongside the Philippines. Nearly all provinces in Cambodia are affected by climate change. Rural coastal populations are particularly at risk. Shortages of clean water, extreme flooding, mudslides, higher sea levels and potentially destructive storms are of particular concern, according to the Cambodia Climate Change Alliance. Climate change has also had a major impact on water levels, ecology and productivity of the Tonlé Sap in recent years, affecting the food security and agriculture of a large proportion of Cambodia's population.

Cambodia has two distinct seasons. The rainy season, which runs from May to October, can see temperatures drop to 22 °C (72 °F) and is generally accompanied with high humidity. The dry season lasts from November to April when temperatures can rise up to 40 °C (104 °F) around April. Disastrous flooding occurred in 2001 and again in 2002, with some degree of flooding almost every year. Severe flooding also affected 17 provinces in Cambodia during the 2020 Pacific typhoon season.

Cambodia's biodiversity is largely founded on its seasonal tropical forests, containing some 180 recorded tree species, and riparian ecosystems. There are 212 mammal species, 536 bird species, 240 reptile species, 850 freshwater fish species (Tonle Sap Lake area), and 435 marine fish species recorded by science. Much of this biodiversity is contained around the Tonle Sap Lake and the surrounding biosphere.

The Tonle Sap Biosphere Reserve is a reserve surrounding the Tonle Sap lake. It encompasses the lake and nine provinces: Kampong Thom, Siem Reap, Battambang, Pursat, Kampong Chhnang, Banteay Meanchey, Pailin, Oddar Meanchey and Preah Vihear. In 1997, it was successfully nominated as a UNESCO Biosphere Reserve. Other key habitats include the evergreen and dry Dipterocarp forests of Mondolkiri province, protected by Keo Seima Wildlife Sanctuary, Phnom Prich Wildlife Sanctuary, and Srepok Wildlife Sanctuary, as well as Ratanakiri province, and the Cardamom Mountains ecosystem, including Preah Monivong National Park, Botum-Sakor National Park, and the Phnom Aural Wildlife Sanctuary and Phnom Samkos Wildlife Sanctuary.

The Worldwide Fund for Nature recognises six distinct terrestrial ecoregions in Cambodia – the Cardamom Mountains rain forests, Central Indochina dry forest, Southeast Indochina dry evergreen forest, Southern Annamite Range tropical forest, Tonle Sap freshwater swamp forest, and Tonle Sap-Mekong peat swamp forest.

The rate of deforestation in Cambodia is one of the highest in the world and it is often perceived as the most destructive, singular environmental issue in the country. Cambodia's primary forest cover fell from over 70% in 1969 to just 3.1% in 2007. Since 2007, less than 3,220 km2 (1,243 sq mi) of primary forest remain with the result that the future sustainability of the forest reserves of Cambodia is under severe threat. In 2010–2015, the annual rate of deforestation was 1.3%. The environmental degradation also includes national parks and wildlife sanctuaries on a large scale and many endangered and endemic species are now threatened with extinction due to loss of habitats. Reasons for the deforestation in Cambodia range from opportunistic illegal loggings to large scale clearings from big construction projects and agricultural activities. The deforestation involves the local population, Cambodian businesses and authorities as well as transnational corporations from all over the world.

Plans for hydroelectric development in the Greater Mekong Subregion, by Laos in particular, pose a "real danger to the food supply of Vietnam and Cambodia. Upstream dams will imperil the fish stocks that provide the vast majority of Cambodia's protein and could also denude the Mekong River of the silt Vietnam needs for its rice basket." The rich fisheries of Tonle Sap, the largest freshwater lake in Southeast Asia, largely supply the impoverished country's protein. The lake all but disappears in the dry season and then expands massively as water flow from the Mekong backs up when the rains come. "Those fish are so important for their livelihoods, both economically and nutritionally", said Gordon Holtgrieve, a professor at the University of Washington; he points out that none of the dams that are either built or being built on the Mekong river "are pointing at good outcomes for the fisheries".

In the 2010s, the Cambodian government and educational system has increased its involvement and co-operation with both national and international environmental groups. A new National Environmental Strategy and Action Plan (NESAP) for Cambodia is to be implemented from late 2016 to 2023 and contains new ideas for how to incite a green and environmentally sustainable growth for the country.

The autonomous municipality (reach thani) and provinces (khaet) of Cambodia are first-level administrative divisions. Cambodia is divided into 25 provinces including the autonomous municipality.

Municipalities and districts are the second-level administrative divisions of Cambodia. The provinces are subdivided into 159 districts and 26 municipalities. The districts and municipalities in turn are further divided into communes (khum) and quarters (sangkat).

Cambodia is a constitutional monarchy with a unitary structure and a parliamentary form of government. The king is officially the head of state and is the symbol of unity and "perpetuity" of the nation, as defined by Cambodia's constitution. Legislative powers are shared by the executive and the bicameral Parliament of Cambodia (សភាតំណាងរាស្ត្រ, sâphéa tâmnang réastrâ), which consists of a lower house, the National Assembly (រដ្ឋសភា, rôdthâsâphéa) and an upper house, the Senate (ព្រឹទ្ធសភា, prœ̆tthôsâphéa). Members of the 125-seat National Assembly are elected through a system of proportional representation and serve for a maximum term of five years. The Senate has 62 seats, two of which are appointed by the king and two others by the National Assembly, and the rest are elected by the commune councillors from the 24 provinces of Cambodia. Senators serve six-year terms.

Officially a multiparty democracy, in reality, "the country remain[ed] a one-party state dominated by the Cambodian People's Party and PM Hun Sen, a recast Khmer Rouge official in power since 1985. The open doors to new investment during his reign have yielded the most access to a coterie of cronies of his and his wife, Bun Rany", according to Megha Bahree, a writer on Forbes. Cambodia's government has been described by Human Rights Watch's Southeast Asian director, David Roberts, as a "relatively authoritarian coalition via a superficial democracy".

PM Hun Sen vowed to rule until he turned 74. His government was regularly accused of ignoring human rights and suppressing political dissent. The 2013 election results were disputed by the opposition, leading to demonstrations in the capital. Demonstrators were injured and killed in Phnom Penh where a reported 20,000 protesters gathered, with some clashing with riot police. From a humble farming background, Hun Sen was 33 when he took power in 1985, and was by some considered a long-ruling dictator. Hun Sen was succeeded by his son Hun Manet as PM in August 2023 following an election that was deemed by independent and foreign media and politicians to be neither free nor fair. Hun Sen remains the de facto ruler of Cambodia through his continued leadership of the Cambodian People's Party. Following the 2024 Senate election, Hun Sen became president of the Senate, a role which gives him the power to sign off on laws in the King's absence.

Since the 2017 crackdowns on political dissent and free press, Cambodia has been described as a de facto one-party state.

On 14 March 2018, the UN expert on the human rights situation in Cambodia "expressed serious concerns about restrictions on the media, freedom of expression and political participation ahead of a national election in July". Some critics of the government have been arrested for allegedly spreading fake news about the COVID-19 pandemic in Cambodia.

Cambodia has established diplomatic relations with other countries; the government reports 20 embassies in the country including some of its Asian neighbours and those of "important players" during the Paris peace negotiations, including the U.S., Australia, Canada, China, the EU, Japan, and Russia.

While the violent ruptures of the 1970s and 1980s have passed, several border disputes between Cambodia and its neighbours persist. There are disagreements over some offshore islands and sections of the boundary with Vietnam and undefined maritime boundaries. Cambodia and Thailand have border disputes, with troops clashing over land immediately adjacent to the temple of Preah Vihear in particular, leading to a deterioration in relations. Most of the territory belongs to Cambodia, and a combination of Thailand disrespecting international law, Thai troops upbuild in the area and lack of resources for the Cambodian military have left the situation unsettled since 1962.

Cambodia and China have cultivated ties in the 2010s. A Chinese company with the support of the People's Liberation Army built a deep-water seaport along 90 km (56 mi) stretch of Cambodian coastline of the Gulf of Thailand in Koh Kong province; the port is sufficiently deep to be used by cruise ships, bulk carriers or warships. Cambodia's diplomatic support has been invaluable to Beijing's effort to claim disputed areas in the South China Sea. Because Cambodia is a member of ASEAN, and because under ASEAN rules "the objections of one member can thwart any group initiative", Cambodia is diplomatically useful to China as a counterweight to southeast Asian nations that have closer ties to the United States.

Cambodia is the 70th most peaceful country in the world, according to the 2024 Global Peace Index.
