🇰🇭 Cambodia

The cave of Laang Spean is regarded as the most ancient archaeological site in Cambodia, with lower layers yielding radiocarbon dates around 6000 BC. Upper layers show the transition to the Neolithic and contain the earliest dated earthenware ceramics found in the country.

Iron was worked by about 500 BC, with supporting evidence from the Khorat Plateau and Iron Age settlements found beneath Angkorian temples such as Baksei Chamkrong. Burials indicate improved food availability, trade and an emerging social structure and labour organisation.

Glass beads from the Phum Snay site in the north-west and the Prohear site in the south-east indicate two main trading networks separated in time and space. Archaeologists infer a shift from one network to the other around the 2nd to 4th century, probably reflecting changes in socio-political power.

During the 3rd, 4th and 5th centuries the Indianised polities of Funan and its successor Chenla formed in what became Cambodia and south-western Vietnam. Over more than two millennia the region absorbed Indian influences and transmitted them onward to the civilisations of Thailand and Laos.

In 802 Jayavarman II declared independence from Java and proclaimed himself universal monarch, uniting the warring Khmer princes of Chenla under the name Kambuja and instituting the cult of the God-king. The empire he founded dominated mainland Southeast Asia from the 9th to the 15th centuries and remains the foundation of Cambodian national identity; King Suryavarman II built Angkor Wat as a state temple in the early 12th century, the largest religious monument in the world.

Most Cambodians consider themselves Khmers, descendants of the Angkor Empire that extended over much of Southeast Asia and peaked between the 10th and 13th centuries. Attacks by the Thai and Cham from present-day Vietnam weakened the empire, ushering in a long period of decline.

The Angkor empire was attacked by Kublai Khan's Mongol forces during the reign of Jayavarman VIII. The king was able to purchase peace, sparing the empire the fate of other Asian states overrun by the Mongols.

Missionaries from Sri Lanka, following earlier efforts in the 1190s, spread Theravada Buddhism through Southeast Asia. The religion gradually displaced Hinduism and Mahayana Buddhism as the popular faith of Angkor, reshaping Khmer religious and social life.

On taking power in 1295, Indravarman III elevated Theravada Buddhism from popular faith to state religion. This completed the religious transformation of the Khmer Empire away from the Hindu-Devaraja model.

The Siamese army's capture of the city weakened the Khmer Empire, which had already been in decline, and the royal court eventually settled near present-day Phnom Penh. Angkor was gradually abandoned, though its temples remained sites of religious pilgrimage.

Following the abandonment of Angkor the capital was eventually relocated to Longvek, which prospered as an integral part of the 16th-century Asian maritime trade network. The shift reoriented the kingdom from inland agrarian empire towards riverine and maritime commerce.

Pigafetta cited the kingdom as Camogia in his Relazione del primo viaggio intorno al mondo, written 1524–1525. The reference shows that the name Cambodia was already circulating in Europe by the early 16th century.

Rivalry with the Ayutthaya Kingdom produced repeated conflicts, culminating in the Siamese capture of Longvek in 1594. The fall of the capital deepened Cambodia's slide into vassalage between stronger neighbours.

Siamese and Vietnamese dominance intensified through the 17th and 18th centuries, forcing frequent displacements of the Khmer seat of power. Both powers alternately demanded subservience and tribute from the Cambodian court, which lost effective sovereignty.

The Mekong Delta, once part of the Khmer Empire, came under Vietnamese control in 1698, decades after King Chey Chettha II had permitted Vietnamese settlement there. The permanent loss of the delta remains a foundational grievance in Cambodian-Vietnamese relations.

King Norodom signed the treaty placing the kingdom under French protection, ending a period in which Cambodia had been squeezed between more powerful Thai and Vietnamese neighbours. Cambodia was later incorporated into French Indochina alongside Vietnam and Laos.

Between 1874 and 1962 Cambodia's recorded population rose from about 946,000 to 5.7 million. Colonial peace, ended slave-raiding and public health measures underpinned a demographic recovery from the post-Angkorian nadir.

Excavation at Samrong Sen, not far from the former capital of Oudong, began in 1875. It became one of the earliest systematically studied prehistoric sites in Cambodia, though its dating remains uncertain.

After King Norodom's death in 1904 the French manipulated the succession, placing his brother Sisowath on the throne. The episode demonstrated that royal legitimacy had become an instrument of colonial control.

The colonial administration carried out the first census in 1921, establishing modern demographic record-keeping. A further census followed in 1962.

On the death of King Monivong in 1941 the French bypassed his son Monireth as too independently minded and installed Monivong's maternal grandson Norodom Sihanouk. The French expected Sihanouk to be easily controlled; he instead dominated Cambodian politics for half a century.

Japanese forces occupied the kingdom from 1941 to 1945, and in 1945 Cambodia existed briefly as the puppet Kingdom of Kampuchea. The interruption of French authority exposed the fragility of colonial rule and encouraged nationalist demands.

His diplomatic campaign achieved full sovereignty on 9 November 1953. He later abdicated to enter politics directly, dominating Cambodian public life for the next two decades.

In 1955 Sihanouk gave up the throne to his father in order to contest elections, and became prime minister. The manoeuvre fused monarchical legitimacy with electoral politics and entrenched his personal dominance.

When his father died in 1960 Sihanouk resumed the position of head of state, taking the title of prince rather than king. The arrangement preserved his supremacy over Cambodian political life into the Vietnam War years.

As the Vietnam War intensified Sihanouk proclaimed neutrality but allowed Vietnamese communists to use Cambodian territory as sanctuary and supply route to South Vietnam. The double game drew Cambodia into the wider conflict and eroded its internal stability.

Although most of the disputed territory was awarded to Cambodia, Thai disregard of international law, a Thai troop build-up and Cambodia's limited military resources have kept the situation unresolved since 1962. Border disputes with neighbours persist as a standing security concern.

Sihanouk told Washington Post journalist Stanley Karnow in December 1967 that he would not object to American bombing of Vietnamese communist sanctuaries provided Cambodians were not killed, a message repeated to Chester Bowles in January 1968. Publicly he denounced the strikes, and in March 1968 appealed to international media to condemn all bombing of Cambodian territory. The bombing continued regardless.

Primary forest fell from more than 70 per cent of the country in 1969 to just 3.1 per cent by 2007, leaving under 3,220 square kilometres. Total forest cover also declined from 11.0 million hectares in 1990 to 8.07 million in 2020, with deforestation running at 1.3 per cent a year in 2010–2015.

While Sihanouk was visiting Beijing in 1970 he was deposed by a coup that installed a US-aligned regime demanding Vietnamese communist withdrawal. Sihanouk urged his followers to resist, hastening full-scale civil war and lending the Khmer Rouge royal legitimacy.

Soviet archival documents uncovered after 1991 show the 1970 North Vietnamese attempt to overrun Cambodia was made at the explicit request of the Khmer Rouge and negotiated by Nuon Chea. NVA units overran Cambodian army positions while Communist Party of Kampuchea forces attacked lines of communication.

In response to the North Vietnamese invasion, Nixon announced that US and South Vietnamese ground forces had entered Cambodia to destroy NVA base areas. The incursion internationalised the Cambodian war and further destabilised the Khmer Republic.

Unexploded mines have been blamed for more than 60,000 civilian deaths and thousands more maimed since 1970, with 44,630 injuries recorded between 1979 and 2013. Casualties fell from 800 in 2005 to 111 in 2013, and Cambodia was expected to be mine-free by 2025, though one in 290 people is an amputee.

After taking Phnom Penh on 17 April 1975, the Khmer Rouge under Pol Pot emptied the cities and enforced forced agrarian labour. Estimates of those killed range from one to three million, most commonly cited as around two million or a quarter of a population of some 8 million, giving rise to the term Killing Fields and the notoriety of Tuol Sleng prison. Cham Muslims lost as much as half their population, professionals were systematically executed, hundreds of thousands fled into Thailand, and the regime destroyed 95 per cent of Buddhist temples and vast amounts of Khmer architecture.

An offensive launched on New Year's Day 1975 pinned Republican forces around Phnom Penh while CPK units seized fire bases on the lower Mekong resupply route. A US-funded airlift of ammunition and rice ended when Congress refused further aid, sealing the Republic's collapse.

Singers of the 1960s and 1970s such as those of the Sinn Sisamouth era were murdered, starved or worked to death during the revolution. Exiled artists such as Keo Sarath carried on the repertoire from the 1980s, and kantrum rose in popularity in the 1980s and 1990s.

By 1978 judges and lawyers had been executed as class enemies and the legal system was destroyed, with only six to twelve legal professionals surviving in the country. The annihilation of the legal profession crippled Cambodian state capacity for a generation.

Hanoi's forces captured Phnom Penh on 7 January 1979, ending almost four years of Khmer Rouge rule, though the group continued a guerrilla insurgency from remote areas for almost two more decades. Vietnamese troops remained in Cambodia until 1989.

The PRK was established under the Kampuchean People's Revolutionary Party, a body created by the Vietnamese in 1951, and led by Khmer Rouge defectors who had fled Pol Pot's purges. It was wholly beholden to the occupying Vietnamese army, directed by Hanoi's ambassador, and armed by Vietnam and the Soviet Union.

The CGDK united the Khmer Rouge, a royalist faction led by Sihanouk and the Khmer People's National Liberation Front, and its credentials were recognised by the United Nations. Vietnam's refusal to withdraw meanwhile brought economic sanctions on the Phnom Penh government.

Peace efforts begun in Paris in 1989 under the State of Cambodia culminated in the Paris Comprehensive Peace Settlement of October 1991, ending nearly thirteen years of civil war. The accords mandated democratic elections and a ceasefire and gave the UN a mandate to enforce it and to handle refugees and disarmament through the United Nations Transitional Authority in Cambodia, though the ceasefire was not fully respected by the Khmer Rouge.

The listing recognised the temple complex, including Angkor Wat, as one of the world's most significant archaeological sites. It was placed simultaneously on the List of World Heritage in Danger owing to looting and war damage, and removed from that list in 2004.

UNTAC coordinated Cambodia's first post-war election in 1993, held under the transitional UN administration established by the 1991 Paris Peace Agreements. FUNCINPEC under Prince Norodom Ranariddh won a hung parliament, and after the Cambodian People's Party threatened to secede part of the country the two formed a coalition with Ranariddh and Hun Sen as co-prime ministers. Norodom Sihanouk was reinstated as king and head of state, marking the formal end of Cambodia's civil conflict.

Since 1993 English has increasingly displaced French in Cambodian international relations and on postage stamps, and it replaced French on the currency from 2002. The shift marked reorientation away from the colonial metropole towards global and regional networks.

Lawyers did not reappear in Cambodia until the Bar Association was created in 1995, following the Khmer Rouge destruction of the legal profession. Its founding began the reconstruction of an independent legal capacity.

Average life expectancy rose from 55 years in 1995 to 75 in 2021. The gain reflects post-conflict reconstruction of health services and rising incomes.

Fighting between the coalition partners in 1997 brought down the first coalition government, but a second round of national elections in 1998 led to the formation of another coalition and renewed political stability.

Tom Andrews visited Cambodia from 20 to 31 July 2026, meeting government officials and civil society. He said he was encouraged by the government's cooperation but remained concerned about detentions for exercising political rights and reports that some officials remained linked to scam operations.

The revision, published after an Article IV mission concluded on 7 July 2026, cited rising energy prices, trade uncertainty and a tourism sector weakened by the reputational damage of online scam compounds. Inflation was projected to average 5.6 per cent over the year.

The prime minister's three-day visit from 15 to 17 July 2026 included talks with Xi and Premier Li Qiang, who called for deeper cooperation under their Diamond Hexagon framework. The two sides also discussed a joint mechanism to tackle cross-border scam and smuggling networks.

The law took effect on 23 May 2026, requiring men aged 18 to 25 to serve, and followed the previous year's border fighting with Thailand. Officials said it was intended to expand the reserve force available for national defence.

The pardon, granted on 25 May 2026, freed the former Cambodia National Rescue Party leader who had been convicted in 2023 of colluding with foreign powers. Fellow opposition figure Sun Chanthy had received a similar pardon in February.

The ceremony in Takeo province on 11 April 2026 advanced the $1.2 billion waterway linking the Mekong River to the coast, which is 51 per cent Cambodian-owned and 49 per cent Chinese-owned. Compensation disputes with affected farmers had delayed construction on the first section.

The Prince Group founder, indicted by United States prosecutors over an alleged multibillion-dollar cyber-fraud and trafficking empire, was handed to Chinese authorities in early January 2026. The National Bank of Cambodia subsequently ordered the liquidation of Prince Bank, which he had founded.

The department sought forfeiture of approximately 127,271 bitcoin in a case alleging that Chen Zhi, founder and chairman of the Prince Holding Group, directed forced-labour scam compounds in Cambodia. The action exposed the scale of illicit capital tied to Cambodian-based criminal enterprises.

Prime Minister Hun Manet led the opening ceremony on 20 October 2025 for the $2 billion facility, built to replace the capital's ageing airport and expand tourism capacity. The airport opened despite the border conflict with Thailand disrupting cross-border travel elsewhere.

The 26 October 2025 accord followed three months of fighting that had displaced more than half a million people and killed more than 100. Thailand held most captured Cambodian soldiers until releasing the last of them on 31 December.

The rate, agreed on 17 September 2025 after rounds of negotiation between unions, employers and the government, marked a $2 rise on 2025. Garment, footwear and travel-goods exports remained one of Cambodia's largest sources of foreign earnings.

Work on the canal officially began in August 2024, with excavation for the second phase under way as of late 2025. The waterway is intended to reduce dependence on foreign ports for Cambodian trade.

Following the 2024 Senate election Hun Sen assumed its presidency, a post that empowers him to sign legislation in the king's absence. The move preserved his direct constitutional authority after leaving the premiership.

The CPP swept the July 2023 election following the exclusion of the opposition Candlelight Party, in a contest independent and foreign observers judged neither free nor fair. A Human Rights Watch report that month also documented fraud and vote tampering in the June 2022 commune elections.

Arrivals topped 5.4 million in 2023 according to the Ministry of Tourism, continuing growth in the stable period since the 1993 UNTAC elections. Receipts had already exceeded US$4.4 billion in 2018, nearly a tenth of gross national product, with Chinese visitors the largest group and casino numbers rising from 57 in 2014 to 150.

The transition, completed on 22 August 2023, followed a general election in July that the ruling Cambodian People's Party won after the main opposition party was barred from standing. Hun Sen remained influential as president of the Senate and head of the ruling party.

In December 2021 Hun Sen declared support for Hun Manet to succeed him after the 2023 general election. The announcement formalised a hereditary transfer of power within the CPP state.

From the early 2020s guarded compounds in Cambodia hosted industrial-scale online fraud linked to trafficking, forced criminality and forced labour. A 2023 UN human rights report estimated around 100,000 people were held in such operations, and a 2025 Amnesty International report identified at least 53 compounds and documented slavery and torture, alleging official complicity that the government denied.

A 2019 directive barred the Finance Ministry from issuing further online gambling licences, allowing existing holders to operate only until expiry, after more than 150 had been issued. The policy shift preceded the growth of unlicensed online criminal operations.

With the CNRP dissolved and tighter curbs imposed on mass media, the CPP took all seats at the 2018 general election. The result solidified de facto one-party rule, and in March 2018 a UN human rights expert publicly criticised the restrictions on media and political participation.

In 2017 the Supreme Court disbanded the main opposition party amid a wider crackdown on political dissent and the free press. The ruling cleared the path to a de facto one-party state.

The law was passed in April 2016, a year after the ITUC Global Rights Index placed Cambodia among the worst countries for organised labour with no guarantee of rights. It regulated union activity in the country's dominant export industry.

NESAP was to run from late 2016 to 2023 and set out ideas for green, environmentally sustainable growth. Its drafting followed increased cooperation during the 2010s between government, the education system and national and international environmental groups.

The Master Plan for 2014–2020 was launched in December 2014 after a two-year process supported by the Korea International Cooperation Agency. It represented Cambodia's first comprehensive attempt to plan research and innovation capacity.

Allegations of fraud after the 2013 general election brought some 20,000 demonstrators onto the streets of Phnom Penh, with clashes, injuries and deaths, and journalists reporting deliberate attacks by police and plain-clothes men in September 2013. The protests continued into the following year before being ended by a government crackdown.

Exports rose 8 per cent over 2011 to US$4.61 billion in 2012, and in the first half of 2013 the garment sector alone reported exports worth US$1.56 billion. Garment manufacturing became the mainstay of the post-conflict export economy.

Credit Bureau Cambodia was set up in 2012 with direct regulatory supervision by the central bank. It gave the financial system a formal credit-information infrastructure supporting rapid lending growth.

The UN-backed tribunal found the former commandant of the S21 extermination camp guilty and sentenced him to life imprisonment, the first Khmer Rouge member so convicted. Hun Sen has opposed extensive further trials or investigations of former Khmer Rouge officials.

The 2010 law offered no protection to whistle-blowers, who can be jailed for up to six months if they report corruption that cannot be proven. The statute illustrated the limits of the government's anti-corruption commitment.

Using satellite photographs and other modern techniques, researchers concluded in 2007 that Angkor's urban sprawl covered about 2,980 square kilometres. The city could have supported a population of up to one million people, recasting understanding of Khmer state capacity.

Local elections in April 2007 saw little of the pre-election violence of earlier polls, national elections in July 2008 were relatively peaceful, and commune council elections in June 2012 passed off calmly, consolidating political stability.

The Extraordinary Chambers in the Courts of Cambodia, supported by international assistance, has tried some surviving Khmer Rouge leaders for crimes against humanity while others await trial.

Deposits found beneath Cambodian territorial waters in 2005 offer significant potential but remain mostly untapped. Territorial disputes with Thailand are part of the reason exploitation has stalled.

Sihanouk abdicated in October 2004 and Prince Norodom Sihamoni was selected to succeed him.

Donors pledged US$504 million in 2004, while the Asian Development Bank alone has supplied US$850 million in loans, grants and technical assistance. ADB money also funded a US$141 million project to revive the two rail lines and link Cambodia with Bangkok and Ho Chi Minh City.

The July 2003 elections were relatively peaceful, but it took a year of negotiations between contending political parties before a coalition government was formed in 2004.

Severe floods struck in 2001 and again in 2002, with some degree of flooding recurring almost every year. Seventeen provinces were affected during the 2020 Pacific typhoon season, underlining chronic exposure to monsoon and storm flooding.

Created in 2001 as a partnership between the ILO and the IFC, the programme monitored labour conditions in the garment sector on which Cambodian exports depend. Its advisory committee met in Phnom Penh in May 2018 to shape recommendations from an independent mid-term evaluation.

Cambodia's economy grew rapidly through the 2000s and 2010s with considerable Chinese investment and infrastructure support under the Belt and Road Initiative. Cambodia and China cultivated close political ties during the 2010s, reshaping the country's external alignment.

The fertility rate fell from 4.0 children per woman in 2000 to 2.5 in 2018, while infant mortality dropped from 86 per 1,000 live births in 1998 to 24 in 2018. As of 2010 half the population was younger than 22, giving Cambodia a pronounced youth bulge.

Cambodia joined the Association of Southeast Asian Nations on 30 April 1999 once its government had stabilised under Hun Sen. Membership ended a decade of diplomatic isolation and integrated the country into regional economic and political structures.

The committee, in place since 1999, provided the first cross-government structure for science policy. It was followed by a 2010 Ministry of Education policy on research development in the education sector.

The last elements of the Khmer Rouge gave up in early 1999, finally ending the movement's insurgency.

Civil conflict and instability after the 1962 census left Cambodia without a national enumeration until 1998. The gap reflected the near-total collapse of state administrative capacity during the war and Khmer Rouge years.

Fearing the growing strength of his co-prime minister Prince Norodom Ranariddh, Hun Sen used the army to purge him and his supporters and expel other parties from government. Fighting between the two men's forces in Phnom Penh in July 1997 left Hun Sen as sole prime minister, ending the power-sharing arrangement formed after the 1993 election; Ranariddh went into exile before returning to Cambodian politics the following year, while power was consolidated in the Cambodian People's Party.

The successful nomination in 1997 gave international recognition to the lake system that underpins Cambodian fisheries and biodiversity. The Tonle Sap expands from about 2,590 square kilometres in the dry season to some 24,605 in the rainy season.
