On Christmas Day of 1978, a joint Vietnamese and Cambodian Kampuchean United Front for National Salvation entered Khmer Rouge controlled Kampuchea (Cambodia). Not long after new year’s day, the Khmer Rouge had fallen and their genocide, which had killed up to 30% of the population, was over. In Phnom Penh the streets stood silent, lined with derelict buildings and devastated infrastructure. In the countryside, croplands and irrigation channels had been decimated. There was almost nobody left alive in the country who hadn’t been internally displaced. The population of 5 million was served by only around 46 doctors. Today, much light has been shed on the crimes of the Khmer Rouge. However, the story of their overthrow, and the decade-long ambitious project of socialist reconstruction that followed, has largely been lost to history. While that socialist project was rapidly and systematically dismantled by Western market forces via The United Nations.
Devastation
In the dying days of 1978 the scale of devastation found by the Vietnamese and Khmer liberators defied comprehension. However, it was a landscape not entirely unfamiliar. Vietnam had, of course, faced a mass destruction campaign by the U.S and its allies over the previous two decades– a campaign they themselves were only just recovering from. Vietnam’s own recovery and reconciliation served as a blueprint for socialist state reconstruction, one developed by Vietnamese revolutionaries, as well as Cambodian socialists, peasants and workers, one which would begin to rebuild the state and social apparatuses after Year Zero.
The following year the People’s Republic of Kampuchea (PRK) was established in Phnom Penh. A Khmer-language PRK radio broadcast from March 1979 pleaded with citizens: “Brothers and sisters, return to your home villages. The Vietnamese comrades are bringing rice seeds and medicine. The Pol Pot time is over.”
Engineering teams, working around the clock, restored Phnom Penh’s water and electricity within weeks; medical teams vaccinated over two million Cambodians against polio and other diseases and agricultural collectives began to revive food production. Assistance from Hanoi’s administration and the hard work of the Cambodian people laid foundations for a new generation of Cambodian society, revolutionary teachers, doctors and civil servants, many trained in Vietnam, who began rebuilding their shattered society and proletarian state apparatuses in Cambodia, modelled on Vietnam’s– very successful –socialist system but adapted to Cambodian realities. The state prioritised basic needs, free healthcare, food rationing, land redistribution to peasants and a public education system rebuilt from scratch, much of which thanks to efforts from grassroots Krom Samaki (solidarity groups) which ran on an economy of solidarity.
Internationally The PRK immediately found itself at the center of international controversy. While the state was recognised by the Soviet bloc and a handful of non-aligned states, Western powers and China vehemently opposed its legitimacy, instead continuing to recognise the exiled Khmer Rouge as Cambodia’s rightful representatives at the United Nations. This diplomatic isolation stemmed from broader strategic calculations, the United States saw Vietnam as a Soviet proxy and sought to punish Hanoi for its re-unification, while China viewed the PRK as an unacceptable expansion of Vietnamese influence in Indochina.
Vietnam saw itself as fulfilling an internationalist duty by removing the genocidal Khmer Rouge, the intervention, however, was framed by The West as an act of aggression. Soviet support for the PRK provided crucial economic and military aid, but was presented as “evidence” in ASEAN and Western capitals that Cambodia had become a proxy Soviet satellite. Meanwhile, Thailand became a frontline state in the resistance to the PRK, facilitating Khmer Rouge remnants operating from border camps and serving as a key conduit for American military support to the rabid Khmer Rouge insurgency.
Domestically, the administrative backbone of the PRK was the Cadre system. Unlike the fanatical cadres of the Pol Pot regime, PRK cadres were often pragmatists, typically made up of former Khmer Rouge defectors or Vietnamese-trained Khmer revolutionaries. They sought to mitigate the immediate crisis of famine and the collapsed social infrastructure by ensuring socialist policies, while simultaneously organising a de-Khmer Rouge’ification program.
Agriculture
Following the liberation, the most pressing issue facing the PRK was feeding the people. Under the Khmer Rouge, all land was de facto state-controlled, and farmers were reduced to slave laborers in giant work brigades. Private farming was punishable by death, and rice production plummeted due to mismanagement and brutality by the overseers. When the PRK took power in 1979, they inherited abandoned fields with the ever present threat of landmines or unexploded ordinances– both from the Khmer Rouge and The American bombers. Vietnam, which had implemented its own “Land to the Tiller” reforms after reunification in 1975, advised Cambodia on a modified approach.
Many farmers were encouraged to go back to their original villages where they were allocated land for village farming cooperatives. Unlike the Khmer Rouge’s mass work brigades, PRK farmers worked communally while keeping small private family plots. Vietnam also provided seeds, livestock, and tools to restart farming.
Villages were organised along the lines of semi-autonomous “Solidarity Groups” (Krom Samaki), typically consisting of 10 to 20 households, who were allocated usage rights to village land. Mirrored after Vietnam’s own “collective contract system” (khoán) Solidarity Groups aimed for self-sufficiency and flexibility, depending on the harvest, a certain quota of surplus, between 20% & 30%, was procured by the state at a fixed price for redistribution as rations, while what remained was sold on in the re-opened markets. Despite all the challenges, Vietnamese reports indicate that by 1982, helping restore Cambodia’s rice production to 60% of pre-war levels.
Education
In education The PRK faced an almost unimaginable challenge in restarting schooling in a country where the Khmer Rouge had executed 80% of teachers, destroyed schools, and banned formal education entirely. By 1979 Cambodia’s intellectual infrastructure had been nearly erased. Literacy rates likely plummeted from pre-war levels of around 60% in 1974 to below 20% in 1978. UNESCO later classified this as one of history’s most severe literacy collapses.
With so few educators left, the PRK implemented emergency teacher training programs. Young people with even minimal schooling were recruited and given crash courses. Many instructors were effectively students themselves, learning material just days before teaching it. PRK teachers occupied a unique position; part civil servant, part ideological cadre, often receiving only rations from the state but provided with housing and paid in kind by the communities they were teaching in.
In the early days, education was improvised in whatever spaces were available, under trees, in pagodas, or village communal centres. The PRK’s Ministry of Education, established in 1980, had to recreate an entire system from scratch. Vocational training was prioritised, particularly in agriculture and basic mechanics, to meet immediate reconstruction needs.
Much of the curriculum was adapted from Vietnam’s, with an emphasis on socialism, materialism and dialectical reasoning. While for more advanced technical subjects Vietnamese and Soviet educators stepped in. By 1985, enrollment reached 1.5 million students – a figure that would have been unimaginable six years earlier at a time when public education was at total collapse, while literacy rates rose dramatically from an estimated 20% in 1978 to around 50% by 1989.
Healthcare
Most hospitals and clinics had been gutted, equipment looted and their doctors killed. Diseases like Malaria, dysentery, tuberculosis were rampant, as well as war injuries and the ongoing threat of the Khmer Rouge insurgency and landmine pocked fields.
Vietnam immediately dispatched 1,200 medical personnel (doctors, nurses, pharmacists, etc.) to Cambodia in 1979-1980. Vietnamese personnel conducted over 2 million vaccinations between 1979-1984, while establishing 25 hospitals in the period aided by clinicians and trainers from Cuba, East Germany, Hungary, Poland and the USSR.
Cambodian medics were given crash-course training; teenagers became medical cadres after 3–6 months of training– similar to the “barefoot doctors” model established in China, Laos and Vietnam. Many were chosen for their political reliability or revolutionary zeal, already by 1980 7000 health cadres/medics had been trained. By 81 the number of medical cadres (including doctors) had increased to 11,231, however, only 35 were university trained, and 18 of them were freshly graduated that year. With such little medical materials public healthcare was focused on prevention of diseases as the only means of triage available. Developments in public health were slow and frustrating for administrators, the lack of qualified staff and the restrictions imposed on it by the significant shortage of drugs and other medical supplies meant that further developments were severely restricted throughout the whole period of the PRK.
The local medical cadres or barefoot doctors operated as mobile clinics, with many travelling by foot or bicycle between villages with rudimentary supplies, over the next decade there would be a sharp rise in pregnancies as familial life returned to the country. These doctors would deliver the first of a new generation of babies, vaccinate them and often go on to provide localised training themselves. Much like teachers these doctors were often paid in kind by communities, surviving off of an economy of solidarity rather than wages.
Economy
This economy of solidarity was essential for The PRK’s survival. Blending wartime rationing, Vietnamese/Soviet aid, improvised local barter networks and pure social solidarity. This was not the true command economy the state hoped to develop, but a patchwork of necessity, whereby from each according to their ability to each according to their need, on the communal level, overrode official policies.
The PRK leadership called on party cadres to encourage this solidarity economy:
“Raise awareness of self-reliance, supporting oneself. Raise awareness of mutual respect and helping to care for each other. Share food together; save each other from disaster in this time of shortages. As well as this, we must take every possibility of assistance from the international community. We must organise in order to ensure that the distribution of aid gets to the people and is not spoilt or lost or falls into the hands of the enemy. The distribution must ensure justice and appropriateness. Strive to get it to the revolutionary families, the families of cadres, and those who have no means of support like the orphans.”
A shadow economy of trust and reciprocity emerged. Urbanites traded spare clothing or jewelry for farmers’ vegetables; teachers accepted bags of rice as payment from students’ families; Vietnamese soldiers bartered cigarettes for fresh fish. The PRK framed this as state supported “socialist mutual aid,” in practice it was a society running on care and ingenuity. This informal communal social solidarity, more than the PRK’s lofty socialist rhetoric, kept communities alive.
Social
As soon as the PRK was instituted the Commission for Social Action was formed, tasked with restoring some kind of social order following the dismantling of social infrastructure by the Khmer Rouge. The elderly who were unable to care for themselves were placed with families, ideally reunited with their existing families, though of course in many cases this was not possible. The same project was also undertaken to house and care for disabled war veterans, many of whom were amputees or suffered other severe disabilities.
The Revolutionary Women’s Association of Kampuchea was established and partnered with The Vietnam Women’s Union. The initial triage program organised by these groups was to care for many thousands of orphans. Cambodian provinces were “twinned” with Vietnamese provinces and orphans were collectively cared for by the associations. Other socialist countries provided long-term assistance, particularly Hungary which built and resourced the Kampuchea-Hungary Friendship Orphanages.
Under the Khmer Rouge Buddhism had been completely banned. The PRK began to restore the practice in line with the Laos model being developed after their respective revolution in 1975. This was called “solidarity Buddhism, without sects”, an implicit reference to the monarchical Buddhist sects that had existed alongside the monarchy prior to the Khmer Rouge. Temples were consecrated and like the rest of the country engaged in solidarity work, taking in orphans, establishing literacy programs and caring for the disabled.
Even amidst the despair in the immediate aftermath of the liberation an Arts & Culture institute was established in 1980. They were tasked with the mammoth project of collecting and archiving what was left of Cambodia’s once thriving art and music scene, once known for its pop culture, musicians like Sinn Sisamouth and Ros Serey Sothea had vanished in the genocide. The institute’s work archiving its remnants remains a source of both pride and melancholy for Cambodian’s today, as artists like Sisamouth and Serey Sothea are still two of the most commonly heard singers. The mobile department made constant trips to the countryside, screening films, staging concerts and recording surviving artists’ work; they even presented their works at international film festivals. As well as these cultural pursuits the ministry was also tasked with planting crops and raising animals, (in 1981: 80 chickens, 70 ducks, 15 rabbits, one goose, one pig, two fishponds, and two shrimp ponds).
Reconciliation
When Phnom Penh was liberated in 1979, cadres invited foreign journalists and diplomats to witness first-hand the gruesome aftermath of Khmer Rouge rule, abandoned prisons like Tuol Sleng (S-21), mass graves filled with skulls, and emaciated survivors. The visits provided irrefutable evidence of genocide, countering years of Khmer Rouge denials and international skepticism, famously seen in John Pilger’s Year Zero documentary. Vietnam rightly used these revelations to justify its intervention as a humanitarian/solidarity mission. The photographic and testimonial evidence gathered by Vietnamese investigators became foundational for later war crimes tribunals, including the UN-backed trials of a handful of surviving Khmer Rouge leaders.
Domestically, The PRK embarked on an education campaign to preserve the sites of graves and educated their countrymen as to the atrocity that had taken place. The state backed the production of documentaries featuring graphic footage of mass graves and survivor interviews, which was screened in villages. Propaganda art depicted Cambodian and Vietnamese soldiers as saviors breaking chains, juxtaposed with skulls and Khmer Rouge torture scenes while state radio broadcasted survivor testimonies and lists of victims names. Public “Crime Exposing” Meetings were held in villages wherein former Khmer Rouge members (especially low-ranking ones) were forced to confess their actions and denounce the old regime. These were modeled on Cultural Revolution self-criticism sessions, and aimed at fostering a spirit of reconciliation rather than punishment.
Mass graves were exhumed with international observers present, a systematic attempt to record survivor testimonies was undertaken by Vietnamese journalists, and meticulous documentation of prison archives. The mass graves were so prevalent they began to represent a public health risk. In 1981, the leadership issued a public state concerning the treatment of bodies recovered from these graves:
“Having observed that recently some of our people, on their own account, have dug up the graves where the traitors Pol Pot, Leng Sary and Khieu Samphan killed the people so savagely, in order to search for gold for their own advantage, and have thrown the bones of those corpses to the mercy of the wind and rain;
In order to respect the memory of the corpses and as clear proof to our Khmer children/descendants in the future, and to demonstrate to our international friends the savage crimes against the gentle people of Kampuchea, whereby millions were killed so tragically in the genocidal regime;
In order to avoid contagious diseases from the remains of the corpses and all dangers to the health and well-being of the people who live nearby the graves, especially the people who live lower than the graves where seepage can enter their water supply.”
Villages where bones had already been disturbed were required to build pavilions to store the remains and any further bones uncovered in the area. Local authorities were encouraged to adopt measures to forbid the people from disturbing the graves further. By the late 80s almost every communal center in the country had pavilions publicly displaying human remains.
Vietnam’s Foreign Ministry, made compilations of survivor testimonies, prison documents, and photos of mass graves for distribution to international aid agencies and foreign governments. This forced Western governments, which had initially condemned Vietnam’s “invasion,” to gradually acknowledge the reality of the atrocities carried out by their allies in the Khmer Rouge. Vietnamese media circulated images globally of the Killing Fields’ skeletal victims, drawing comparisons to Nazi concentration camps and shifting global opinion. Though Cold War politics initially muted international response, with the U.S. and ASEAN continuing to recognise the Khmer Rouge at the UN until 1991, Vietnam’s early documentation preserved crucial evidence, such as victims names, ages, places of death etc. which overwise could have been easily destroyed.
Counterrevolution
Vietnam, having sacrificed thousands of lives to liberate Cambodia, faced relentless Western retaliation. The US-led embargo, enforced with UN complicity, strangled Vietnam’s economy and isolated it diplomatically. While the West invoked “human rights,” it imposed sanctions that starved a people still recovering from war Vietnamese aid to Cambodia; medical teams, educators, roads, etc. was slandered as an aggressive occupation, even as the UN upheld the Khmer Rouge collaborators.
With Cambodia still under threat and the Soviet bloc collapsing, Hanoi had to adapt to survive, opening its markets for the first time under the liberalising Đổi Mới reforms in 1986. The reforms mixed market mechanisms with socialist governance, seen as a pragmatic shield against the international sanctions. The core of the revolution endured in its land reforms, public healthcare, and education systems remaining non-negotiable. Western powers spun this as socialism’s “failure,” despite their role in forcing Vietnam’s hand.
By the late 80s Vietnam’s position as Cambodia’s sole ally became an unsustainable drain on its already embattled socialist project. While an already heavily sanctioned Hanoi poured 15–20% of its GDP into rebuilding Cambodia’s infrastructure, the US and ASEAN (led by Thailand) orchestrated a brutal insurgency. Washington funnelled arms to Khmer Rouge remnants through the Eastern Tigers Division on the Thai border, while Bangkok provided sanctuaries and CIA-trained mercenaries, all under the guise of supporting “democratic resistance.” This war-by-proxy bled Vietnam dry, by 1986, 40% of its military was bogged down in Cambodia, rationing food at home while fighting US-Thai-backed guerrillas abroad.
The opposition to the PRK in exile was known as The Coalition Government of Democratic Kampuchea, an alliance of Khmer Rouge, Royalists and Buddhist Nationalists. During the PRK’s decade of reconstruction The Coalition engaged not only in armed insurgency but a mass propaganda campaign largely targeted at Vietnam. This sought to inflame historic ethnic grievances between Khmers and Vietnamese while destabilising efforts at building a socialist society.
It was through this campaign that the conspiracy theory emerged which blamed the Vietnamese for the killing fields of the Khmer Rouge. They claim that the Vietnamese secretly executed intellectuals, officials, and civilians after they took control of the country and staged the bodies at sites like Choeung Ek to look like they were victims of the Khmer Rouge. They argue that the meticulous records kept at Tuol Sleng prison (photos, confessions, ledgers) were forged by Vietnamese intelligence to implicate the Khmer Rouge leadership. The theory suggests the victims shown were actually alive and well until the Vietnamese arrived.
Such fabrications were widely accepted in places like the refugee camps along the Thai border, where refugees were largely cut off from The PRK and still lived under de-facto Khmer Rouge control. The conspiracy even spread throughout The PRK, with many Cambodians unwilling to accept that their fellow countrymen were responsible for such crimes, instead blaming their “historic enemy” of Vietnam. From an interview with a refugee conducted by journalist Henry Kamm in a camp in Thailand “The Vietnamese are clever. They killed the people and left the bodies for the world to see and blame Pol Pot. They want our land, so they must make the world hate us and love them.”
By the mid 80s the guerrilla campaign against the PRK had fractured into increasingly smaller cells which burrowed deep into the PRK’s interior, spreading such counterevolutionary rumors and propaganda, while staging brutal attacks on commune headquarters. The assaults were simple but sophisticated, at times even staged as false flag attacks. While along the entire arc of the border with Thailand insurgents, predominantly Khmer Rouge, still controlled and administered territory. PRK forces organised a mass offensive in 1985, driving out much of the opposition onto the Thai side of the border. They then began a mass fortification project to seal the border, a project known as The Bamboo Wall. A civilian PRK observer described “a long fortification structure composed of a 700km canal, doubled with a wall. In the form of a strategic arc, it will follow 10 km inside the land border from Laos to the maritime border in Koh Kong province. It will be completed in regular intervals by small forts,which are not unlike the Great Wall of China.” During this mass fortification project both sides planted countless thousands of landmines, many of which remain in the soil today– further straining tensions between the Vietnamese support forces and Khmer villagers.
Collapse
The final blow came when Gorbachev’s USSR, Vietnam’s last patron, slashed aid amidst its own crisis. By 1989, with Vietnamese civilians facing food shortages at home and its economy in freefall, Hanoi had no choice but to withdraw, leaving Cambodia to a UN that would resurrect the very same people it had overthrown a decade prior.
The Paris Peace Agreements were signed on October 23, 1991, brokered after years of diplomatic stalemate, the accords mandated a comprehensive political settlement in return for a humongous humanitarian UN aid package. Its most ambitious feature was the creation of the United Nations Transitional Authority in Cambodia (UNTAC), an unprecedented mission granted sovereign power to supervise a ceasefire, disarm combatants, repatriate refugees, and administer the country until free and fair elections could be held as the Kampuchean People’s Revolutionary Party were pressured to abandon Marxism in favour of completely open markets.
It was during the agreements that Hun Sen, a former Khmer Rouge defector turned self described Marxist-Leninist who had been a key figure in the PRK’s administration, flipped once again, taking leadership of the newly formed Cambodia Peoples Party. In 1992 the United Nations sent in UNTAC to govern the country. A $3 billion “peacekeeping” mission that became a vector of colonial plunder and social catastrophe. When the mission arrived it immediately imposed neoliberal shock therapy, modelled on Perestroika, as state enterprises were auctioned to foreign investors.
The mission systematically erased the decade of progress in education, healthcare, agriculture and infrastructure achieved under the PRK, while legitimising the return of exiled elites. Schools and clinics built through collective effort were handed over to private interests, while UN officials encouraged the resurgence of reactionary political factions, such as returning the monarchy to power. The 1993 elections, framed as democratic renewal, served to dismantle revolutionary gains and enforce Cambodia’s submission to global capital.
The mission’s 22,000 personnel, overwhelmingly Western, Thai, and Japanese troops, triggered a public health disaster: UN soldiers frequented Cambodian brothels where HIV/AIDS infection rates soared from an estimated 0.1% in 1991 to 4% by 1995, creating an epidemic that still scars the country to this day.
In 97, Hun Sen led a coup against the fragile elected government, taking power and spending the next two decades consolidating his complete leadership, gradually eliminating all opposition, while maintaining completely open markets and continuing to dismantle any remnants of PRK socialism.
The result was a lost decade where USD flooded into Phnom Penh’s streets, filling them with UNICEF-branded Land Rovers while 40% of Cambodian infants suffered malnutrition. State infrastructure projects were left to crumble under structural adjustment. The steady progress made under the PRK’s system gradually ground to a halt, despite the massive amount of USD thrown at the country. Of course, to release those dollars The PRK’s system had to be abandoned. Today’s sweatshops, asenic-filled streams and incessant land grabs are the logical endpoint of a system where survival is no longer dependent on the economy of solidarity, rather it is commodified by market forces.
The decade-long embattled People’s Republic of Kampuchea was an example of solidarity under the harshest possible conditions. The fraternal project was an essential foundation upon which survival and social reconstruction depended. Despite facing a crippled nation, a decimated population and a relentless, foreign-backed insurgency, this solidarity provided the stability to begin the first stages of healing a broken land in a utopian image. Ultimately, this partnership, though born of profound sacrifice, could not surmount the immense weight of global market inertia, the deeply ingrained nationalist suspicions manipulated by external powers and the unyielding punishment of isolation imposed by the West. The very solidarity that saved a nation was inevitably consumed by the forces it once vanquished.
Cambodian Socialism
Margeret Slocomb wrote in The Revolution After Pol Pot (2004): “Structurally, Cambodia was not ready for revolution, and revolutions cannot be made, or even re-made as in the case of the PRK, when the most fundamental economic and cultural conditions do not exist.” However, this is just the first level of negation. Indeed I would argue that these conditions did exist, albeit under immense pressure caused by the global imbalance of class forces. The PRK’s attempt to build socialism did not fail due to a lack of revolutionary consciousness or internal economic “unreadiness,” rather it succeeded. However, it was subsequently crushed, this was because it was born into a moment and immediately targeted by a world system where market imperialism was nearing its peak strength. The regime’s dependency on the Soviet bloc was a material necessity for survival in the face of a concerted campaign of destruction by the core capitalist powers.
The United States and its allies enacted a total economic and political embargo, a mass propaganda campaign combined with a relentless domestic insurgency. This was a material stranglehold, a deliberate act of economic, political and social warfare designed to sever the PRK’s access to the means of production and reproduction This forced the nascent state into a defensive, dependent posture with the COMECON bloc, which was itself was being crushed under the immense weight of the global market and its own internal contradictions caused by decades of revisionist policies which were amplified by relentless external pressures.
The reality of Cambodian socialism was brutal, but it was made brutal by the forces of reaction sponsored by The West and its allies. For all its flaws, real Cambodian socialism did exist, if not in the halls of ministries of Phnom Penh, it existed in its purest form through the economy of solidarity. What else other than communism or socialism can we call a communal and social construction project alongside the revolutionary will to discard the previous system? Be it a revolution against the Khmer Rogue or prior Royalist regime, to build instead a social order based on the egality and fraternity that had seen them through one of the greatest devastations in world history.
Note: Many of the statistics regarding aid numbers are disputed. We have approxiated and made average from many of the numbers.
