Primary Sources
Britannica - "Cambodia: Vietnamese Intervention"
This encyclopedia entry by David P. Chandler, the leading Western historian of Cambodia, provides an authoritative overview of the entire 1979-1991 period. The article documents Vietnam's invasion, the establishment of the PRK government, recovery efforts during the 1980s (restoration of private property, schools, and Buddhist practices), the refugee crisis, resistance coalition formation, Vietnamese withdrawal, and the path to the 1991 Paris Peace Agreements.
Ang Cheng Guan - "Termination of War: The Cambodian Conflict (1978-1991)"
This peer-reviewed academic paper provides comprehensive analysis of how and why the Cambodian conflict ended. Drawing on archival documents from Singapore's Ministry of Foreign Affairs, Ang Cheng Guan examines the war termination process at three levels: the international system, domestic politics, and individual actors (particularly the Sihanouk-Hun Sen meetings). The paper documents ASEAN's diplomatic role, the impact of Soviet reforms under Gorbachev, Vietnam's economic pressures, and the negotiations leading to the Paris Agreement.
U.S. General Accounting Office - "Cambodia: Multilateral Relief Efforts in Thailand" (1991)
This official U.S. government report provides detailed data on refugee camps along the Thai-Cambodian border. The GAO documented that over 360,000 Cambodians lived in border camps as of 1991, with international donors having spent $331 million on border relief operations between 1982 and 1989. The report details camp populations, services provided (including 2,467 calories per day in food rations, medical care, and vocational training), funding sources, and accountability challenges.
The Washington Post - "A Society Whose Sinews Were Ripped Out" (1980)
This long-form investigative article from March 1980 documents the 1979-1980 famine and international humanitarian response. The article provides a detailed timeline of Jacques Beaumont and Francois Bugnion's June 1979 assessment visit, the bureaucratic delays that postponed aid delivery until October 1979, and the contrasting approaches taken by Oxfam versus Red Cross/UNICEF. The reporting reveals both the catastrophic conditions in post-Khmer Rouge Cambodia and the political complications that hindered relief efforts.
Jenny Leigh Smith - "Food Security and Sovereignty in Cambodia, 1979-1989"
This academic working paper provides quantitative analysis of food production, distribution, and international aid throughout the PRK decade. Smith documents that rice harvests never exceeded one million tons during the 1980s despite population needs of 900,000 to 1.5 million tons, challenging narratives about the effectiveness of Western humanitarian aid and documenting continued food insecurity, including a 1988 near-famine. The paper also reveals accountability issues with PRK distribution systems.
The Washington Post - "U.S. to Support Pol Pot Regime For U.N. Seat" (1980)
This September 1980 news report documents Secretary of State Edmund Muskie's announcement that the United States would support seating the Khmer Rouge regime at the United Nations despite its "abhorrent" human rights record. The article explains the Cold War rationale (preventing legitimization of Vietnamese occupation), the influence of China and ASEAN allies, and domestic criticism of the decision, revealing how superpower politics shaped international responses to Cambodia throughout the 1980s.
Yale University Genocide Studies Program - "Chronology of Cambodian Events Since 1950"
Yale's Genocide Studies Program, the world's leading institution for Khmer Rouge research, provides an authoritative timeline of key events from 1950 through 1999. For the PRK period, the chronology documents precise dates for the Vietnamese invasion, government formation, resistance coalition creation, Hun Sen's rise to prime minister, Vietnamese troop withdrawal, and the October 23, 1991 Paris Peace Agreements.

This educational resource provides an extremely detailed timeline of the "Conflict Phase (December 3, 1978 - October 23, 1991)" with specific events, casualty figures (200,000 killed including 25,000 Vietnamese soldiers, 365,000 refugees, 2 million internally displaced), international actors, and UN involvement.

Los Angeles Times - "Killing in Cambodia: A Tale of Two Decades" (1989)
This opinion piece by Joel R. Charny, Asia regional director for Oxfam America, provides a first-person perspective from a humanitarian worker with nine years of experience in Cambodia (1980-1989). Charny describes Phnom Penh's recovery to 800,000 residents by 1989, the effects of the international embargo on economic development, human rights concerns, and the Hun Sen-Sihanouk dialogues as signs of hope for settlement.
The Diplomat - "Remembering Cambodia's Pen Sovann" (2016)
This profile of Cambodia's first PRK Prime Minister reveals the extent of Vietnamese control over the government. Pen Sovann's removal and eleven-year imprisonment in Hanoi after refusing Le Duc Tho's demands (for over 200,000 Vietnamese troops, population relocations, and Vietnamese use of Cambodian land) documents the tensions between Cambodian autonomy and Vietnamese oversight during the 1980s.
