The Third Indochina War This book looks afresh at some of the key issues of the Third Indochina War, fought between Vietnam, China and Cambodia. Although the wars that erupted at the end of the 1970s redefined international relations in Eastern Asia to a larger degree than any other set of events, few scholars have attempted to revisit their causes and effects since Russian and Chinese arch- ives were opened up in the early 1990s. Drawing on these new sources, this volume reinterprets the causes of the Vietnamese–Cambodian and Sino-Vietnamese conflicts, looking at the long- term and immediate origins of the wars. It shows both the links between policies and policy assumptions in the different countries that were involved and the dynamics – national, regional and international – that drove these conflicts towards war. Rather than explaining the conflicts in terms of age-old resentments and suspicions, or seeing war between the former allies as the necessary outcome of the conflicts of the 1970s, the contributors have set out to look at the concrete causes for the breakdown in cooperation and the road to war. This book will be of much interest to all students of the Cold War, Southeast Asian history, international relations and security studies in general. Odd Arne Westad is convenor of the Department of International History at the London School of Economics and director of its Cold War Studies Centre. Sophie Quinn-Judge is Associate Director of Temple University’s Center for Vietnamese Philosophy, Culture and Society and a Senior Lecturer in History at Temple. Cass Series: Cold War History Series Editors: Odd Arne Westad and Michael Cox ISSN: 1471–3829 In the new history of the Cold War that has been forming since 1989, many of the established truths about the international conflict that shaped the latter half of the twentieth century have come up for revision. The present series is an attempt to make available interpretations and materials that will help further the development of this new history, and it will concentrate in particular on publishing expositions of key historical issues and critical surveys of newly available sources. 1 Reviewing the Cold War Approaches, Interpretations, and Theory Odd Arne Westad (ed.) 2 Rethinking Theory and History in the Cold War Richard Saull 3 British and American Anticommunism before the Cold War Marrku Ruotsila 4 Europe, Cold War and Co-existence, 1953–1965 Wilfred Loth (ed.) 5 The Last Decade of the Cold War From Conflict Escalation to Conflict Transformation Olav Njølstad (ed.) 6 Reinterpreting the End of the Cold War Issues, Interpretations, Periodizations Silvo Pons and Federico Romero (eds) 7 Across the Blocs Cold War Cultural and Social History Rana Mitter and Patrick Major (eds) 8 US Paramilitary Assistance to South Vietnam Insurgency, Subversion and Public Order William Rosenau 9 The European Community and the Crises of the 1960s Negotiating the Gaullist Challenge N.

Introduction From war to peace to war in Indochina Odd Arne Westad The wars between Vietnam, Cambodia, and China in 1978–1979 created shock-waves within the international system of states. Not only was this the first time that countries led by Communist parties had been at war with each other, but these wars also happened in the immediate aftermath of the Second Indochina War, during which the Vietnamese, Chinese, and Cambodian Communists had been allies fighting the United States. For many, the world seemed to have turned upside down. The certainties of the past – especially the question of who was allied to whom – seemed to evaporate alongside the hopes for stability and peace in Indochina. Those in the West who had sup- ported the US intervention against Vietnamese Communism as a necessary containment of China were in for a particularly rude shock. “These wars exploded our world-view,” one of them said; “... they gave accepted truths a real beating.”1 But, if the West was shocked, the shock in the Third World was perhaps even greater. I was in Mozambique in December 1978, and remember how many young activists in Maputo came to discuss the Vietnamese war against Pol Pot. There was disbelief in their eyes when they read the news. To the new post-colonial Mozambican elite, eager to ally itself with the socialist states and build socialism in their own country, the fact that two declared socialist states were now at war with each other was very hard to swallow. Even if much was already known about the atrocities the Khmer Rouge had per- petrated against the people of Cambodia, Cold War labels tended to obscure this knowledge. Socialist countries simply did not fight each other, I was told again and again. The war had to be an imperialist provocation, especially since the peoples involved were the “heroic” peoples of Indochina, who had provided so much inspiration for left-wing movements across the Third World in the 1960s and 1970s. “After this,” I remember one young activist telling me, “the world will never be the same again.” But if December 1978 was bad enough for Third World socialism, matters got worse the following year. The Chinese invasion of Vietnam added to the sense of confusion, although most left-wing movements concluded rather quickly that China had become an opponent rather than a supporter of social- ism in the Third World. The worst shock, however, was the documentation of
