From Socialism to Expansionism by Martin Jordan, examines Vietnam’s transformation from a revolutionary force to a regional hegemon following its 1975 victory. It details how Vietnam’s economic crisis—marked by a food deficit of 4.4 million tons, the collapse of its Five-Year Plan, and failed collectivization—drove its military occupation of Kampuchea. The text exposes how Hanoi’s vision of an Indochinese federation, with Kampuchea as an agricultural hinterland, led to war, economic decline, and growing dependence on the Soviet Union.
