The economic factor in the Sino-Vietnamese split, 1972–75: An analysis of Vietnamese archival sources

Abstract

Relying on so far untapped Vietnamese archival sources, this article examines the impact of China's gradual curtailment of its economic assistance to the Democratic Republic of Vietnam's (DRV) war and economic recovery efforts and its implications for Sino-Vietnamese relations between 1972 and 1975. While Beijing's gradual reduction of aid to the DRV during this period was primarily motivated by the declining importance of North Vietnam to China's strategic security combined with the reality of China's domestic economic hardship which largely resulted from the disastrous Cultural Revolution of 1966–69, Hanoi's reactions and policy responses were driven by their deep-rooted perception of Beijing's insincerity and hidden intention to keep Vietnam weak. The Sino-Vietnamese conflict that ensued after 1975 was not inevitable; Hanoi's leaders launched concerted diplomatic efforts to improve economic relations with Beijing throughout 1975 because they clearly recognised the importance of China's continued economic assistance and preferential trade agreements to its first five year plan (1976–80). However, Beijing's unchanged position and hasty decision to totally cut off aid to Vietnam and additionally take punitive economic measures against Vietnam's first five-year plan in late 1975 while at the same time increasing economic and military aid to the Democratic Kampuchea compelled Hanoi to tilt closer towards Moscow.
