Chinese Military Modernization: The Western Arms Connection

Published online by Cambridge University Press:  17 February 2009

Extract

During the period 1952–57 the United States attempted to convince other western states to maintain a “China differential” in their trade with communist states. Washington argued that special export controls should be imposed against the People's Republic of China because Beijing represented a unique threat to the west as a whole and because economic warfare would contribute to the ultimate collapse of Mao Zedong's regime. It became increasingly more difficult for the U.S. to sponsor such a policy in multilateral western forums such as COCOM (the Consultative Group-Co-ordinating Committee) during this five-year period. The opposition to the China differential was organized by Great Britain, which argued that the existing system of joint export controls could not be maintained if members attempted to distinguish between communist states on political grounds. Great Britain also questioned the underlying premise of Washington's argument: that east-west trade could be manipulated for political and strategic purposes. The China differential was formally rejected by most of America's allies in 1957, and Chinese trade with West Germany, France, Italy and the United Kingdom increased by 338 per cent, 95 per cent, 214 per cent, and 153 per cent respectively from 1956 to 1958.
