The New York Times (Feb 18, 1979), quoted Taiwanese officials saying that American decision to normalise relations with China had encouraged Beijing to undertake this invasion to irritate the Soviet Union. A story quoted much later by Japanese sources said that Deng Xiaoping, during his “charm offensive” to the West, had reportedly told US President Jimmy Carter in January 1979 that “The little child is getting naughty, it’s time he gets spanked.”
Initially, Mao’s China and Communist North Vietnam had cordial relations. Like in North Korea, China dispatched 3,20,000 PLA troops to help North Vietnamese legend Ho Chi Minh to fight the French colonialists and later the Americans. In 1974, China captured Paracel Islands in South China Sea from the anti-Communist regime in Saigon, South Vietnam. In 1975, both Vietnams were joined under the Communist rule.
