Between Aid and Restriction: Changing Soviet Policies toward China’s Nuclear Weapons Program: 1954-1960
NPIHP Working Paper #2. Based on newly-available archival material from Chinese sources, the paper explores the relationship between Soviet Union and China during the 1950s and 1960s as the latter sought to establish their atomic industry and develop a nuclear weapon with Soviet scientific and technological assistance.
The paper's key findings include:
- Soviet aid to China’s nuclear program has typically been viewed by historians as a product of both Soviet leader Nikita Khrushchev’s romantic belief in world socialist revolution, and the strength of the Sino-Soviet alliance.
- New Chinese archival sources presented by Shen and Xia in Between Aid and Restriction, suggest that the history of Chinese-Soviet nuclear cooperation may need to be re-examined: Khrushchev only consented to assist China in developing nuclear energy for peaceful purposes in 1954 because of the post-Stalin power struggle within the Soviet government—during which he expected to acquire much-needed political support from Mao.
- Consequently, Soviet support for the Chinese nuclear energy program between 1954 and 1957 included the construction of a research reactor and cyclotron in China, cooperative uranium prospecting and mining, the establishment of an Eastern Atomic Energy Institute to train specialists in nuclear technology, and other training for Chinese scientists and technicians.
- Despite the peaceful nature of Soviet aid, Mao intended from the outset to use Soviet support to lay the foundation for a nuclear weapons program.
- Soviet support for China’s nuclear program expanded to include directly weapons-related assistance in 1957, after Mao once again expressed his support to Khrushchev following the so-called anti-party incident which threatened to cost Khrushchev his leadership position in the Soviet Union.
- Soviet support for Chinese nuclear weapons development included assistance in uranium enrichment, plutonium reprocessing, warhead design and production, as well as missile technology development.
- Summer 1958 marked the beginning of the end of Soviet nuclear assistance to China, when the PRC bombardment of Jinmen Island, off Taiwan, caught Moscow off guard.
- China’s failure to turn over a captured US-made Sidewinder missile to the Soviet Union for study contributed to the deterioration of Sino-Soviet nuclear relations.
- By 1959, with Khrushchev’s position as leader of the USSR now secure, the flow of Soviet nuclear aid to China became increasingly limited in pace, scope and depth.
- The Soviet decision not to send a long-promised Atomic bomb teaching model to China was among the most concrete manifestations of the deteriorating Sino-Soviet relationship.
- By August 1960 the last of the Soviet nuclear advisors in China had returned to the USSR.
- Soviet assistance had helped China establish a comprehensive nuclear science and technology industry. The end of Soviet aid was a significant set-back, but it came far too late to halt China’s nuclear development completely. China’s first atomic bomb test took place on 16 October 1964.
