What did the declassified documents reveal?

Chinese strategic weapons program, National Intelligence Estimate, February twenty‑seventh, nineteen‑sixty‑nine, Central Intelligence Agency. This declassified assessment offers a snapshot of U.S. intelligence on the People's Republic of China’s nuclear and missile development during the height of the Cold War, and it has been cited in numerous studies of East Asian security. The document was released under a Freedom of Information Act request in June two‑thousand‑four, with approval for public release noted on the first page. The declassification authority was the CIA’s Office of Information Management, and the full text is available through the Black Vault archive. General considerations. Chinese efforts to develop modern weapons began in the late nineteen‑fifties, when the original program took shape with Soviet technological and material assistance. At that time Chinese expectations for rapid progress in the nuclear field and in a range of tactical and strategic missiles appeared high, but the sudden withdrawal of Soviet technicians in nineteen‑sixty and the economic contraction and depression of the early nineteen‑sixties resulting from the Great Leap Forward had a severe impact on the advanced weapons program. Nevertheless, despite economic and political crises, Peking persisted in giving high priority to development of advanced weapons and gradually progress was made. A more rational program concentrating research and development in nuclear weapons, surface‑to‑air, and medium‑range ballistic missiles emerged during nineteen‑sixty‑three to nineteen‑sixty‑five. In nineteen‑sixty‑five, reporting began to suggest increasing Chinese interest in an intercontinental ballistic missile. By the end of nineteen‑sixty‑six the Chinese had demonstrated their understanding of the basic principles of thermonuclear design. In nineteen‑sixty‑seven the medium‑range ballistic missile program was judged likely to have reached the stage where deployment could soon begin and the ICBM program was considered likely to have reached the stage where missile testing could start. Subsequent events, however, showed that the Chinese program had probably not advanced as far as we had believed, and, in general, the programs have not moved forward as fast as we once thought likely. We have received no information of activity related to the construction of operational sites for medium‑range missiles, and there have been no indications that ICBM flight testing has occurred. The record of the last two years thus raises some perplexing and complicated questions about the pace and direction of the Chinese effort and what factors control it. A principal problem is that there is no adequate historical background for judging China’s technical and industrial capabilities for producing and deploying weapons systems combining advanced technologies. It could be argued, for example, that most of the progress in modern weapons recorded thus far has been in research and development, and…
