The declassification was authorized by the CIA’s Director of Central Intelligence, and the cable was made available online on the date of its upload to the archive. The Document. The cable opens with a heading indicating its origin and classification status, then proceeds to an assessment of China’s nuclear ambitions. It reads: “Communist Chinese nuclear capabilities. China early aspires to great‑power status, and current Chinese leaders have given a high priority to developing a substantial strategic capability, essential to such goals.

When operational, the MRBM would place all Asian nations, with the exception of parts of India and Indonesia, within range. Yield estimates.

Although that device was not missile‑deliverable, the cable records a test in December nineteen sixty‑seven that was not announced by Peking, describing an unsuccessful attempt to achieve a lightweight thermonuclear device. Future development. The assessment states that Chinese efforts will continue toward the development of intercontinental ballistic missiles (ICBMs) and lesser‑range strategic attack systems. It further notes that by the mid‑1970s China could field a limited number of missile‑based nuclear weapons, with a possible deployment of a thousand‑kiloton warhead on a fixed launch platform. The cable projects that a Chinese ICBM capable of a combat radius of one thousand and fifty nautical miles could become operational by nineteen seventy‑two, assuming no program setbacks.
