What did the declassified documents reveal?

Recent declassified Army intelligence, titled “Intelligence Note on alleged coup activity in Communist China, January twenty‑third, nineteen sixty‑seven,” provides a snapshot of U.S. assessments during the early months of the Cultural Revolution. The note is notable for its contemporaneous references to accusations circulating in Chinese media and for the way it links those accusations to broader concerns about Soviet involvement and possible unrest within the People’s Liberation Army. The document was released through a Freedom of Information Act request filed by the public, identified in the Black Vault’s archive under the entry for U.S. intelligence on China.

This was the second major charge of coup plotting that we have seen in the mass of material coming out of China on the ‘cultural revolution.’ Earlier, in January, there were reports of posters accusing Lo Jui‑ching and Ho Lung, a Politburo member and prominent military figure, of having attempted a coup in February 1966. Aside from ‘cultural revolution’ accusations, clandestine information has suggested independently that an anti‑regime incident may have occurred in early 1966. A March report quoted a Japanese Communist Party source saying that a pro‑Soviet coup had taken place in China during the previous month and that Mao had been put under house arrest. A report received last week tells of a speech given on August second by Teng Hsiao‑p’ing to a group of Peking students in which Teng replied to a question about a ‘February mutiny.’ After first declaring that there had been ‘no such thing,’ Teng asserted that the inquiry was probably based on the…
