What did the declassified documents reveal?

The record you are hearing is a Central Intelligence Agency, Office of Political Research, Progress Report No. 18, dated twelve October nineteen seventy‑six, titled “The Likelihood of Sino‑Soviet Hostilities.” It appears in the public archive of declassified intelligence on China and was released through the Black Vault website. The document was declassified and approved for public release on five January two thousand five under a standard declassification authority.

The report opens with a brief description of the project: “This project consists of two quantitative approaches to Sino‑Soviet relations.

In addition to the regular scenarios of hostilities reported in this project, various scenarios of improved Sino‑Soviet relations are being assessed on an experimental basis. Initial results, based on the events of the past month, indicate a slight Soviet willingness to improve relations and a clear Chinese aversion to any type of improvement, especially in party‑to‑party relations. Future issues of this publication will attempt to follow the probability of improved relations also.” The report then lists items of evidence considered in the revision of six October: “1. The message of condolence sent by the CPSU to the Chinese on the occasion of Mao’s death was rejected. A spokesman for the Chinese Foreign Ministry was quoted as saying that the message was unacceptable because the Soviet and Chinese Parties do not have formal relations. Messages from Poland, Hungary, Bulgaria, Czechoslovakia, and East Germany were also rejected. A government message sent by Hungary was accepted. Later, the messages sent by the French and Italian Communist Parties were also…
