What did the declassified documents reveal?

This is Declassified. Today, we're examining a declassified C.I.A. intelligence brief titled "China- Treaty with U.S.S.R. Secret, Intelligence Brief," dated approximately February twenty-fourth, nineteen-fifty. This document provides an early assessment of potential secret protocols accompanying the recently announced treaty between China and the Soviet Union. You can find this document on archive.org, originally sourced from documents2.theblackvault.com. This document was released to the public under the Freedom of Information Act. The precise F.O.I.A. case number is not listed in the public archive, but the document was declassified by an interagency declassification review. The original classification was "Secret." The document states: "Regarding FAR EAST CHINA TREATY WITH U.S.S.R. Secret Protocols. The recently announced treaty between China and the U.S.S.R. was almost certainly accompanied by secret protocols designed to provide for a stronger Soviet position in the Chinese military organization, in strategic segments of the Chinese economy, and in China's border regions.

Economic Terms. In the economic field, the U.S.S.R. has probably obtained secret rights to maintain its preferred position in Manchuria, establish Soviet trading firms, assign Soviet advisers and technicians to strategic segments of the Chinese economy, extend Soviet air privileges in the border regions and to China proper, and engage in preclusive buying of strategic minerals. One economic pact may deal specifically with Sinkiang; an arrangement for the joint development of that province, together with provision for Soviet advisers with the provincial government, would make it unnecessary for the U.S.S.R. to seek territorial concessions in Sinkiang at this time. Possible Friction. Meanwhile, friction will probably develop between China and the U.S.S.R. over implementation of the published four hundred million dollar credit agreement. As in the case of similar Soviet credits to the European Satellites, the U.S.S.R. may use the agreement as a lever to extract concessions from the Chinese. The U.S.S.R. will not only tend to overrate the…
