What did the declassified documents reveal?

This declassified Central Intelligence Agency memorandum, dated December twenty-sixth, nineteen-fifty-one, records an assessment by the Intelligence Advisory Committee's Watch Committee regarding a possible Chinese invasion of Indochina. This document is archived at theblackvault.com. This document was released under the Freedom of Information Act as part of a collection of U.S. intelligence records on China. The declassification authority is not specified on the document itself. The document, an Office Memorandum from DRS, Mr. Mose Harvey, to R, Mr. Howe, is titled "Conclusions about China's Imminent Invasion of Indochina." One. The Watch Committee of the I-A-C at a special meeting this morning reviewed intelligence indications of a possible Chinese invasion of Indo-China. The review was undertaken immediately because of the statement of French Premier Pleven that "the possibility of Chinese intervention in Indo-China appears to be becoming more definite" (Paris, Telegram No. 3765, December twenty-second). Two. The Watch Committee has had the Indo-Chinese situation under close study for the past several weeks and has evaluated a flurry of reports suggesting the possibility of an early Chinese invasion. The developments cited by the French Premier are confirmed by U.S. intelligence sources, with the exception of (a) an alleged recent increase in Chinese Communist propaganda attention to the Indo-Chinese struggle, which appears exaggerated, and (b) the estimated size of the troop build-up in the southern provinces bordering Tonkin. These developments, however, are not new and do not, in the opinion of the Watch Committee, indicate a sudden increase in the urgency of the situation. Three. The Watch Committee concluded that while Chinese Communist intervention in Indo-China remains a definite possibility, no information at hand indicates that it is now imminent. Chinese Communist aid to the Viet Minh is definitely increasing, as are Chinese Communist preparations for a possible intervention at some future time. But in neither instance is there any development which indicates that the situation has reached a point where a new turn of events appears likely. Rather continuation of the present type of Chinese Communist aid is suggested, with large scale intervention appearing unlikely before at least two or three months. Moreover, the over-all Chinese situation continues such as to appear to make improbable a Chinese movement in force until the Korean conflict is ended. The remainder of the document consists of administrative and security markings. This is what the public record looks like at its most ordinary. storyflo.com. The canonical U-R-L for this document is archive.org/download/us-china-intel-CI00855/CI00855djvu.txt.
