What did the declassified documents reveal?

This is a declassified United States intelligence brief on Chinese Communist military forces, dated March sixth, nineteen fifty-one. It is notable as a weekly estimate that outlines the perceived threat to Formosa and the broader strategic calculations of the United States and the Soviet Union in the early Cold War period. The source is the public archive at The Black Vault. The document was released to the public through The Black Vault’s digital collection. It appears in the archive under the identifier CI00671 and was made available online as a scanned text file. The declassification authority is listed as the United States government, with the release occurring as part of the agency’s routine declassification and public‑access program.

Comments: The shifting of Communist forces toward the east coast has been previously noted. G‑2 estimates the strength of the Communist forces in the region opposite Formosa at forty thousand in the Swatow sector of eastern Kwangtung and approximately one hundred thousand six hundred in Fukien Province. This total includes two divisions each from three armies which have moved into the coastal area in recent weeks. Contrary to the current report, the Nationalists have reported a number of times in recent weeks that shipping is concentrated along the coastal areas, particularly the Pukien east. Reviewing the overall situation in Southeast Asia, Chinese Communist military aid to the Viet Minh continues, although the border area is generally quiet for the moment. Chinese Communist propaganda against Thailand has been intensified, and anti‑colonial demonstrations have taken place in the Philippines directed against the plan to use the island as a Western military base.
