What did the declassified documents reveal?

This is a declassified Central Intelligence Agency record concerning a probable Chinese collection of United States satellite imagery, dated August 1973. The document is notable because it details a series of requests made to a U.S. earth‑resources data center that appear to have been placed on behalf of the People’s Republic of China, and it assesses the potential military value of the imagery. The record was released under a Freedom of Information Act request, case number unknown, with an approval for release dated March 2001.

During that period, the Chinese have used numerous international channels to acquire a considerable variety of products useful to missile‑targeting programs. Order lists have included topographic, gravity, aeromagnetic, and hydrographic maps and charts. Large‑scale topographic maps have been requested most frequently, with offers up to five thousand dollars per sheet for coverage of the Soviet Union near the Chinese border. Several Chinese orders during 1971 and 1972 also requested United States publications on remote sensing of the environment. The suspected Chinese ERTS order is detailed in at least six letters to the Data Center between September 1972 and July 1973. The first inquiry requested general information on the types of ERTS products available and on ordering procedures. A follow‑up letter in October 1972 indicated that, because the quantity of data was very large, the client wished to obtain a sample of each available product before deciding on the final order.
