The document was released to the public through The Black Vault’s digital collection, posted on the archive.org site under the title “US Intelligence on China CI01166.” The release date is listed as the date of upload, and the declassification authority is the Central Intelligence Agency, which authorized the disclosure of this top‑secret cable as part of its historical records program.
