What did the declassified documents reveal?

Mao’s Red Guard Diplomacy: 1967 is a declassified Central Intelligence Agency intelligence report dated June twenty‑first, nineteen sixty‑eight. The document is notable because it offers a contemporaneous analysis of the extraordinary and, by the agency’s own assessment, irrational diplomatic conduct of Communist China during the height of the Cultural Revolution. The report was approved for release in May two thousand seven. It was made publicly available through The Black Vault, which hosts the full text as part of its online archive of declassified U.S. government records. The declassification authority is the Director of Central Intelligence, and the release was issued under the agency’s standard classification review procedures. The document begins: “APPROVED FOR RELEASE DATE: MAY 2007 DIRECTORATE OF INTELLIGENCE Intelligence Report MAO’S RED GUARD DIPLOMACY: 1967 (Reference Title: POLO XXXI) SEGRET RSS No. 0029/68 June twenty‑first, nineteen sixty‑eight MAO’S RED GUARD DIPLOMACY: 1967 For several months during 1967 Communist China’s diplomacy was characterized by an extraordinary degree of irrationality. In Peking, foreign embassies were violated and their personnel abused. Abroad, Chinese diplomatic personnel staged provocative demonstrations and went out of their way to insult host governments. The purpose was to bring the benefits and therapeutics of Communist China’s “cultural revolution” to foreign policy and the foreign policy establishment. It was as though the Chinese, in their dealings with foreigners, were seized by a kind of madness; for a time Peking’s usual non‑diplomacy—or at best semi‑diplomacy—gave way to outright anti‑diplomacy. The injection of this aspect of the “spirit of Mao” into the foreign ministry and onto the foreign scene was resisted by Foreign Minister Chen Yi, a man of remarkable courage, outspokenness, and style. No other ranking official has stood so openly and stubbornly against Mao’s “cultural revolution” and survived. Only the support of his long‑time, close colleague Zhou En‑lai seems to have saved him for the time being. Although partially bent to Mao’s will, Chen, with Zhou’s backing, won his struggle, at least for the present, to eliminate the irrationalities of the “cultural revolution” from the mainstream of foreign policy. This Intelligence Report, produced solely by the Special Research Staff, reviews and analyzes these and other extraordinary aspects of Communist China’s conduct of foreign affairs during 1967.
