What did the declassified documents reveal?

This is a declassified Central Intelligence Agency intelligence report on Peking’s support of insurgencies in Southeast Asia, originally produced in April nineteen seventy‑three. The document is notable because it offers a contemporaneous assessment of Chinese covert activity in Burma, Thailand, Malaysia and the Philippines during a period of shifting Cold‑War dynamics. The report was approved for release in May two thousand seven under Executive Order one two nine five eight, sections three point three(b) and six point two(c). It was made public through a Freedom of Information Act request, case number not disclosed, and posted on the Black Vault website. The declassification authority cited the same Executive Order provisions. The full text is available at the Black Vault archive and the canonical URL on the Internet Archive. Executive Summary This study establishes the facts and examines the purposes of China’s support of insurgencies in Southeast Asia. It is a fact that, despite China’s overall policy of friendly relations, and despite the passage of some four years since the general ending of Cultural Revolution militancy, China continues to sponsor and support insurgencies against certain governments in Southeast Asia. In the cases of Burma and Thailand, such covert assistance has significantly expanded: high‑ranking officers from the People’s Liberation Army’s eleventh Army perform command roles in insurgent headquarters; PLA officers and non‑commissioned officers help train the ranks of insurgent combat forces; PLA units in nearby Yunnan Province train and supply the rebels; and China‑based “insurgent” radio stations beam operational guidance and anti‑government propaganda into Burma and Thailand. These remote insurgencies are not likely to threaten the Rangoon or Bangkok governments, but the fact remains that China’s covert sponsorship of these insurrections is clearly impeding China’s diplomatic attempts to elicit further responsiveness from these same governments. The study examines various possible purposes behind this self‑defeating course—what the Burmese call “two‑faced.” Is the Chinese purpose essentially that of attempting to exert added pressure on certain of China’s small neighbors? Or a concern not to be up‑staged by any new Soviet presence in Southeast Asia and in the support of revolutionary movements? Or an unwillingness or inability to cease supporting insurgencies once begun? Or bureaucratic disarray in the conduct of Chinese foreign relations? Or, a reflection of Maoist impulses? The study concludes that it is the latter of these purposes which carries the greatest force: China supports certain insurgencies in Southeast Asia largely because that is the way the boss, Mao Tse‑tung, wants it—for his own mix of stubbornly held ideological and personal reasons. The report notes that Peking maintains a two‑level foreign policy with respect to certain governments in Southeast Asia: ostensibly friendly diplomacy on one level…
