Sino-American Cooperative Organization

World War II intelligence organisation

The Sino American Special Technical Cooperative Organization, also known as the Sino American Cooperative Organization (SACO), was an organization created by the SACO Treaty signed by China and the United States in 1942 during the Second World War. It established a mutual intelligence gathering entity in China between the respective nations against Japan. It operated in China jointly along with the Office of Strategic Services (OSS), America's first intelligence agency and forerunner of the CIA while also serving as joint training program between the two nations.

The first and last operational chief of the organization was Dai Li (Tai Li, Dai/Tai is the surname), head of Chiang Kai shek's secret police, the Bureau of Investigation and Statistics. A fierce anti communist and shadowy man of mystery, General Dai also commanded the Loyal Patriotic Army (LPA), a large militia force active in Japanese occupied interior regions of China. Commander for the American forces was United States Navy Captain Milton E. Miles. "Mary" Miles, later a Vice Admiral, was commander of Naval Group China (NGC), the American Navy's intelligence unit in China during the war. In April 1943, SACO began setting up camps (later known as units when Naval Group China was established) to train Chinese guerrillas in small arms, demolition, sabotage, combat techniques, radio handling, aircraft and ship recognition, and aerology. Many, if not most, of the American instructors had backgrounds in law enforcement prior to the war. While some of the recruits the Chinese provided were unhealthy to some degree, they surprised their instructors with their willingness and ability to learn. The official SACO organization dissolved in 1946 after the close of the war, with the subsequent departure of the Naval Group China. However some KMT loyal SACO trained guerillas continued aggression against the CCP during the civil war (1946–1949). SACO arrested, tortured, and killed political dissidents. For a long period after the Communist victory in the Chinese Civil War, SACO became associated with imperial foreign aggression and atrocities of the revolution were attributed to sinister US involvement. The Chinese government memorialized incidents of torture and massacre at Chongqing former SACO lt=headquarters at Happy Valley, and displayed the "Gele Mountain Revolution Memorial Museum" in Geleshan, citing American supplied handcuffs and weapons in the exhibition as evidence of American involvement. The coalition was blamed for atrocities committed years after dissolution, with no acknowledgement of SACO's participation in the war against Japan. Only recently has the government taken a position to "restore history's original face." The 1953 movie Destination Gobi is a highly fictionalized account of one group of weather observers. SACO is specifically mentioned as their parent organization.
