Chinese People's Volunteer Army in Korea (1950-1953)
China deployed 2.97 million troops to support North Korea against United Nations forces, officially as "volunteers" to avoid formal war with the United States. Chinese forces suffered an estimated 180,000 to 400,000 deaths, with total casualties potentially exceeding 900,000. The intervention prevented North Korea's collapse and preserved the Kim regime.
Chinese forces pushed UN troops back from the Yalu River to roughly the 38th parallel, where the front stabilized.
The intervention cemented the Sino-North Korean alliance and established the precedent of major powers deploying "volunteers" to avoid direct great-power conflict.
North Korea is now in the position China occupied 75 years ago—deploying troops labeled as something other than official military forces to support an ally in a war against Western-backed opponents. The parallel is not lost on Pyongyang, which frequently invokes Korean War sacrifice in domestic propaganda about the Ukraine deployment.
