This is a collection of documents about the repatriation and return migration of individuals of Korean ethnicity back to North Korea after the Korean War. Several waves of ethnic Koreans returned to North Korea during the Cold War, coming from Northeast China, or Manchuria, and Japan. The collection is composed predominantly of Chinese Foreign Ministry documents about repatriations from Northeast China. A smaller number of sources from Hungary and other countries concern the repatriation of Koreans from Japan.
