South Korean defectors

After the Korean War, 333 South Korean people detained in North Korea as prisoners of war chose to stay in North Korea. During subsequent decades of the Cold War, some people of South Korean origin defected to North Korea as well. They include Roy Chung, a former U.S. Army soldier who defected to North Korea through East Germany in 1979. Aside from defection, North Korea has been accused of abduction in the disappearances of some South Koreans.

Occasionally, North Koreans who have defected to South Korea decide to return. Since South Korea does not permit its naturalized citizens to travel to the North, they have made their way back to their home country illegally, and thus became "double defectors". From a total of 25,000 North Korean defectors living in South Korea, about 800 are missing, some of whom may have returned to the North. The South Korean Ministry of Unification recognizes only 13 defections officially, as of 2014^[update].
