North Korean defectors are North Koreans who have fled from the country in spite of legal punishment for political, ideological, religious, economic, moral, personal, or nutritional reasons after the division of Korea after the end of World War II and the Korean War. North Koreans flee to various countries, mostly South Korea and China. In South Korea, they are referred to by several terms, including "northern refugees" and "new settlers".
Towards the end of the North Korean famine of the 1990s, there was a steep increase in defections, reaching a peak in 1998 and 1999. Since then, some of the main reasons for the falling number of defectors have been strict border patrols and inspections, forced deportations, the costs of defection, and the end of the mass famine that swept the country when Soviet aid ceased with the dissolution of the USSR. The most common strategy of North Korean defectors is to cross the Chinese border into Jilin and Liaoning provinces in northeast China. About 76% to 84% of defectors interviewed in China or South Korea came from the Northeastern provinces bordering China.
The defectors usually flee to a third country due to China being a relatively close ally of North Korea. China, being the most influential of the few economic partners of North Korea while the country has been under U.N. sanctions for decades, is also the largest, and has been a continuous aid source of the country. To avoid worsening the already tense relations with the Korean Peninsula, China refuses to grant North Korean defectors refugee status and considers them illegal economic migrants. If the defectors are caught in China, they are repatriated back to North Korea, where rights groups say they often face harsh interrogations and years of punishment, or even death, in kwalliso prison camps (such as the Pukch'ang camp), or in kyohwaso reeducation camps (such as the Chungsan camp or Chongo-ri camp).
Different terms, official and unofficial, refer to North Korean refugees. One such term in South Korea is "northern refugees" ( or ).
