Prison Camps” published by the U.S. Committee for Human Rights in North Korea and distributed it, and produced an educational documentary titled “Are you listening to our story?” which illustrates cases of human rights violation in North Korea. ② Investigation of Human Rights Conditions of Children of North Korean Defectors Living Overseas The NHRCK conducted an investigation of the human rights conditions of children left behind, whose mothers married local males or were trafficked during their stay overseas such as China and were later repatriated to North Korea or entered Korea. The investigation validated that the number of those defecting mothers’ children born in China is estimated to be as high as 20,000 to 30,000 and that the number of children requiring actual care due to family disruption resulting from the repatriation of their mothers or her entering South Korea is about 4,000. Given that the root cause of such children issues lies in family disruption stemming from the Chinese government’s forced repatriation, several policy agendas have been proposed, such as the necessity of diplomatic efforts to resolve this, and the need for measures that can bring those children requiring protection into South Korea. 3) Strengthening International Cooperation ① International Symposiums The NHRCK hosted an international symposium under the theme of “Analysis and Projections on the Situation of Human Rights in North Korea, Policy Suggestions for Advancing North Korean Human Rights (Role of International Society)” in order to introduce its activities and roles in promoting North Korean human rights to the international society and strengthen cooperation with the international society on policy directions and strategies for improving the human rights of North Koreans.
