The human right to health of over 1,080,000 citizens living near Punggye-ri nuclear test site in North Korea is potentially at risk. In early 2024, the South Korean Ministry of Unification identified 17 among 80 North Korean defectors who suffered from chromosomal abnormalities, raising the possibility of severe impact from radiation exposure. The United Nations (UN) has played a pivotal role in promoting climate and human rights norms, intended to induce policymaking that is more supportive of both climate change and human rights. Furthermore, the UN and related agencies have perhaps been the only forces to provide humanitarian aid for the disaster-affected citizens in North Korea. The Kim Jong-un regime has been incapable of meeting the needs of its citizens and has systematically violated their human rights by prioritizing its nuclear program. This article analyzes the current human rights shortcomings of the Kim Jong-un regime, particularly the human right to health of its citizens, which it has put at risk in the region near the Punggye-ri nuclear test site. Further, this article analyzes past efforts at socialization in the context of intergovernmental organizations (IGOs) and how IGOs have contributed to promoting North Korean policymaking more supportive of climate and human rights norms by the Kim Jong-un regime. It argues that the application of socialization in the IGO context should also be undertaken to address the human rights situation of North Korean citizens living near the Punggye-ri nuclear test site to encourage greater adherence to climate and human rights norms by the Kim Jong-un regime.
