Kim Yong Chol, the vice-chairman of the North Korean Workers' Party's Central Committee, will lead a high-level delegation to the closing ceremony of the Winter Olympics in Pyeongchang on Sunday. The delegation is also scheduled to meet with President Moon Jae-in. Kim Yong Chol previously served as the chief of the Reconnaissance General Bureau, a prominent North Korean military intelligence agency that South Korea accused of being responsible for the 2010 sinking of the Cheonan, a South Korean navy corvette. North Korea has denied any involvement in the incident. In light of the current challenging circumstances, the South Korean Unification Ministry has stated that the focus will be on the potential for peace on the Korean peninsula and improved inter-Korean relations through dialogue with the visiting North Korean officials, rather than dwelling on their past actions or identities. Kim's visit will coincide with Ivanka Trump's visit to South Korea for the Winter Olympics' closing ceremony. The Blue House stated that there are no official plans for U.S. and North Korean officials to meet. South Korea's decision to allow Kim, who is under sanctions by the U.S. and South Korea, to cross the border has caused protests from family members of deceased Cheonan sailors and opposition parties. The main opposition Liberty Korea Party staged a protest in front of the Blue House, criticizing President Moon's decision to accept North Korea's peace offering. A group of relatives of the victims of the Cheonan sinking announced plans to hold a press conference to protest the decision. Despite public concerns about Kim's upcoming visit, the South maintains that the sinking was caused by North Korea. The focus, however, should be on working towards peace on the Korean peninsula to prevent future provocations. The government intends to take various measures to address the public's worries. Kim Jong Un of North Korea expressed a desire to improve relations with South Korea, while the United States emphasized the need to increase pressure on North Korea to abandon its nuclear weapons. North Korea conducted numerous missile launches and its sixth nuclear test in violation of UN sanctions last year. It has been over two months since its most recent missile test in late November.
