Kim Yong Chol, vice-chairman of the North Korean ruling Workers' Party's Central Committee, will lead a high-level delegation at the Winter Olympics closing ceremony in Pyeongchang on Sunday. The delegation will also meet with President Moon Jae-in. Kim Yong Chol was previously the head of the Reconnaissance General Bureau, a top North Korean military intelligence agency that South Korea accused of being responsible for the 2010 sinking of the Cheonan. North Korea has denied any involvement in the incident. Despite the controversy, the South Korean Unification Ministry has stated that they are focusing on the potential for peace and improved inter-Korean relations through dialogue with the visiting North Korean officials, rather than dwelling on their past actions or identities. Kim's upcoming visit will coincide with Ivanka Trump's visit to South Korea as well. Ivanka is set to arrive later on Friday to have dinner with Moon and attend the Winter Olympics' closing ceremony. The Blue House has stated that there are no official plans for U.S. and North Korean officials to meet. South Korea's recent decision to allow Kim, who is currently under sanctions from the United States and South Korea, to cross the border has caused backlash from the families of the deceased Cheonan sailors and opposition parties. Members of the main opposition Liberty Korea Party held a protest in front of the Blue House, demanding the government reverse its decision. The party criticized President Moon's acceptance of North Korea's peace efforts, calling it a serious issue and a crime. A group of relatives of the victims of the Cheonan sinking has announced plans to hold a press conference to protest the decision on Saturday. Despite public concerns about Kim's upcoming visit, Baik emphasized that South Korea's position on the Cheonan sinking, which blames North Korea, remains unchanged. Baik also stressed the importance of working towards genuine peace on the Korean peninsula to prevent such provocations in the future. The government is committed to addressing the public's worries through various efforts. North Korean leader Kim Jong Un has expressed a desire to enhance reconciliation and dialogue with South Korea following the Winter Olympics, while the United States is pushing for increased pressure on North Korea to abandon its nuclear weapons. Despite facing UN sanctions, North Korea conducted numerous missile launches and its largest nuclear test last year. It has been over two months since the last missile test was conducted in late November.
