Kim Yong Chol, the vice-chairman of the North Korean ruling Workers' Party's Central Committee, will lead a high-level delegation to attend 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 held responsible for the fatal sinking of the Cheonan, a South Korean navy corvette, in 2010. North Korea has denied any involvement in the incident. Despite these circumstances, the South Korean Unification Ministry, represented by Baik Tae-hyun, has emphasized the importance of focusing on the potential for peace on the Korean peninsula and improvements in inter-Korean relations that could result from 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, where she is scheduled to attend a dinner with Moon and the Winter Olympics' closing ceremony. The Blue House has stated that there are no official opportunities for U.S. and North Korean officials to meet. South Korea's decision to allow Kim to cross the border, despite being sanctioned by the United States and South Korea, has sparked protests from family members of the dead Cheonan sailors and opposition parties. The main opposition Liberty Korea Party staged a protest in front of the presidential Blue House, demanding the government withdraw its decision, calling it a serious issue that will be remembered as a crime eternal. A group of relatives of the victims of the Cheonan sinking will hold a press conference to voice their opposition to the decision on Saturday. Despite public concern regarding Kim's upcoming visit, Baik emphasized that South Korea's position that North Korea was responsible for the sinking remains unchanged. Baik stated that the focus should be on efforts to establish lasting peace on the Korean peninsula to prevent similar incidents in the future. The government plans to take various actions to address the public's worries. Kim Jong Un of North Korea expressed a desire to improve relations with South Korea following the Winter Olympics, while the United States emphasized the importance of increasing pressure on North Korea to denuclearize. North Korea defied UN sanctions last year by conducting numerous missile launches and its largest nuclear test. It has been over two months since the last missile test took place in late November.
