Kim Yo-jong
In his 2018 New Year Speech, Kim announced that he was open to dialogue with South Korea with a view to take part in the upcoming Winter Olympics in the South. The Seoul–Pyongyang hotline was reopened after almost two years. North and South Korea marched together in the Olympics opening ceremony, and fielded a united women's ice hockey team. In addition to the athletes, Kim sent an unprecedented high-level delegation including his sister, Kim Yo-jong, and President of the Presidium, Kim Yong-nam, and performers such as the Samjiyon Orchestra. On 5 March, he had a meeting with South Korea's Chief of the National Security Office, Chung Eui-yong, in Pyongyang.
