North Korea–South Korea relations
In May 2017 Moon Jae-in was elected President of South Korea with a promise to return to the Sunshine Policy. In his New Year address for 2018, North Korean leader Kim Jong-un proposed sending a delegation to the upcoming Winter Olympics in South Korea. The Seoul–Pyongyang hotline was reopened after almost two years. At the Winter Olympics, North and South Korea marched together in the opening ceremony and fielded a united women's ice hockey team. As well as the athletes, North Korea sent an unprecedented high-level delegation, headed by Kim Yo-jong, sister of Kim Jong-un, and President Kim Yong-nam, and including performers like the Samjiyon Orchestra. The delegation passed on an invitation to President Moon to visit North Korea. Following the Olympics, authorities of the two countries raised the possibility that they could host the 2021 Asian Winter Games together. On 1 April, South Korean K-pop stars performed a concert in Pyongyang entitled "Spring is Coming", which was attended by Kim Jong-un and his wife. Meanwhile, propaganda broadcasts stopped on both sides.
