Foreign relations of North Korea
In 2017 Moon Jae-in was elected President of South Korea with promises 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. North and South Korea marched together in the Olympics opening ceremony and fielded a united women's ice hockey team. North Korea sent an unprecedented high-level delegation, headed by Kim Yo-jong, sister of Kim Jong-un, and President Kim Yong-nam, as well as athletes and performers.

On 9 February 2018, Kim attended the 2018 Winter Olympics opening ceremony in Pyeongchang, South Korea. This was the first time that a member of the ruling Kim dynasty had visited South Korea since the Korean War. She attended the meeting with South Korean President Moon Jae-in on 10 February, and revealed she was dispatched as a special envoy of Kim Jong-un and delivered a personally written letter from Kim to Moon.
