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.
2018 Korean peace process
On 27 April, a summit took place between Moon and Kim in the South Korean zone of the Joint Security Area. It was the first time since the Korean War that a North Korean leader had entered South Korean territory. North Korean leader Kim Jong-un and South Korea's President Moon Jae-in met at the line that divides Korea. The summit ended with both countries pledging to work towards complete denuclearization of the Korean Peninsula. They also vowed to declare an official end to the Korean War within a year. As part of the Panmunjom Declaration which was signed by leaders of both countries, both sides also called for the end of longstanding military activities in the region of the Korean border and a reunification of Korea. In 2018, a majority of South Koreans approved the new relationship. Also, the leaders agreed to work together to connect and modernise their railways.
