On 27 April, the 2018 inter-Korean summit took place between President Moon Jae-in and Kim Jong-un on the South Korean side of the Joint Security Area. It was also the first time since the Korean War that a North Korean leader had entered South Korean territory. The summit ended with both countries pledging to work towards complete denuclearization of the Korean Peninsula. They agreed to work to remove all nuclear weapons from the Korean Peninsula and, within the year, to declare an official end to the Korean War. 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. Also, the leaders of the region's two divided states have agreed to work together to connect and modernise their border railways.
