Military Demarcation Line
On 27 April 2018, during the 2018 Inter-Korean Summit, the Panmunjom Declaration for Peace, Prosperity and Reunification of the Korean Peninsula was adopted between the Supreme Leader of North Korea, Kim Jong-un and the President of South Korea, Moon Jae-in. Later that same year, following the September Inter-Korean Summit, several actions were taken toward reunification along the border, such as the dismantling of guard posts and the creation of buffer zones to prevent clashes. On 12 December 2018, soldiers from both Koreas crossed the Military Demarcation Line (MDL) into the opposition countries for the first time in history.
