A lot has changed since the leaders of the two Koreas have met on April 27, 2018 to engage in peace talks which laid the foundation for their Comprehensive Military Agreement which was signed at the second summit by the two countries on September 19th.
It included the trial removal of nearly a dozen frontline guardposts on both sides of the Demilitarized Zone as well as the removal of weaponry and troops there following trilateral military talks held with the United Nations Command in October last year.
Since the inter-Korean military agreement, the two Koreas have also disarmed the Joint Security Area in Panmunjeom and set up ground, air and maritime buffer zones along the inter-Korean border.
A no-fly zone has been imposed covering 10 to 40 kilometers from the Military Demarcation Line and Seoul's defense ministry has been trying to negotiate with the North about expanding the zone to cover the Hangang river estuary.
The two Koreas have also carried out a joint survey of the estuary's waterway with the aim of providing free passage of civilian vessels by sharing the area.
They have also conducted demining operations at Arrowhead Ridge inside the DMZ site to one of the fiercest battles during the Korean War for the excavation of troop remains.
Despite this, the two Koreas still have a long way to go to fully implement the agreement amid deepening concerns over Pyeongyang's increasingly lukewarm attitude amid a lack of progress in denuclearization talks with the U.S.
Further discussions include North Korea's acknowledgement of the Northern Limit Line, the disputed maritime demarcation line in the West Sea where the Koreas have agreed to establish a shared fishing ground.
They also need to hold more talks on the joint excavation of war remains currently being carried out solely by the South after the North failed to respond.
