I wonder if the North Koreans will demand payment for allowing searches for war remains inside their section of the DMZ?:

President Moon Jae-in said Wednesday he will push for the recovery of the remains of fallen soldiers in the Demilitarized Zone (DMZ) dividing the Koreas in line with the improvement of ties with the North.

In his address at the 63rd Memorial Day ceremony at the National Cemetery in Daejeon, he expressed hopes that the fresh detente will pave the way for inter-Korean joint efforts to account for tens of thousands of service members still listed as missing in action from the 1950-53 Korean War.

“We will continue efforts to recover the remains of military and police members who fell during the Korean War until we find the last remaining person,” the commander in chief said.

“When South-North relations improve, we will push for the recovery of the remains in the DMZ first of all. We will also be able to retrieve the remains of U.S. and other foreign soldiers who participated in the war.”  [Yonhap]
