At the September 2018 inter-Korean summit, South Korean President Moon Jae-in and North Korean leader Kim Jong-un agreed to a joint operation to recover remains in part of the Korean Demilitarized Zone. The South Korean Ministry of National Defense estimated that the remains of approximately 200 South Korean soldiers, 100 American and French soldiers, and an unknown number of North Korean and Chinese soldiers are buried in the area. The remains of just over a thousand American troops are thought to be buried in or near the DMZ. On 28 July 2019, President Moon said once excavation was complete for Arrowhead Ridge, they would expand it to cover the whole of the DMZ.
