South Korea Asserts Right to Peaceful Use of the DMZ

South Korea has the right to authorize peaceful use of the Demilitarized Zone separating the two Koreas, the country’s government legislation minister said Thursday, as Seoul seeks to clarify how sovereignty and access control apply inside the heavily restricted border area.

Government Legislation Minister Cho Won-cheol presented the position during a parliamentary audit of his agency. He said peaceful uses are permitted under the Korean War Armistice Agreement and argued that the southern half of the DMZ lies within South Korea’s sovereign jurisdiction.

The issue centers on differing interpretations of authority over entry into the zone. South Korea maintains that it may approve access when the purpose is peaceful. The United States-led United Nations Command has argued that control of access belongs to the UNC commander under the armistice that halted fighting in the 1950-53 Korean War. China, North Korea and the UNC signed that agreement; South Korea was not a signatory.

Cho said Seoul had long accepted, without sufficiently questioning it, the UNC’s position that South Korea lacked jurisdiction in the DMZ because it did not sign the armistice. The government has now begun discussions about peaceful use of the area as part of what he described as a proper exercise of South Korea’s rights.

According to Cho, the UNC does not deny South Korean sovereignty over the area and recognizes that its previous position went too far. He said the South Korean government has largely clarified its own interpretation of the armistice and communicated that position to the command. The UNC has since moderated its stance, he added.

Cho characterized the exchanges as producing a significant narrowing of differences between the two sides. His comments did not announce a new access arrangement or provide details of any specific project planned for the DMZ. They instead set out the government’s legal view and described progress in discussions with the command.

The distinction is important because the DMZ remains governed by the armistice framework while also encompassing territory that Seoul regards as falling under its sovereignty. Any broader civilian, environmental or other peaceful activity in the zone can therefore raise practical questions about who may authorize entry and how the armistice is applied.

The minister’s remarks indicate that Seoul is pressing for greater recognition of its authority over peaceful activity without rejecting the security arrangements that have regulated the DMZ since the fighting ended. Further details would be needed to determine how the narrowed gap in interpretation may affect future access decisions.
