Armistice Regime, Peace Regime, or Time for a Different Mindset on the Korean Peninsula?

Adopting a new mindset for peacebuilding on the peninsula requires preserving what works while targeting individual issues that remain unresolved. 

On the 73rd anniversary of the Korean Armistice Agreement late last month, South Korea’s Minister of Unification Chung Dong-young declared, “We must end the Armistice regime and move to a peace regime.” His statement echoed a promise from South Korean President Lee Jae-myung, who earlier in July promised South Korea’s Peace Unification Advisory Council that his administration would work to transition the Korean Peninsula away from the Armistice Agreement toward a “peace regime” paradigm. 

But what does this actually mean? What is a “peace regime” and is it attainable with North Korea?

These questions matter because they inform the trajectory of South Korea’s policy toward the North and, more fundamentally, how policymakers in Seoul approach peacebuilding on the peninsula.

In short, the “peace regime” is a long-standing South Korean policy design aimed at establishing a new framework for inter-Korean relations. The operative notion is to transition from the Armistice Agreement to an inter-Korean peace arrangement, to reduce foreign interference in the Korean peace process, and to establish interdependencies that would advance the two countries toward eventual reunification. 

While at times showing early promise during brief periods of rapprochement, this approach has ultimately been unable to achieve these objectives. This is principally owing to the fundamental mismatch with North Korea’s policy preferences and domestic politics in South Korea. But the treatment of the peace process as discrete phases also runs contrary to the basic principles of peacebuilding, installing arbitrary friction points and creating missed opportunities for shared cooperation.

Effective inter-Korean policy will eventually require a reframing of the peacebuilding efforts on the Korean Peninsula. This not only includes adapting to the Kim Jong Un regime’s decision to abandon unification as a policy objective, but also an evolution of internal South Korean politics that is currently in tension between different stakeholders. In the meantime, the Armistice Agreement will continue to provide a foundation from which peacebuilding efforts can proceed, just as it has for the past seventy-three years.

What the Armistice Actually Does

To understand Seoul’s desire to move beyond the armistice, it is first necessary to understand what the agreement does to support peace and stability on the peninsula.

The Korean Armistice Agreement is an interim agreement meant to maintain a cessation of hostilities and to give space for peacebuilding on the peninsula. It is therefore not incompatible with the peace process; rather, it is integral to it, as it provides a foundation for preserving a cessation of hostilities, institutionalizing the peace process, and creating opportunities for non-violent engagement. It does this through establishment of rights, duties, and obligations for both sides of the peninsula, designation of buffer areas such as the demilitarized zone (DMZ), and the institution of mechanisms for overseeing implementation of ceasefire provisions.

Although there have been notable violations of the armistice over the years, both sides by and large continue to abide by its rules today. On the north side, there is the Korean People’s Army (KPA) Panmunjom Mission, and on the south, there is the United Nations Command Military Armistice Commission (UNCMAC) staffed by countries including the United States, South Korea, Denmark, and New Zealand, among others. Switzerland and Sweden comprise the Neutral Nations Supervisory Commission (NNSC) and provide third party oversight.

The armistice mechanisms also provide an avenue for communication during periods when broader inter-Korean relations have broken down. Although North Korea ceased communication across inter-Korean channels in April 2023, the hotline between the UNCMAC and the KPA Panmunjom Mission has remained operational since September 2019. Moreover, both sides staff neutral ground at the Joint Security Area in Panmunjom, maintaining a constant presence to allow for both routine and crisis communications, as necessary. 

The practical importance of these mechanisms is easy to overlook because their most successful efforts are often invisible. It has been a tool for mitigating escalation cycles following the drone incursion incidents of 2022 and 2024, as well as lower level events such as the May 2020 exchange-of-fire between KPA and South Korean military forces inside the demilitarized zone.

There are limitations to the Armistice Agreement, which contribute to criticism among policy audiences in South Korea. The agreement does not establish mutually agreed maritime boundaries, which has been a factor in acute security incidents in the past and could enable grey zone competition in the future. North Korea’s refusal to allow the NNSC to operate in the northern half of the peninsula prevents on-the-ground oversight of its activities. Also, the boundary markers that were installed in the 1950s have faded. This has paved the way for accidental crossings in recent years as KPA forces carry out construction work in the northern half of the DMZ.

These are all notable shortcomings, but they all stem from the fact that the Armistice Agreement was never meant to be a final political resolution of the conflict. The armistice called for the convocation of a political conference within three months of its signing. That event was meant to deliver a political settlement of the war which would address all the outstanding issues necessary to restore a legal state of peace and normalization of relations. 

That conference ultimately took place in Geneva in 1954, but the parties could not resolve their fundamental disagreements, particularly over the future political status and unification of the peninsula. 

The armistice therefore remained in place.

This history is important because it demonstrates that the absence of a permanent peace agreement did not prevent peacebuilding from happening; rather, the armistice has provided space for it for the past seven decades.

The Pursuit of a “Peace Regime”

The South Korean conception of a “peace regime” came in the early 1990s. The two Koreas had both acceded to the United Nations and negotiated the “Agreement on reconciliation, nonaggression, exchanges and cooperation” — otherwise known as the “Basic Agreement.” This agreement included the following provision: “South and North Korea shall together endeavor to transform the present state of armistice into a firm state of peace........
