The concept of peaceful coexistence on the Korean Peninsula has been raised repeatedly over the past several decades. However, it has rarely been treated as a substantive policy priority. While its importance has consistently been acknowledged, sustained discussion and concrete implementation strategies have rarely followed. Underlying this persistent gap is a deeply rooted perception of the Korean Peninsula issue.

Until now, South Korea has approached inter-Korean relations not through the lens of “peaceful coexistence,” but rather through the dual paradigms of “division” and “unification.” There is no question that overcoming division and achieving unification remain important objectives and ultimate national goals. However, the predominance of unification-centered discourse has, paradoxically, pushed practical discussions of peaceful coexistence to the periphery.

The challenge is that this perception is becoming increasingly misaligned with evolving realities. Recent shifts in the domestic and international environment—such as North Korea’s articulation of “hostile relations between two states” and intensifying U.S.–China strategic competition—raise fundamental questions about the viability of a unification-first approach. In practical terms, peaceful coexistence has emerged not as a discretionary option, but as a minimum safeguard against mutual destruction and an existential necessity.

Under these conditions, treating unification as a short-term policy objective is increasingly untenable. It is therefore necessary to re conceptualize unification as a long-term, comprehensive endeavor while developing a strategy to manage the intervening period. At this juncture, peaceful coexistence is emerging not as a secondary consideration, but as an urgent and actionable policy priority.

Accordingly, what is required is a shift in perspective that moves peaceful coexistence from a declaratory concept to the center of operational policy. Peaceful coexistence is not a substitute for unification, but rather the foundational order of the Korean Peninsula that must be effectively managed within a broader unification framework.

Envisioning unification without a parallel process to prevent conflict and build trust is difficult to justify from both practical and strategic standpoints. Ultimately, the design and implementation of peaceful coexistence constitute the most viable pathway toward unification and the central task of Korean Peninsula policy.

To sustainably realize peaceful coexistence, domestic public support, the cultivation of an inter-Korean cooperative environment, and robust international cooperation are essential. In particular, international cooperation presents unique challenges, as it requires coordination with external actors whose national interests may diverge from those of South Korea, thereby limiting Seoul’s degree of control. While it is both natural and necessary for South Korea to seek a leading role in addressing these issues, the division of the Korean Peninsula is inextricably linked to broader international dynamics.

It is therefore a geopolitical reality that the issue cannot be resolved through unilateral approaches that exclude cooperation with external stakeholders. International cooperation is thus not optional, but a prerequisite for the effective functioning of peaceful coexistence. The development of sophisticated diplomatic strategies, coupled with effective implementation, will be a critical variable.

Only by fostering a conducive environment within a multi-layered framework of international cooperation—encompassing neighboring states such as the United States, China, Japan, and Russia, as well as international organizations and civil society networks—can the sustainability and credibility of peaceful coexistence be ensured.

Furthermore, peaceful coexistence must be redesigned as a multi-layered cooperative architecture in which collaboration across diverse sectors is mutually reinforcing, rather than dependent on a single policy initiative or agreement. The first layer consists of health cooperation and humanitarian medical assistance.

Joint responses to infectious diseases, the prevention of tuberculosis and malaria, support for essential medicines and medical equipment, cooperation on maternal and child health and nutrition, and emergency medical coordination during disasters are areas that carry relatively low political sensitivity while directly enhancing human security. Such initiatives can serve as practical entry points for peaceful coexistence by restoring working-level engagement, building trust, and establishing cooperative platforms that enable participation by international organizations and third countries.

The second layer involves climate response and cooperation in the environmental and forestry sectors. Climate change represents a structural challenge requiring collective action irrespective of political or military tensions, and the Korean Peninsula faces a range of environmental risks, including floods, droughts, heatwaves, air pollution, and deforestation. In particular, deforestation in North Korea constitutes an urgent area for cooperation, given its implications for ecosystem degradation, food insecurity, and disaster vulnerability.

Inter-Korean forest restoration initiatives, joint water resource management, disaster response coordination, and climate data sharing can generate tangible outcomes even under relatively constrained political conditions. Such environmental cooperation is also likely to attract broad international support and serves as a critical pillar for enhancing the sustainability of peaceful coexistence.

The third layer entails cooperation in religion, culture, and education aimed at fostering social trust. Peaceful coexistence cannot be sustained solely through intergovernmental agreements; it requires the gradual accumulation of societal engagement and interpersonal exchange. Religious organizations can serve as important channels for expanding inter-Korean contact through the promotion of humanitarian and reconciliation-oriented values.

Joint preservation of cultural heritage, exchanges in the arts and performing arts, and cooperation in traditional culture can help mitigate entrenched hostility. In addition, educational exchanges, academic collaboration, and youth engagement programs represent long-term investments in shaping future perceptions. The cumulative effect of such non-political cooperation is essential for embedding peaceful coexistence as a lived social reality rather than a purely policy-driven construct.

These initial layers of cooperation involve relatively low political risk and are more conducive to securing international support, thereby playing a critical role in establishing the foundations of peaceful coexistence. However, peaceful coexistence cannot be sustained if it remains confined to these levels. For cooperation to become durable, it must evolve toward the integration of mutual interests. Once a baseline level of trust has been established, cooperation should expand into more structurally and strategically significant domains.

Accordingly, economic cooperation is most appropriately positioned as the fourth layer. Economic engagement extends beyond functional cooperation to generate interdependencies that increase the costs of conflict for both parties. Infrastructure development, energy cooperation, industrial collaboration, and the operation of special economic zones can produce tangible mutual benefits. As economic interdependence deepens, incentives for military confrontation decline correspondingly. This stage is essential for establishing the material foundations of peaceful coexistence.

The fifth layer encompasses military cooperation. While inherently sensitive, the military domain is indispensable for managing tensions and preventing escalation. Measures such as the restoration of military communication channels, the establishment of mechanisms to prevent accidental clashes, and enhanced transparency can serve as practical confidence-building measures. Military cooperation thus functions not only as a mechanism for tension reduction but also as a structured framework for risk management that reduces the probability of conflict to manageable levels.

The sixth layer involves political coexistence. This stage focuses on establishing institutional frameworks for mutual recognition and conflict management. Key elements include refraining from mutual defamation, institutionalizing sustained dialogue mechanisms, and developing crisis management frameworks. Over time, such measures may contribute to the establishment of a durable peace regime. Although political cooperation requires a high degree of political commitment, it remains an essential step in consolidating peaceful coexistence as a stable and institutionalized order.

In sum, peaceful coexistence on the Korean Peninsula should be understood as a multi-layered cooperative architecture in which diverse domains operate both sequentially and, at times, concurrently. As the scope and density of cooperation expand, the system becomes more resilient to shocks in any single domain.

If the process is narrowly concentrated on military or political issues at the outset, progress may remain fragile and vulnerable to disruption from shifts in the political environment. Ultimately, the sustainability of peaceful coexistence depends not only on deterrence, but also on the density of social linkages, the institutionalization of cooperative mechanisms, and the breadth of international support.

The task ahead is to institutionalize this cooperation not as a series of ad hoc initiatives, but as a sustainable system. This requires securing flexible pathways for engagement while maintaining alignment with the broader international system. It also requires elevating cooperation beyond assistance-based models toward frameworks that enhance joint response capacity and mutual trust.

Ultimately, the success or failure of peaceful coexistence on the Korean Peninsula will depend on both a transformation in strategic thinking and the effectiveness of institutional design. Peaceful coexistence cannot be sustained through declarations alone; it must be constructed through the cumulative development of multi-layered international cooperation. In an era in which unification is appropriately framed as a long-term objective, the design and implementation of peaceful coexistence constitute the central strategic task shaping the future of the Korean Peninsula.
