South Korea’s description of the two Koreas as existing as “de facto two states” marks a significant change in how Seoul presents its North Korea policy. The wording does not formally abandon the constitutional objective of peaceful unification. Instead, it attempts to recognize the peninsula’s present division while prioritizing peaceful coexistence, mutual respect, and gradual engagement.
What Changed in the Unification White Paper?
South Korea’s 2026 unification white paper describes the South and North as existing in the reality of “de facto two states.” It defines the desired relationship as a peaceful two-state relationship oriented toward eventual unification rather than a permanently hostile division.
The document also presents three guiding principles: respecting North Korea’s political system, rejecting unification by absorption, and refraining from hostile acts. These principles are intended to reassure Pyongyang that dialogue would not be used as an immediate instrument of regime change.
The language distinguishes between recognizing two separately governed states in practice and legally accepting permanent national division as the final objective. Seoul’s position therefore remains different from North Korea’s hostile two-state doctrine.
Does This Mean South Korea Accepts Permanent Division?
Not necessarily. South Korea’s Constitution defines the national territory as the Korean Peninsula and its adjacent islands. It also requires the state to formulate and implement a policy of peaceful unification based on the principles of freedom and democracy.
An annual policy white paper does not have the same legal effect as a constitutional amendment or an intergovernmental treaty. The two-state terminology is better understood as an administrative and diplomatic framework for managing current relations.
| Issue | Traditional Framework | New Policy Language |
|---|---|---|
| Current relationship | A nation temporarily divided during the process of unification | Two de facto states requiring peaceful coexistence |
| Immediate priority | Preparing for eventual unification | Preventing conflict and rebuilding communication |
| North Korean system | A counterpart within a divided nation | An existing system to be respected for dialogue and coexistence |
| Long-term objective | Peaceful unification | Peaceful unification following stable coexistence |
The central question is whether peaceful coexistence will remain a practical stage toward unification or gradually become the lasting objective of inter-Korean policy.
How North Korea Changed Its Position
North Korea began openly rejecting the traditional concept of one Korean nation moving toward reunification after Kim Jong Un declared that relations had become those of two hostile states. It dismantled or renamed institutions and symbols associated with inter-Korean unity and increasingly presented South Korea as a separate enemy state.
North Korea first confirmed in 2024 that its revised constitutional framework identified South Korea as a hostile state. A constitution publicized in 2026 went further by removing its previous reunification objective and adding a territorial provision referring to a southern border.
Seoul’s approach is partly a response to this change. South Korea is attempting to transform the concept of two hostile states into peaceful coexistence between two de facto states without formally abandoning its own constitutional commitment to unification.
What Seoul Is Trying to Achieve
The immediate purpose of the policy is not rapid political integration. Its focus is reducing military risk, restoring communication, and creating conditions in which limited cooperation could eventually resume.
- Restoring official and military communication channels
- Reducing the risk of accidental clashes near the border
- Resuming humanitarian cooperation and separated-family contacts
- Rebuilding civilian, economic, and social exchanges when conditions permit
- Creating a longer-term structure for arms control and nuclear negotiations
This approach assumes that stable coexistence must be established before more ambitious objectives can be pursued. It also recognizes that immediate demands for political transformation or complete denuclearization have not produced a durable settlement.
Possible Advantages of the New Approach
Treating North Korea as an existing negotiating counterpart may make communication more practical. Pyongyang has frequently interpreted South Korean calls for unification as possible language for absorption, particularly when those calls have been accompanied by pressure for internal change.
A commitment not to pursue absorption could reduce one source of insecurity for the North Korean leadership. It may also allow both governments to discuss border management, humanitarian matters, and military risk without first agreeing on the peninsula’s ultimate political structure.
- Realism: The approach acknowledges that the two Koreas have maintained separate governments, economies, institutions, and social identities for decades.
- Risk reduction: It places the prevention of war ahead of symbolic competition over political legitimacy.
- Policy flexibility: It permits gradual agreements without requiring an immediate settlement of the unification question.
- Reassurance: It may weaken claims that engagement is intended to undermine or absorb North Korea.
Political and Strategic Risks
The approach also faces substantial limitations. North Korea could welcome language that confirms its separate existence while rejecting the reciprocal restraint, transparency, and cooperation expected by Seoul.
Critics argue that two-state terminology could normalize permanent division, weaken South Korea’s constitutional position, or concede an important political demand without receiving anything in return. They also question whether assurances of non-hostility can influence North Korean behavior while Pyongyang continues expanding its nuclear and missile capabilities.
| Potential Benefit | Corresponding Risk |
|---|---|
| More realistic diplomatic terminology | Permanent division could become normalized |
| Reduced fear of absorption | North Korea could interpret restraint as weakness |
| Greater opportunity for dialogue | Talks could proceed without meaningful concessions |
| Lower military tension | Deterrence could suffer if engagement is not balanced |
| Gradual nuclear negotiations | Interim agreements could legitimize an enduring nuclear arsenal |
Peaceful terminology cannot create stable peace by itself. A sustainable framework would also require credible deterrence, crisis-management mechanisms, verification, and reciprocal action.
How Denuclearization Fits Into the Policy
South Korea has not formally abandoned the objective of denuclearization. The government has promoted a phased process that begins with stopping the expansion of North Korea’s nuclear and missile programs.
The proposed sequence is generally described as a freeze, reduction, and eventual dismantlement or denuclearization. The first stage would seek to prevent further expansion, the second would reduce existing capabilities, and the final stage would pursue the elimination of the nuclear program.
This is more gradual than demanding complete disarmament at the beginning of negotiations. However, it faces the fundamental problem that North Korea describes its nuclear status as irreversible and treats nuclear weapons as essential to state security.
A phased agreement could reduce immediate danger even if complete denuclearization remains distant, but weak verification could allow North Korea to preserve or secretly expand parts of its arsenal. Monitoring, reciprocity, and clear consequences for violations would therefore be essential.
Public Opinion and the Future of Unification
South Korean attitudes toward unification have changed as the division has continued. Older generations were more likely to have direct memories of war, displacement, or separated relatives. Many younger citizens instead evaluate unification through economic cost, employment, taxation, security, and social integration.
Support for or opposition to rapid unification cannot be classified entirely along a simple left-right divide. Progressive voters may favor engagement while opposing absorption, whereas conservative voters may support national unity while rejecting concessions to Pyongyang.
A meaningful public debate would need to distinguish among several possible outcomes:
- Long-term coexistence between two states
- A confederation with separate political systems
- Gradual integration over several decades
- Unification following major political change in North Korea
- Emergency integration after an unexpected collapse
These scenarios involve different legal arrangements, security consequences, and economic costs. Public support for “unification” can therefore be difficult to interpret unless surveys explain the form and conditions being considered.
What the Policy Could Mean for North Korean Defectors
The use of two-state terminology in a policy document does not automatically remove the protections available to North Korean defectors. Their legal treatment is based on South Korean constitutional interpretation and legislation rather than solely on the language of an annual white paper.
North Korean defectors who satisfy the applicable requirements can continue to receive legal recognition and settlement assistance under the existing system. A fundamental change would likely require significant legislative, judicial, or constitutional action.
Formal recognition of North Korea as a permanently separate foreign state could eventually raise difficult questions involving nationality, citizenship, asylum, and diplomatic relations. The current white paper does not resolve those broader legal issues.
An Objective View
South Korea’s new terminology is best understood as an attempt to separate immediate peace management from the distant objective of unification. It recognizes that the two governments function as separate states while maintaining that peaceful integration could remain a future possibility.
The policy may create more space for communication because it reduces the emphasis on regime change and absorption. Its success, however, depends on whether North Korea responds with restraint rather than accepting only the elements that reinforce separation.
Military pressure alone has not resolved the conflict, but dialogue alone has also failed to stop North Korea’s nuclear development. A durable strategy would need to combine deterrence, diplomacy, humanitarian engagement, crisis prevention, and realistic nuclear-risk reduction.
The most important test is not whether the framework is labeled one-state or two-state, but whether it reduces the danger of war while protecting South Korea’s security, democratic principles, and ability to influence the peninsula’s long-term future.
