Context: Japanese Prime Minister Sanae Takaichi, addressing the UN General Assembly in September 2026, called for the removal of the “enemy state” clauses from the UN Charter as part of broader UN and Security Council reforms.
- The demand comes amid increasing tensions with China and Russia, both of which have invoked these provisions while criticising Japan’s expanding defence capabilities and regional security policies.
What Are the Enemy State Clauses?
- The UN Charter, which entered into force on 24 October 1945, contains provisions concerning states that fought against the Allied Powers during World War II.
- Article 53(2) defines an enemy state as any state that was an enemy of a signatory of the UN Charter during World War II, primarily covering the defeated Axis Powers — Germany, Italy and Japan — and their allies.
- Article 53(1) provides an exception relating to enforcement action against former enemy states within the framework of regional arrangements, while Article 107 preserves actions taken or authorised by the governments responsible for the consequences of World War II.
- These provisions were introduced to prevent the resurgence of militarism and fascism in defeated Axis countries without requiring fresh Security Council authorisation for certain post-war actions.
Why Does Japan Want Their Removal?
- Japan argues that the clauses are outdated remnants of World War II and are inconsistent with its present status as a UN member and participant in the international security system.
- China and Russia have recently invoked the provisions in their diplomatic criticism of Japan, particularly concerning its defence expansion and regional security policies.
- China maintains that the clauses safeguard the post-war international order, while Russia has referred to them in the context of its territorial dispute with Japan over the southern Kuril Islands.
- Japan therefore seeks their formal deletion to prevent continued political use of provisions that have already been internationally recognised as obsolete.
Previous UN Efforts to Remove the Clauses
- In 1995, the UN General Assembly adopted a resolution recognising the enemy state clauses as obsolete, reflecting the changed international circumstances since World War II.
- In 2005, UN member states reaffirmed their intention to delete these references as part of broader UN reform.
- However, these declarations did not formally amend the Charter, and the provisions remain in its text despite their obsolete status.
Why Have the Clauses Not Been Removed?
- Article 108 of the UN Charter requires amendments to be adopted by a two-thirds majority of UN General Assembly members and ratified by two-thirds of UN members, including all five permanent members of the Security Council (P5).
- The P5 — the U.S., U.K., France, Russia and China — must therefore all ratify any amendment, giving each an effective ability to block its implementation.
- According to former Indian diplomat Manjeev Singh Puri, Japan's continued hosting of U.S. troops and reluctance among permanent members to reopen broader questions of UN reform have contributed to the delay.
- Some permanent members are concerned that amending the Charter could encourage further demands for UNSC reform, potentially affecting their existing institutional influence.
Rising Japan–China–Russia Tensions
- Taiwan: Relations between Japan and China deteriorated after Takaichi indicated in November 2025 that Japan could intervene militarily if China attacked Taiwan, which Beijing considers part of its territory.
- Economic pressure: China has restricted access to rare-earth magnets required by Japanese manufacturers, highlighting Japan's vulnerability in critical-mineral supply chains.
- Military tensions: China and Russia have conducted military exercises near Japan amid growing regional security competition.
- Territorial dispute: Japan and Russia continue to dispute sovereignty over the southern Kuril Islands, known in Japan as the Northern Territories. Takaichi criticised Russian President Vladimir Putin's reported August visit to the disputed islands.
- Diplomatic disagreements: China has defended the enemy state clauses as safeguards of the post-war international order, while Russia has invoked them in arguments concerning Japan's territorial claims.
Legal Status of the Enemy State Clauses
- Although the clauses remain in the Charter, their obsolescence was formally recognised by the UN General Assembly in Resolution 50/52 (1995).
- Their continued presence does not establish an unrestricted contemporary right to use military force against Japan; the provisions must be understood in their specific post-World War II context and alongside the Charter's general restrictions on force.
- Formal deletion would eliminate these historical references and reduce opportunities for their political invocation.
