The 11th Review Conference of the Parties to the Treaty on the Non-Proliferation of nuclear weapons concluded in New York City in May 2026 without achieving consensus on an outcome document.
The Treaty on the Non-Proliferation of nuclear weapons (NPT) aims to prevent the spread of nuclear weapons, promote the peaceful use of nuclear energy, and support nuclear disarmament.
The European Union said the NPT remains the cornerstone of the global nuclear non-proliferation regime and international peace and security.
Major concerns discussed included Russia’s nuclear threats linked to Ukraine, the Democratic People’s Republic of Korea (DPRK) nuclear and missile programme, and China’s rapid nuclear build-up.
The conference also supported stronger transparency measures and improvements in reviewing treaty obligations of member countries.
