The 2026 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons is taking place from 27 April to 22 May 2026 at United Nations Headquarters in New York.

The eleventh Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) concluded today without agreement on a consensus outcome document, even as the international community faces mounting and interrelated threats — from the spectre of nuclear weapons use in active conflicts, to attacks on nuclear facilities, to the destabilizing implications of emerging technologies, such as artificial intelligence (AI).

The following statement was issued today by the Spokesman for UN Secretary-General António Guterres:

With the risk of nuclear weapons use “at its highest since the darkest moments of the cold war”, United Nations delegates and representatives of international agencies and organizations today called for urgent efforts to reverse previous failures and deliver concrete results in disarmament and non-proliferation, as the eleventh Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) concluded its general debate.

Past nuclear tests cast a long shadow over the General Assembly Hall as the eleventh Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) entered its third day, with delegations grappling with the human and environmental toll that still echoes across generations.

With nuclear disarmament, deterrence and non-proliferation machinery stalled or imperilled, delegations today warned that the threat posed to humanity is not abstract but “real, present and growing”, as the eleventh Review Conference of the Parties to the Treaty on the Non‑Proliferation of Nuclear Weapons (NPT) entered its second day.

Following are UN Secretary-General António Guterres’ remarks to the eleventh Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, in New York today:

With humanity living under the shadow of potential nuclear Armageddon, United Nations Secretary‑General António Guterres today called on States to “breathe life” back into the Treaty on the Non‑Proliferation of Nuclear Weapons, stressing the urgent need to protect humanity from the grave threat of nuclear annihilation.
