Preparatory Committee for the 2026 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT)

31 July – 11 August 2023 at Vienna International Centre

Press briefing now at 2 p.m. on Monday 31st July

UNITED NATIONS, 22 June 2023 – The first meeting of the Preparatory Committee for the 2026 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will be held at the Vienna International Centre in Vienna, Austria from 31 July - 11 August 2023. The Chair-designate of the first session is Ambassador Jarmo Viinanen of Finland.

The NPT entered into force in 1970 and was extended indefinitely in 1995. The Treaty is regarded as the cornerstone of the global nuclear non-proliferation regime and an essential foundation for the pursuit of nuclear disarmament. It was designed to prevent the spread of nuclear weapons, to further the goals of nuclear disarmament and general and complete disarmament, and to promote cooperation in the peaceful uses of nuclear energy.

The next Review Conference of the NPT will be held in 2026. In the three years leading up to that meeting, the Preparatory Committee convenes annually to consider principles, objectives and ways to promote the full implementation of the Treaty, as well as its universality, and to make recommendations to the Review Conference.

At this first Preparatory Committee meeting, States parties will consider specific matters of substance relating to the implementation of the Treaty and relevant decisions. The opening meeting will begin at 10 a.m. on Monday, 31 July, and will be held in the M-Plenary Conference Room (M-Building, first floor) at the Vienna International Centre.
