The Preparatory Committee for the 2020 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is scheduled to hold its second session from 23 April to 4 May 2018 at the United Nations Office in Geneva. This will be the second of three planned sessions that will be held prior to the 2020 Review Conference.

The Preparatory Committee, open to all States parties to the Treaty, is responsible for addressing substantive and procedural issues related to the Treaty and the forthcoming Review Conference. The Chair-designate of the second session is Ambassador Adam Bugaiski of Poland.

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.
