The 2017 Preparatory Committee (PrepCom) for the 2020 NPT Review Conference (RevCon) took place at the Vienna International Centre from May 2-12 under Chair-designate Ambassador Henk Cor Van der Kwast of the Netherlands. This was the first of three planned sessions to be held prior to the 2020 Review Conference.

The Treaty on the Nonproliferation of Nuclear Weapons is the cornerstone of the nonproliferation regime. It entered into force in 1970, and 190 states have subscribed. The treaty covers three mutually reinforcing pillars—disarmament, nonproliferation, and peaceful uses of nuclear energy—and is the basis for international cooperation on stopping the spread of nuclear weapons. The basic bargain at the core of the NPT is sound: Countries with nuclear weapons will move towards disarmament; countries without nuclear weapons will not acquire them; and all countries can access peaceful nuclear technology.
