Nuclear Nonproliferation Treaty


Overview

The Treaty on the Nonproliferation of Nuclear Weapons (NPT) is the cornerstone of the nonproliferation regime; it entered into force in 1970 and includes 190 states party. 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.

The NPT Review Process

The Treaty allows for the Parties to gather every five years to review its operation. At the 1995 Review and Extension Conference, the Parties extended the Treaty indefinitely and formalized the practice of convening a Review Conference (RevCon) every five years, as well as holding Preparatory Committee (PrepCom) meetings in each of the three years preceding a RevCon. The 2014 PrepCom for the 2015 NPT RevCon will take place at the United Nations headquarters in New York from April 28-May 9 under the Non-Aligned Movement Chairmanship of Peruvian Ambassador Enrique Román-Morey. This will be the third meeting of the review cycle that will culminate in the 2015 NPT Review Conference.
