A Message from the President-designate
The NPT is a landmark international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote co-operation in the peaceful uses of nuclear energy and to further the goal of achieving nuclear disarmament and general and complete disarmament. The NPT represents the only binding commitment in a multilateral treaty to the goal of disarmament by the nuclear-weapon States.
Opened for signature in 1968, the Treaty entered into force in 1970. Since its entry into force, the NPT has been the cornerstone of global nuclear non-proliferation regime. 191 States parties have joined the Treaty, including the five nuclear-weapon States, making the NPT the most widely adhered to multilateral disarmament agreement.
The Treaty, particularly article VIII, paragraph 3, envisages a review of the operation of the Treaty every five years, a provision which was reaffirmed by the States parties at the 1995 NPT Review and Extension Conference and the 2000 NPT Review Conference.
