Background
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.
Under the Treaty, the nuclear-weapon States are obliged not to transfer possession or control to any recipient nuclear weapons or other nuclear explosive devices, and not in any way to assist, encourage or induce non-nuclear-weapon States to manufacture, acquire or control over such weapons or devices. The non-nuclear-weapon States are obliged not to receive any transfer of or control over nuclear weapons or nuclear explosive devices, and not to manufacture or otherwise acquire such weapons or devices as well as not to seek or receive any assistance in this regard. The non-nuclear-weapon States further undertake to accept safeguards administered by the International Atomic Energy Agency on all source or special fissionable materials in all peaceful nuclear activities within their territory or under their jurisdiction or control, with a view to preventing diversion of nuclear energy from peaceful uses to nuclear weapons or other nuclear explosive devices.
The Treaty guarantees the right of all States parties develop research, production and use of nuclear energy for peaceful purposes without discrimination and in conformity with their basic non-proliferation obligations. Article VI of the NPT includes the only legally binding treaty-based obligation requiring States to pursue in good faith effective measures related to nuclear disarmament.
Conferences to review the operation of the Treaty have been held at five-year intervals since the Treaty went into effect in 1970. Each conference has sought to reach agreement on a final declaration that would assess the implementation of the Treaty’s provisions and make recommendations on measures to further strengthen it. Notably, the 2000 Review Conference agreed to a substantive final document, including practical steps for the systematic and progressive efforts to implement article VI of the Treaty on nuclear disarmament and the 2010 Review Conference produced conclusions and recommendations for follow-on actions in the areas of nuclear disarmament, nuclear non-proliferation, peaceful uses of nuclear energy and the Middle East, particularly implementation of the 1995 Resolution on the Middle East. The 2005, 2015 and 2020 Review Conferences were unable to reach agreement on any substantive outcome documents.
