The Nuclear Nonproliferation Treaty (NPT) is the only multilateral treaty with the goal of creating a binding commitment of disarmament by nuclear-weapon states. NPT seeks to promote cooperation in the field of peaceful nuclear technology and prevent the spread of nuclear weapons and weapons technology. More states have ratified the NPT than any other treaty on arms limitation and disarmament. Every five years, the Treaty’s operations are reviewed. The International Atomic Energy Agency (IAEA) verifies compliance with the Treaty.
