Pillar 2

Non-Proliferation

Preventing the spread of nuclear materials and technologies for military purposes

of the 64-item Action Plan agreed to by NPT States

Pillar 2 of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) establishes strict non-proliferation obligations for both nuclear-weapon and non-nuclear-weapon States. Nuclear-weapon States must not transfer nuclear weapons, nuclear explosive devices, or control over them, nor assist or encourage any non-nuclear-weapon State to acquire or manufacture such weapons. Correspondingly, non-nuclear-weapon States commit not to receive, manufacture, or seek assistance in acquiring nuclear weapons or explosive devices.

To ensure compliance, non-nuclear-weapon States must accept international safeguards administered through agreements with the International Atomic Energy Agency (IAEA), covering all nuclear material used for peaceful purposes within their jurisdiction or control. States are prohibited from supplying sensitive nuclear materials or equipment to non-nuclear-weapon States unless these are subject to safeguards. These measures are designed to prevent diversion to weapons while supporting peaceful nuclear cooperation and technological development, with safeguard agreements to be negotiated and brought into force within specified timeframes after joining the Treaty.
