Nuclear Suppliers Group
An organization of nuclear supplier nations which coordinates exports of nuclear materials and equipment with the International Atomic Energy Agency (IAEA) inspectorate regime. The reason for creating the NSG was to allow member states some flexibility (which they do not enjoy in the Zangger Committee) in controlling items to non-nuclear weapons states.
The NSG’s independence from the Nuclear Non-Proliferation Treaty (NPT) enables NSG to enlist the cooperation of supplier states that are not signatories to the NPT and thus not involved in the nuclear export control activities of the Zangger Committee. The NSG’s control list is more comprehensive than the Zangger Committee’s “trigger list”; it requires the imposition of safeguards on exports of nuclear technology in addition to nuclear materials and equipment.
