The Government's work in raising awareness of the scale and nature of the nuclear threat posed by the actions of the Democratic People's Republic of Korea (DPRK) helped UN Resolution 1718 to pass quickly through the UN Security Council. The UK was able to inform discussions about what actions the international community would be able to take. Resolution 1718 made clear that the DPRK should: cease immediately all further nuclear testing; observe a moratorium on nuclear and missile testing; and return to the Treaty on the Non-Proliferation of Nuclear Weapons, and International Atomic Energy Agency (IAEA) safeguards, thus enabling IAEA inspectors back in to the DPRK and reports to be made on its facilities.
Under the Nuclear Non- Proliferation Treaty (NPT), a nuclear weapon state is defined as a state which manufactured and exploded a nuclear weapon or other nuclear explosive device prior to 1 January 1967. Nuclear weapon states are defined under Article IX.3 of the NPT; these are the UK, US, France, China and Russia. The Democratic People's Republic of Korea (DPRK) already possesses nuclear fuel cycle capabilities and a civil nuclear power generating programme. And on 14 October 2006, following a partially successful nuclear test, the UN Security Council adopted resolution 1718 urging the DPRK to cease immediately all further nuclear testing, observe a moratorium on nuclear and missile testing and rejoin the NPT.
