Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons requires each of the Parties to the Treaty, both Non-Nuclear-Weapon States (NNWS) and Nuclear-Weapon States (NWS), to pursue effective measures relating to nuclear arms control and disarmament under strict and effective international control. The establishment of effective verification measures will be an important precondition for fulfilling the goals of Article VI.

The UK-Norway Initiative (UKNI) is a first-of-its-type collaboration between a NWS and a NNWS which supports the aims of Article VI by investigating the technical and procedural challenges of verifying possible future nuclear disarmament and arms control agreements. Beginning in 2007 and still operating to this day, the UKNI has successfully demonstrated how states can cooperate in this important and politically-sensitive area.
