The UK hosted a conference of senior policy-makers, military officials and technical experts from the P5 (Russia, China, the US, the UK and France) on 3-4 September 2009 to consider the confidence building, verification and compliance challenges associated with achieving further progress on nuclear disarmament and non-proliferation.
The discussions covered ways to increase mutual understanding by sharing definitions of nuclear terminology and information about nuclear doctrines and capabilities; presentations on enhancing strategic stability; ways to build mutual confidence through voluntary transparency; and the international challenges associated with responding to nuclear accidents. The P5 undertook to consider ways to co-operate to address these challenges, and released a statement after the meeting.
