Canadian Prime Minister Stephen Harper announced five objectives for Nuclear Security Summit on Friday before he departs for the meeting dated April 12-13 in Washington, the United States. These objectives are to underscore the seriousness of the nuclear terrorist threat, to encourage states to strengthen their national nuclear security measures to enhance physical protection measures applied to nuclear material and facilities, to increase international cooperation on nuclear security, to endorse and contribute to U.S. President Barack Obama's 4-year effort to secure all vulnerable nuclear material worldwide, and to ensure the Summit supports broader non-proliferation and disarmament efforts. 'The Nuclear Security Summit will provide Canada with an opportunity to highlight Canadian leadership on nuclear security and its cooperation with the United States and other partners to ensure that all nuclear materials are secure so that they do not fall in the hands of terrorists,' said Harper. 'Through our G-8 Presidency in 2010, Canada is in a position to play a leading role in implementing the delivery of the key outcomes of the Nuclear Security Summit,' added the Prime Minister. Representatives from 47 countries, including all G-8 and G-20 members, have been invited to attend the Summit. They will discuss nuclear terrorism and the pressing need to further develop and implement internationally-coordinated efforts to enhance nuclear security worldwide.
