The first Nuclear Security Summit was held in Washington, DC in 2010, and was followed by additional Summits in Seoul in 2012 and The Hague in 2014. These Summits have achieved tangible improvements in the security of nuclear materials and stronger international institutions that support nuclear security.
The summits bring together heads of states to focus on the critical issue of reducing risks from fissile materials proliferation. The summit in 2016 will be the last. It therefore holds a special significance: the NSS process is ending, but nuclear security requires sustained vigilance and continuous progress.
Heads from 52 countries and international organizations will participate in the 2016 summit in Washington on March 31 and April 1.
