World leaders gathered at The Hague for the third Nuclear Security Summit, an opportunity to compare notes on how far we’ve come and chart the course ahead as we work to keep sensitive materials -- the building blocks of nuclear weapons -- from falling into the wrong hands. 

During the meeting Belgium and Italy announced the completion of significant removals of highly-enriched uranium (HEU) and plutonium, and Japan made a major new commitment to remove highly enriched uranium and plutonium from its territory.  

Progress has been made since the first Summit in 2010 but there is much more to be done.
