Leaders from 47 countries gathered in Washington in April 2010, to address the
issue of nuclear security for the first time amid rising concerns over nuclear materials getting into the hands of terrorists.
The Nuclear Security Summit was launched a year after US President Barack Obama announced his four-year vision in Prague, to end the spread of nuclear weapons and secure nuclear materials
In the Washington Communique, participating nations pledged to realize together President Obama's vision, and each improve their own nuclear security and accounting of nuclear materials.
The International Atomic Energy Agency was urged to develop nuclear security guidelines, and ensuring security assistance was also highlighted.
And in just 1-hundred days, the Korean capital city of Seoul will host the second Nuclear Security Summit.
With some 50 heads of state and leaders from four international organizations in attendance, the Seoul Summit will also address nuclear safety in response to Japan's Fukushima nuclear meltdown in March of this year.
