The third Nuclear Security Summit in The Hague came to a close on Tuesday with the 53 countries taking part adopting a communique.
At this year's summit, world leaders focused on measures to prevent terrorists, criminals and unauthorized personnel from obtaining nuclear materials that could be used in developing nuclear weapons.
They also urged countries that have not done so yet to become a party to the Convention of the Physical Protection of Nuclear Material, a key international legal body that addresses nuclear security issues.
The leaders also vowed to make continuous efforts to achieve the common goal of strengthening international nuclear security architecture.
The next summit will take place in 2016 in the United States.
