Chinese President Xi Jinping Tuesday called for a fair, cooperative and win-win system of global nuclear security.

Xi made the call during a panel discussion on the second day of the third Nuclear Security Summit (NSS), adding that the NSS is of great significance for nuclear security worldwide as it bears the task of "blueprinting the future."

"Looking into the future, we need to inject lasting momentum into the nuclear security process, put it on a sustainable track with a proper mechanism, and gradually set up a fair, cooperative and win-win international nuclear security system," said the Chinese president.

Xi proposed that under the principle of fairness, all countries concerned should assume due obligations in line with their national situation, and enhance capability to safeguard nuclear security based on the balance of rights and obligations.

The International Atomic Energy Agency (IAEA) should work as a core platform, supplemented by other multilateral mechanisms and initiatives, in the establishment of a comprehensive, multilevel and networked system of global nuclear security, Xi said.

"The IAEA's role in nuclear security should be strengthened, and there should be real assistance offered to developing countries in their efforts of building nuclear security capability," he said.

The president also proposed that the international community should unswervingly safeguard nuclear security while developing nuclear energy, and share the benefit in the peaceful use of nuclear energy, thus realize security and sustainable development for countries across the world.

When addressing the nuclear terrorism threat, Xi stressed that all countries concerned should work together to prevent and combat nuclear terrorism in all forms.

The NSS ended Tuesday in The Hague, the Netherlands, with a joint communique. The next summit will be held in the United States in 2016.
