Many state leaders will gather at the fourth Nuclear Security Summit in Washington to discuss international nuclear security issues. President Xi Jinping put forward China's outlook on nuclear security for the first time at The Hague Nuclear Security Summit in the Netherlands in 2014, which has become an important concept guiding the country's efforts to strengthen nuclear security.

That Xi will also attend this year's summit in Washington demonstrates China's willingness to implement the new outlook on nuclear security and its sense of responsibility when it comes to global nuclear security.

The spread of terrorism has aggravated the risks of international nuclear terrorism. So the international community has to strengthen coordination and global governance in the nuclear field.
