Leaders say working together on security crucial for stability

China and the United States pledged on Thursday to step up their cooperation in nuclear security.

In a joint statement, the two countries said they will work together to foster a peaceful and stable international environment by reducing the threat of nuclear terrorism and said they would strive for a more inclusive, coordinated, sustainable and robust global nuclear security architecture.

They applauded the successful completion of the first round of bilateral discussions on nuclear security that wrapped up on Feb 20 in Stockholm.
