The United States continues to try to find ways to reduce nuclear and security risks with China through bilateral dialogue as well as via the so-called P5 Process, said Bonnie Jenkins, the U.S. State Department's top arms control official, during a recent telephone interview.

The remarks by the undersecretary of state for arms control and international security came several days after the United States, Russia, China, France and Britain issued a joint statement affirming that a war involving nuclear weapons must be avoided and that such armaments should serve defensive purposes and deter aggression.

The five nuclear weapon states are permanent members of the U.N. Security Council — called the "P5" — with each wielding veto power over crucial decisions related to international security.
