U.S. Secretary of State Hillary Clinton says strengthening the global nonproliferation regime means working to bring North Korea and Iran into compliance.

Clinton made the remark during a speech at the Brookings Institution in Washington on Friday.

She added that next week President Barack Obama will chair a meeting of the U.N. Security Council on nonproliferation and disarmament. He will emphasize the importance of strengthening the international nuclear nonproliferation regime and the critical role that the Security Council must play in enforcing compliance with nonproliferation obligations.
