Deputy Assistant Secretary Frank Rose addresses ASEAN nonproliferation forum

Frank Rose, the deputy assistant secretary for the U.S. Department of State's Bureau of Arms Control, Verification and Compliance, delivered remarks on Tuesday at an Association of Southeast Asian Nations (ASEAN) forum in Tokyo, Japan.

Rose discussed U.S. nonproliferation efforts at the forum.

"The United States is and continues to be ready to work on all fronts toward a world free of nuclear weapons, in a step-by-step manner, pursuing-and creating-opportunities to reduce nuclear arsenals, increase confidence and transparency, and cooperate on nonproliferation," Rose said.

Rose cited the recent declassification of the amount of nuclear weapons in the U.S. arsenal, which has fallen by 85 percent since 1967 to 4,804 weapons. The deputy assistant secretary also said that increased monitoring and inspections of Russian and American stockpiles under the New Strategic Arms Reduction Treaty is vital to ensuring transparency between the world's largest nuclear powers.

Rose also highlighted multilateral efforts to reduce stockpiles and prevent the spread of weapons around the world, including U.S. support for the commencement of negotiations on a Fissile Material Cutoff Treaty and the Central Asian Nuclear Weapon Free Zone Treaty, which was signed last May.

The deputy assistant secretary also said that noncompliance by certain countries presents a challenge to nonproliferation efforts.
