The U/S also leads the interagency policy process on nonproliferation and manages global U.S. security policy, principally in the areas of nonproliferation, arms control, regional security and defense relations, and arms transfers and security assistance. The U/S provides policy direction in the following areas: nonproliferation, including the missile and nuclear areas, as well as chemical, biological, and conventional weapons proliferation; arms control, including negotiation, ratification, verification and compliance, and implementation of agreements on strategic, non-conventional, and conventional forces; regional security and defense relations, involving policy regarding U.S. security commitments worldwide as well as on the use of U.S. military forces in unilateral or international peacekeeping roles; and arms transfers and security assistance programs and arms transfer policies.

By statute, the Assistant Secretary for Arms Control, Verification, and Compliance reports to the Under Secretary for Arms Control and International Security.
According to the Office of the Historian of the U.S. Department of State, the Under Secretary first received the permanent title "Senior Adviser to the President and the Secretary of State for Arms Control, Nonproliferation and Disarmament" when the Clinton administration decided to merge the Arms Control and Disarmament Agency and the United States Information Agency into the State Department, as well as realigning the United States Agency for International Development with it.
