U.S. Department of State - Great Seal

U.S. Department of State

Diplomacy in Action

Office of Multilateral Nuclear and Security Affairs (ISN/MNSA)


This office has the lead role on a variety of multilateral nonproliferation and disarmament issues, including: the Treaty on the Non-Proliferation of Nuclear Weapons; safeguards, nuclear security, and technical cooperation programs under the International Atomic Energy Agency; U.S. bilateral safeguards and sister laboratory arrangements; nuclear-weapon-free-zone treaties and protocols; security assurances; and G7 and EU (CONOP and CODUN) nonproliferation and disarmament dialogues. This office also plays a supporting role for nonproliferation-related issues such as the safeguards aspects of fissile material cutoff and nuclear testing.

In formulating and directing U.S. policies in the areas described above, MNSA provides day-to-day policy guidance to U.S. missions to international organizations and coordinates closely with other ISN or T bureau offices having substantive expertise in these areas. MNSA also coordinates closely with White House offices and other U.S. agencies, including the Departments of Commerce, Defense, and Energy; the Nuclear Regulatory Commission; the Intelligence Community; and U.S. diplomatic missions in New York (USUN), Geneva (USDEL/CD) and Vienna (UNVIE). MNSA also advances policies in these areas with the Congress, the American public, and foreign audiences, in coordination with the ISN office of Strategic Communications and Outreach and the Bureaus of International Information Programs, Legislative Affairs, and Public Affairs.

Officers serve on U.S. delegations to meetings of the IAEA’s Board of Governors and General Conference, NPT Parties, the UNGA First Committee, the G-7 Nonproliferation Directors Group, and U.S.-EU bilateral consultations on nonproliferation. The office also conducts meetings with foreign governments, the United Nations and other international organizations.

Working closely with other State Department offices and our interagency partners, MNSA provides overall policy coordination concerning nuclear safeguards, security, and technical cooperation programs under the International Atomic Energy Agency. Among its other functions regarding the IAEA, MNSA oversees the U.S. contribution to the IAEA Peaceful Uses Initiative as well as provides policy support for U.S. bilateral safeguards.

MNSA leads interagency efforts to develop and carry out U.S. policies that support the establishment and implementation of Nuclear-Weapon-Free Zone treaties. Well-crafted NWFZs that meet certain criteria strengthen the NPT and the global nuclear nonproliferation regime, thus supporting U.S. foreign policy goals. MNSA coordinates U.S. policy on NWFZs and works to develop common approaches to the various NWFZs among the five nuclear weapons states.

The G-7 Nonproliferation Directors Group provides a forum where G-7 countries, at the Director-General level, consult on nonproliferation and arms control issues of urgent concern to narrow differences and coordinate on common approaches. One of the group’s top priorities is preventing the proliferation of weapons of mass destruction and their means of delivery; as such proliferation is a major threat to international peace and security.
