Background

The 11th Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons took place in New York from 27 April to 22 May. It involved the states parties to the treaty, which met to review the operation of the nuclear non-proliferation regime and related issues. Do Hung Viet, Vietnam’s permanent representative to the United Nations, was nominated to serve as president of the conference.

The conference occurred in the context of periodic treaty review meetings, which are convened to assess implementation of the Nuclear Non-Proliferation Treaty and to consider questions of arms control, disarmament, and the peaceful uses of nuclear energy. It had immediate significance because it brought together participating states to discuss core obligations under the treaty and differences over nuclear disarmament and non-proliferation policy. Russian Deputy Foreign Minister Sergei Ryabkov met with Do Hung Viet ahead of the conference to discuss arms control, disarmament, and Iran’s nuclear program, indicating the range of issues that surrounded the meeting.

The conference formed part of the treaty’s continuing review process, which had been used to sustain multilateral dialogue on nuclear weapons, safeguards, and international security. Its proceedings and outcomes carried implications for subsequent discussions among treaty parties on compliance, consensus-building, and the broader nuclear order. The nomination of a president before the meeting also reflected the routine preparatory diplomacy that shaped the review conference agenda and leadership.
