Complementarity of the TPNW with other nuclear weapons treaties

The TPNW builds upon, contributes to and complements a rich and diverse disarmament and non-proliferation architecture. In the Vienna Action Plan states parties agreed therefore to four actions, Actions 35-38 to “highlight and underscore these complementarities with specific disarmament instruments, particularly the Non-Proliferation Treaty.” States committed to “emphasize the complementarity of the Treaty with the existing disarmament and non-proliferation regime at appropriate opportunities, including preparatory meetings and review conferences of the Non-Proliferation Treaty, and with relevant multilateral nuclear disarmament-related initiatives and groupings,” “To cooperate with other international bodies, such as the International Atomic Energy Agency and the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization, in order to enhance cooperation, including in the areas of nuclear safeguards and verification,” and to “to continue to work together on outreach projects in order to raise awareness.”

At 2MSP, the informal facilitators, Ireland and Thailand, presented the report on their work to further explore and articulate the possible areas of tangible cooperation between the TPNW and the NPT, and other relevant nuclear disarmament and non-proliferation instruments. The mandate of the informal facilitators was renewed (Decision 1) for the next intersessional period.
