The links between NPT & CTBT

From 27 April to 22 May 2015, the 190 State Parties to the Nuclear Non-Proliferation Treaty (NPT) are gathering at the United Nations headquarters in New York, United States, for the NPT's ninth Review Conference. The NPT and the ban on nuclear testing are closely connected. The NPT's preamble enshrines the aim to end all nuclear tests "for all time". The Comprehensive Nuclear-Test-Ban Treaty (CTBT), which was being negotiated in the mid-1990s, played a key role in the indefinite extension of the NPT at the 1995 Review Conference, and figured as the first of the 13 steps adopted by the 2000 Review Conference.


"Mere words of support without real action will not suffice. Bringing the CTBT into force is the responsibility of all NPT States Parties."

See Executive Secretary Lassina Zerbo's statement (PDF) to the NPT Review Conference, held on 29 April.

Following the end of the NPT Review Conference, GEM Member Sergio Duarte, who presided the 2005 Review Conference, argues why the conference, in spite of not agreeing on a Final Document, can be the starting point for a new and ambitious nuclear disarmament initiative.
