NPT - CTBT Timeline
- 1 January 1967: cut-off date defined by Art IX NPT: "For the purposes of this Treaty, a nuclear-weapon State is one which has manufactured and exploded a nuclear weapon or other nuclear explosive device prior to 1 January 1967."
- 1 July 1968: NPT opens for signature. Preambular paragraph 11: "Recalling the determination expressed by the Parties to the 1963 Treaty banning nuclear weapons tests in the atmosphere, in outer space and under water in its Preamble to seek to achieve the discontinuance of all test explosions of nuclear weapons for all time and to continue negotiations to this end,"
- 1990: The NPT Review Conference fails to agree on a final declaration as the result of disagreement between the nuclear weapon States and the Non-Aligned Movement over the lack of progress, including by in concluding a CTBT.
- 1995: Indefinite extension of the NPT at the Review Conference. The completion of the CTBT, which was already being negotiated at the Conference on Disarmament in Geneva, played a key role.
-2000: The CTBT figures as the first of the "13 practical steps" adopted by the 2000 Review Conference: "The importance and urgency of signatures and ratifications, without delay and without conditions and in accordance with constitutional processes, to achieve the early entry into force of the Comprehensive Nuclear-Test-Ban Treaty."
- 2005: Again failure to agree on a joint document, in part due to the refusal of one State to acknowledge the CTBT's importance as highlighted at the 2000 Review Conference.
- 2010: The Final Document is adopted by consensus that "reaffirms the essential role of the Comprehensive Nuclear-Test-Ban Treaty within the nuclear disarmament and non-proliferation regime and that by achieving the cessation of all nuclear weapon test explosions and all other nuclear explosions, by constraining the development and qualitative improvement of nuclear weapons and ending the development of advanced new types of nuclear weapons, the Treaty combats both horizontal and vertical proliferation."
In addition, the conference adopts a Plan of Action (CTBT) whose points 10 to 14 feature concrete actions to promote the CTBT's entry into force.
An Arabic proverb says "You need a brother, without one you're a person rushing to battle without a weapon." It is my conviction that the NPT and CTBT are brothers that only stand strong together.Ambassador Taous Feroukhi, President of the 2015 NPT Review Conference
