Ministers Call Upon Remaining Nine Countries To Clear Way For Nuclear-Test-Ban Treaty
Today, on 24 September 2008, Foreign Ministers from about 40 countries gathered to reaffirm their commitment to promote
the entry into force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) at the highest political level. When in force,
the CTBT will ban all nuclear weapons testing on Earth.
The Foreign Ministers issued the following statement, calling upon the nine countries who still have to ratify before
the Treaty can enter into force to do so without delay. These countries are: China, Democratic People’s Republic of
Korea (DPRK), Egypt, India, Indonesia, Iran, Israel, Pakistan, and the United States.
The Ministers also urged all States to continue their moratoria on nuclear weapon tests, while stressing that such
voluntary suspension of nuclear weapon testing does not have the same permanent and legally binding effect as the entry
into force of the CTBT.
The main instrument for promoting the Treaty’s entry into force are conferences convened by Member States that take
place every two years, so-called Article XIV Conferences after the relevant Article of the Treaty. The last such
conference took place in Vienna in September 2007.
In the years between the Article XIV Conferences, Foreign Ministers of particularly dedicated CTBT Member States meet to
sustain and generate further political momentum for the entry into force of the Treaty. The Joint Ministerial Statements
adopted by the Ministers are open for endorsement by other countries.
Adherence to the CTBT is now almost universal. A total of 179 States have signed the CTBT, the latest being Iraq. To
enter into force, however, the Treaty must be signed and ratified by the 44 States listed in Annex 2 to the CTBT. These
States participated in the Treaty’s negotiations in 1996 and possessed nuclear power or research reactors at the time.
Thirty-five of these States have ratified, including the three nuclear weapon States: France, Russian Federation, and
the United Kingdom.
The CTBT bans all nuclear explosions. A verification regime is being built to monitor compliance with the Treaty. A
total of 337 facilities worldwide constituting the International Monitoring System are foreseen to monitor the oceans,
underground and atmosphere for any sign of a nuclear explosion.
Joint Ministerial Statement On The CTBT
September 24, 2008 New York
1. We, the Foreign Ministers who have issued this statement, reaffirm our strong support for the Comprehensive
Nuclear-Test-Ban Treaty (CTBT), which would rid the world of nuclear weapons test explosions and would contribute to
nuclear disarmament and non-proliferation.
2. In this year marking the 12th anniversary of the Treaty's opening for signature, we emphasize that the CTBT is a
major instrument in the field of nuclear disarmament and non-proliferation. The Treaty was an integral part of the 1995
agreements by the States parties to the Nuclear Non-Proliferation Treaty (NPT) allowing the indefinite extension of the
Treaty. The early entry into force of the CTBT was recognized at the 2000 Review Conference of the NPT as a practical
step to achieving NPT nuclear disarmament and non-proliferation objectives, and has also been reaffirmed as being of
central importance by the UN General Assembly.
3. We recall the Conference on Facilitating the Entry into Force of the Comprehensive Nuclear -Test-Ban Treaty, that
adopted in September 2007 a declaration by consensus outlining measures consistent with international law to encourage
further signature and ratification of the Treaty.
4. We affirm that the CTBT will make an important contribution by constraining the development and qualitative
improvement of nuclear weapons and ending the development of advanced new types of nuclear weapons, as well as
preventing the proliferation of nuclear weapons in all its aspects. The entry into force of the Treaty is vital to the
broader framework of multilateral disarmament and non-proliferation efforts. Progress on this issue would also
contribute to a positive outcome of the 2010 Review Conference of the NPT.
5. We welcome that the CTBT has achieved near universal adherence with signature by 179 States and ratification by 144
States as of today. Of the 44 States whose ratification is necessary for the entry into force of the Treaty, nine have
yet to do so. We welcome the four ratifications that have occurred since the entry into force conference last year, in
particular that of Colombia, one of the states whose ratification is necessary for the entry into force of the Treaty.
We call upon all States that have not yet done so to sign and ratify the Treaty without delay, in particular those whose
ratification is needed for its entry into force. We recognise the extensive range of bilateral and joint outreach
efforts by signatories and ratifiers to encourage and assist States which have not yet signed and ratified the Treaty.
We commit ourselves individually and together to make the Treaty a focus of attention at the highest political levels
and to take measures to facilitate the signature and ratification process. We support the efforts by the Preparatory
Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization to facilitate such process by providing legal and
technical information and advice.
6. We call upon all States to continue a moratorium on nuclear weapon test explosions or any other nuclear explosions.
Voluntary adherence to such a moratorium is a welcome step, but does not have the same permanent and legally binding
effect as the entry into force of the Treaty. We reaffirm our commitment to the Treaty's basic obligations and call on
all States to refrain from acts which would defeat the object and purpose of the Treaty pending its entry into force.
With respect to the nuclear test announced by the Democratic People’s Republic of Korea on 9 October 2006, bearing in
mind UNGA Res 61/104, we underline the need for a peaceful solution of the nuclear issues through successful
implementation of the Six Party Talks Joint Statement of September 2005 and we urge the DPRK to fulfil its commitments
therein and to fully comply with Security Council resolutions 1695 and 1718. We note that the verification regime
successfully detected the aforementioned event and believe that it highlighted the urgent need for the early entry into
force of the Treaty.
7. We welcome the progress made in building up all elements of the verification regime, which shall be capable of
verifying compliance with the Treaty at its entry into force. We will provide the support required to complete and
operate the verification regime in the most efficient and cost-effective way. We will also promote technical cooperation
to enhance verification capabilities under the CTBT.
8. In addition to its primary function, the CTBT International Monitoring System as part of the verification regime is
bringing scientific and civil benefits, including for tsunami warning systems and possibly other disaster alert systems,
through civil and scientific applications of waveform and radionuclide technologies and use of the data. We will
continue to seek ways to ensure that these benefits will be broadly shared by the international community in conformity
with the Treaty.
9. We appeal to all States to make maximum efforts towards achieving the early entry into force of the CTBT. On our part
we dedicate ourselves to realizing this goal.
