Thirty-fifth Session of the Organization of American States adopts resolution in support of the Comprehensive
Nuclear-Test-Ban Treaty
Vienna, Austria, 23 June 2005: The Organization of American States (OAS) General Assembly has adopted a resolution in
support of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) at its thirty-fifth Session. The resolution, entitled
"Inter-American support for the CTBT" was adopted at the fourth plenary session, held on 7 June 2005 in Florida, United
States of America. It is the sixth such resolution to have been adopted by the OAS General Assembly since 2000.
The OAS, which has 34 Member States, is the premier political forum for multilateral dialogue and action in the American
region. Major policies and directions are established by the General Assembly, which brings together the Hemisphere’s
foreign ministers once a year. The OAS plays a central role in working towards many of the goals shared by the countries
of North, Central and South America and the Caribbean, including the promotion of peace and security.
The resolution urges all States of the Hemisphere, to implement the “Measures to Promote the Entry into Force of the
Comprehensive Nuclear-Test-Ban Treaty (CTBT)” adopted at the Conference on Facilitating the Entry into Force of the
CTBT, which took place in Vienna, September 2003. It urges all States of the Hemisphere to attend and fully participate
in the next Conference on Facilitating the Entry into Force of the CTBT, which will take place in New York, United
States of America, from 21 to 23 September 2005.
The resolution also urges those States of the Hemisphere that have not yet done so, in particular States whose signature
and ratification are required for the Treaty to enter into force, to sign and ratify so that the Treaty may enter into
force as soon as possible. In addition, it urges States to refrain from contravening the spirit of the obligations of
the Treaty and to maintain in particular the moratorium on all nuclear testing.
The Comprehensive Nuclear-Test-Ban Treaty bans all nuclear weapon test explosions in any environment. To date the Treaty
has been signed by 175 States and ratified by 121 States. Drafted at the Conference on Disarmament in Geneva, and opened
for signature on 24 September 1996, the Treaty must be ratified by 44 named States before it can enter into force.
