                                                   65th plenary meeting

           Comprehensive nuclear-test-ban treaty
 
     The General Assembly,
 
     Recalling previous resolutions which identify the complete cessation of
nuclear-weapon tests and a comprehensive test ban as one of the basic
objectives in the field of disarmament,
 
     Convinced that a nuclear war cannot be won and must never be fought,
 
     Welcoming the improved relationship between the Union of Soviet Socialist
Republics and the United States of America and their consequent announcements
of significant measures, including unilateral steps, which could signal the
reversal of the nuclear arms race,
 
     Welcoming also the Treaty between the United States of America and the
Union of Soviet Socialist Republics on the Reduction and Limitation of
Strategic Offensive Arms, signed on 31 July 1991, and expressing the hope that
it will be followed by agreement at an early date on further cuts in strategic
nuclear arsenals,
 
     Recognizing the ratification of the Treaty between the United States of
America and the Union of Soviet Socialist Republics on the Limitation of
Underground Nuclear Weapon Tests, signed on 3 July 1974, and the Treaty
between the United States of America and the Union of Soviet Socialist
Republics on Underground Nuclear Explosions for Peaceful Purposes, signed on
28 May  1976, together with their protocols,
 
     Noting the decline, in comparison with previous years, in the number of
nuclear tests conducted in 1990,
 
     Convinced that an end to nuclear testing by all States in all
environments for all time is an essential step in order to prevent the
qualitative improvement and development of nuclear weapons and their further
proliferation and to contribute, along with other concurrent efforts to reduce
nuclear arms, to the eventual elimination of nuclear weapons,
 
     Noting also concerns expressed about the environmental and health risks
associated with underground nuclear testing,
 
     Convinced also that the most effective way to achieve an end to nuclear
testing is through the conclusion, at an early date, of a verifiable,
comprehensive nuclear-test-ban treaty that will attract the adherence of all
States,
 
     Taking into account the undertakings by the original parties to the 1963
Treaty Banning Nuclear Weapons Tests in the Atmosphere, in Outer Space and
under Water4 to seek to achieve the early discontinuance of all test
explosions of nuclear weapons for all time and also noting the reiteration of
this commitment in the 1968 Treaty on the Non-Proliferation of Nuclear
Weapons, 
 
     Noting with satisfaction the work being undertaken within the Conference
on Disarmament by the Ad Hoc Group of Scientific Experts to Consider
International Cooperative Measures to Detect and Identify Seismic Events, and
in this context welcoming the second technical test concerning the global
exchange and analysis of seismic data,
 
     Recalling that the Amendment Conference of the States Parties to the
Treaty Banning Nuclear Weapons Tests in the Atmosphere, in Outer Space and
under Water was held in New York from 7 to 18 January 1991,
 
     1.   Reaffirms its conviction that a treaty to achieve the prohibition of
all nuclear-test explosions by all States in all environments for all time is
a matter of priority which would constitute an essential step in order to
prevent the qualitative improvement and development of nuclear weapons and
their further proliferation, and which would contribute to the process of
nuclear disarmament;
 
     2.   Urges, therefore, all States to seek to achieve the early
discontinuance of all nuclear-test explosions for all time;
 
     3.   Reaffirms the particular responsibilities of the Conference on
Disarmament in the negotiation of a comprehensive nuclear-test-ban treaty, and
in this context urges the re-establishment of the Ad Hoc Committee on a
Nuclear Test Ban in 1992 with an appropriate mandate;
 
     4.   Requests the Conference on Disarmament, in this context, to
intensify its substantive work on specific and interrelated test-ban issues,
including structure and scope and verification and compliance, taking also
into account all relevant proposals and future initiatives;
 
     5.   Urges the Conference on Disarmament:
 
     (a)  To take into account the progress achieved by the Ad Hoc Group of
Scientific Experts to Consider International Cooperative Measures to Detect
and Identify Seismic Events, including the experience gained from the
technical test concerning the global exchange and analysis of seismic data,
and other relevant initiatives;
 
     (b)  To continue efforts to establish, with the widest possible
participation, an international seismic monitoring network with a view to
developing further a system for the effective monitoring and verification of
compliance with a comprehensive nuclear-test-ban treaty;
 
     (c)  To investigate other measures to monitor and verify compliance with
such a treaty, including on-site inspections, satellite monitoring and an
international network to monitor atmospheric radioactivity;
 
     6.   Urges:
 
     (a)  The nuclear-weapon States to agree promptly to appropriate
verifiable and militarily significant interim measures, with a view to
concluding a comprehensive nuclear-test-ban treaty;
 
     (b)  Those nuclear-weapon States which have not yet done so to adhere to
the Treaty Banning Nuclear Weapons Tests in the Atmosphere, in Outer Space and
under Water;
 
     7.   Calls upon the Conference on Disarmament to report to the General
Assembly at its forty-seventh session on progress made;
 
     8.   Decides to include in the provisional agenda of its forty-seventh
session an item entitled "Comprehensive nuclear-test-ban treaty".
