                                                3 December 1986
                                                94th plenary meeting
          Urgent need for a comprehensive nuclear-test-ban treaty
     The General Assembly,
     Convinced that a nuclear war cannot be won and must never be fought,
     Convinced of the consequent urgent need for an end to the nuclear-arms
race and the immediate and verifiable reduction and ultimate elimination of
nuclear weapons,
     Convinced, therefore, that an end to all 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 further nuclear
proliferation and to contribute, along with other concurrent efforts to limit
and reduce nuclear arms, to the eventual elimination of nuclear weapons,
     Noting that the Union of Soviet Socialist Republics and the United States
of America are engaged in nuclear and space talks and in consultations on the
entire scope of issues relating to nuclear testing, and expressing the hope
that those talks and consultations will lead to both early and concrete
     Noting also recent initiatives, including the proposals by the leaders of
the six countries associated with the five-continent initiative, to promote an
end to nuclear testing,
     Convinced that the most effective way to achieve the discontinuance of
all nuclear tests in all environments for all time is through the conclusion
of a verifiable, comprehensive nuclear-test-ban treaty open to and capable of
attracting the adherence of all States,
     Reaffirming the responsibilities of the Conference on Disarmament in the
negotiation of a comprehensive nuclear-test-ban treaty,
     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 fundamental importance;
     2.   Urges, therefore, that the following actions be taken in order that
a comprehensive nuclear-test-ban treaty may be concluded at an early date:
     (a)  The Conference on Disarmament should commence practical work on a
nuclear-test-ban treaty at the beginning of its 1987 session;
     (b)  States members of the Conference on Disarmament, in particular the
nuclear-weapon States, and all other States, should co-operate with the
Conference on Disarmament in order to facilitate and promote such work;
     (c)  The nuclear-weapon States, especially those which possess the most
important nuclear arsenals, should agree to appropriate verifiable, interim
measures with a view to realizing a comprehensive nuclear-test-ban treaty;
     (d)  Those nuclear-weapon States that have not yet done so should adhere
to the Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space
and under Water;
     3.   Also urges the Conference on Disarmament:
     (a)  To take immediate steps for the establishment, with the widest
possible participation, of an international seismic monitoring network with a
view to the further development of its potential to monitor and verify
compliance with a comprehensive nuclear-test-ban treaty;
     (b)  In this context, to take into account the progress achieved by the
Ad Hoc Group of Scientific Experts to Consider International Co-operative
Measures to Detect and Identify Seismic Events, including the exchange of
wave-form data, and other relevant initiatives by individual States and groups
of States;
     (c)  To initiate detailed investigation of other measures to monitor and
verify compliance with such a treaty, including an international network to
monitor atmospheric radioactivity;
     4.   Calls upon the Conference on Disarmament to report on progress to
the General Assembly at its forty-second session;
     5.   Decides to include in the provisional agenda of its forty-second
session the item entitled "Urgent need for a comprehensive nuclear-test-ban
