the majority of States, almost all of which are non-nuclear-weapon States, are anxious to see a concrete result emerging from any negotiation to ban nuclear testing comprehensively.

A non-proliferation system can be respected only if it is based upon the conviction of States that their interests are better safeguarded within the system rather than outside it. I believe that the Conference could, if it so CD/PV.554 29 (Mr, Loeis.
