text: with no reservations whatsoever. Otherwise, the significance would be lost. To pledge not to use nuclear weapons against non-nuclear States and nuclear-freeze zones has long been demanded by the non-nuclear States. As the overwhelming -majority of non-nuclear States have voluntarily given up their nuclear options, it is highly justified and reasonable for them to demand safety assurances from the nuclear States. Such assurances must also be unconditional, and anything short of that would undermine their significance. As to the conclusion of an international convention on the prohibition of the use of nuclear weapons, it would just be the natural and logical outcome when all the nuclear States have undertaken unconditionally not to be the first to use nuclear weapons and not to use nuclear weapons against non-nuclear states and nuclear-free zones. Today, both the American and Soviet leaders have accepted that a nuclear war could not be won and should never be fought. Such being the case, it should not be difficult for them to undertake the above-mentioned commitment. secondly, we propose that in order to avert the possible escalation of a conventional war into a nuclear war in areas with a high concentration of nuclear AW/gmr A/C.l/40/PV.S 49-50 (Mr. Qian Jiadong, China) and. conventional weapons, the two military blocs, the North Atlantic Treaty organization (NATO) and the Warsaw Treaty organization should reach an agreement as early as possible on the drastic reduction of their conventional armaments. We have long held that in the nuclear era, there is no insurmountable barrier between a nuclear war and a conventional war. Efforts for nuclear disarmament should therefore be combined with those for conventional disarmament. This will not only be conducive to smooth progress in nuclear disarmament, but also to the lessening of the danger of a war, including a nuclear war. This interrelationship
