In 1996, during a debate in the First Committee of the UN General Assembly, Pakistan stated:
Pakistan is aware of the need for restraint and responsibility in the production and trade of all armaments, conventional and non-conventional. We are prepared to work for internationally negotiated regimes in sensitive areas. … The post-cold-war period has created a historic window of opportunity to realize the goal of ridding the world of nuclear weapons. Nuclear Powers are no longer locked in a strategic contest. They do not need nuclear weapons against each other and they certainly do not need them against non-nuclear States. If this opportunity to realize nuclear disarmament is not seized, it may not return. Great Power rivalries may revive. A multipolar nuclear world could multiply the dangers of deliberate or accidental use of nuclear weapons.

In 1996, during a debate in the First Committee of the UN General Assembly, the representative of Pakistan stated:
In the informal discussions that we have held on the subject of nuclear disarmament, my delegation has noted with satisfaction that the nuclear-weapon States have confirmed that they too are committed to the ultimate goal of the elimination of nuclear weapons. That being so, we believe that agreement can be achieved on a course of action to promote negotiations on nuclear disarmament, especially in the Conference on Disarmament.
