In 1996, during a debate in the First Committee of the UN General Assembly, Sri Lanka stated:
While Sri Lanka calls upon the States that are still outside the Treaty to enter the NPT [Nuclear Non-Proliferation Treaty] fold, the States parties also have a responsibility to examine ways and means of attracting these remaining States to the Treaty. One of the most important objectives of Decision 2 was nuclear disarmament. In this regard it is important to recall the fact that the nuclear-weapon States reaffirmed their commitment made in 1968 to pursue in good faith negotiations on effective measures relating to nuclear disarmament. The time has now come for these States to translate their words into deeds.

In 1996, during a debate in the First Committee of the UN General Assembly, Sri Lanka stated:
Sri Lanka firmly believes that while the nuclear-weapon States are engaged in a phased approach to reducing their nuclear arsenals, the international community as a whole has the responsibility of swiftly engaging in multilateral negotiations towards eliminating the existing nuclear weapons and ensuring that no country will ever be permitted to manufacture, stockpile or use such weapons in the future. Nuclear weapons threaten the security of all, including the possessors of such weapons. Furthermore, they threaten the existence of mankind and of everything else in this fragile environment. Hence, Sri Lanka does not agree with the view expressed by some speakers in this forum that negotiations for the reduction or, for that matter, the elimination of nuclear weapons should be undertaken by the nuclear-weapon States among themselves.
