Zambia
Practice Relating to Nuclear Weapons
In 1996, during a debate in the First Committee of the UN General Assembly, the representative of Zambia stated:
My delegation wishes to reaffirm the view commonly held by the members of the Movement of Non-Aligned Countries that a phased programme, with agreed timeframes, to achieve a nuclear-weapon-free world by the year 2020 is the only meaningful way of conclusively tackling the issue of nuclear disarmament. It underscores the Movement’s unremitting drive for early attainment of a nuclear-weapon-free world.
