South Africa
Practice Relating to Nuclear Weapons
In 1996, during a debate in the First Committee of the UN General Assembly, South Africa stated:
Recent years have seen many accomplishments in the area of disarmament. On the multilateral and global level, these have included … the strengthening of the network of nuclear-weapon-free zones with the recent conclusion of the Pelindaba Treaty and the Bangkok Treaty, which have had the effect of extending nuclear-weapon-free zones to cover the entire southern hemisphere. These initiatives are a clear demonstration of the continued commitment of non-nuclear-weapon States to the goal of ridding the world of nuclear weapons.
