Sudan
Practice Relating to Nuclear Weapons
In 1996, during a debate in the First Committee of the UN General Assembly, the Sudan stated:
The International Court of Justice advisory opinion issued in July of this year on the legality of the threat or use of nuclear weapons was viewed with respect and appreciation by all States. It stressed unequivocally the need to pursue endeavours to achieve nuclear disarmament under effective international control. That advisory opinion revived hope in nuclear disarmament.
