Practice Relating to Nuclear Weapons
In 1996, during a debate in the First Committee of the UN General Assembly, Nigeria stated:
For our part, as the Minister for Foreign Affairs of Nigeria indicated in plenary meeting earlier this month, we hope to sign the Treaty in due course. All this is remarkable. It reflects the conviction of the international community that the Treaty holds out the distinct hope of contributing to our collective commitment to a safer, more secure and nuclear-weapon-free world. The Treaty has imposed on the nuclear-weapon States in particular the unique responsibility of joining with the rest of humankind in working for a complete end to all forms of nuclear-weapons testing.
