Latest developments

At the 2021 UN General Assembly's High-level plenary for the International Day for the Total Elimination of Nuclear Weapons, Nigeria's President Muhammudu Buuhari congratulated member states on the entry into force of the TPNW. He said that Nigeria was 'honored to join other countries in the core group to co-sponsor the resolution that led to the adoption of the Treaty,' that it calls upon 'other member states who have yet to sign and ratify the treaty to follow suit.' Finally, he said that Nigeria "reiterate[s] the need for all the prohibitions identified in the new treaty to be observed by all member states of the United Nations.'1

In the First Committee of the 2021 UN General Assembly, Nigeria said that the TPNW will 'contribute to furthering the global objective of the total elimination of nuclear weapons' and that it looked forward to the First Meeting of States Parties in 2022.2


  • Nigeria should continue to encourage other states to adhere to the TPNW.
  • Nigeria should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
