Latest developments

In the margins of the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Namibia chaired an African Group meeting to promote universalisation of the TPNW.2

In the First Committee of the UN General Assembly in October 2022, Namibia said that it is ‘encouraged by the entry into force of the TPNW and the progress in its implementation’. ‘The TPNW remains a major step towards a world free of nuclear weapons and, if we are genuine in our pursuit towards disarmament, we have a collective responsibility to ensure its universalisation,’ it said.3

In November 2022, in accordance with its Article 12 obligation to promote universal adherence to the TPNW, Namibia recommended that Brazil ratify the TPNW as part of the UN Human Rights Council’s Universal Periodic Review.4


  • Namibia should continue to encourage other states to adhere to the TPNW.

  • Namibia should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
