Latest developments

Marking the International Day for the Total Elimination of Nuclear Weapons on 26 September 2022, the Minister of Foreign Affairs of Lesotho, Matšepo Ramakoae, welcomed the TPNW’s entry into force in January 2021 as ‘a significant milestone in the efforts towards promoting universalisation and full implementation of the TPNW’. She added that Lesotho ‘supports all efforts to enhance the institutional fabric of the TPNW’.2 In a closing statement to the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Lesotho and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.3

In the First Committee of the UN General Assembly in October 2022, Lesotho said that it is ‘strongly committed to the TPNW and will continue to support the principle of complete nuclear disarmament, as the utmost prerequisite for maintaining international peace and security’.4

Recommendations

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

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