Latest developments

In a closing statement to the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Cabo Verde and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.1

Cabo Verde was one of the co-sponsors for the 2022 UN General Assembly resolution on the TPNW, which called upon ‘all States that have not yet done so to sign, ratify, accept, approve or accede to the Treaty at the earliest possible date.'2


  • Cabo Verde should continue to encourage other states to adhere to the TPNW.

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