Latest developments

Guinea-Bissau 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.'1

Marking the International Day for the Total Elimination of Nuclear Weapons on 26 September 2022, the African Group in the UN, of which Guinea-Bissau is a member, recalled the entry into force of the ‘landmark’ TPNW and reaffirmed its ‘full support’ for the declaration and action plan adopted at the 1MSP. The African Group, moreover, urged ‘all members of the international community, especially nuclear-weapon states and those under the so-called nuclear umbrella, to seize the opportunity to sign and ratify the Treaty at an early date and to pursue the goal of a nuclear-weapon-free world’.2

Recommendations

  • Guinea-Bissau should continue to encourage other states to adhere to the TPNW.

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