RATIFIED

IN FORCE

15 March 2022

 

Status

Guinea-Bissau has signed and ratified the Treaty on the Prohibition of Nuclear Weapons (TPNW), and has been legally bound by it since 15 March 2022.

 

Signature and ratification

João Ribeiro Butiam Có, the then-minister of foreign affairs of Guinea-Bissau, signed the TPNW at a high-level ceremony in New York on 26 September 2018.

The National People’s Assembly of Guinea-Bissau approved ratification of the TPNW on 8 June 2021, and the instrument of ratification was deposited with the UN secretary-general on 15 December 2021.

On the occasion of the ratification, the minister of foreign affairs of Guinea-Bissau, Suzi Barbosa, said: “The ratification of the [TPNW] constitutes the last and important step towards the unequivocal affirmation of Guinea-Bissau’s commitment to a world free of nuclear weapons.”

Guinea-Bissau was the 58th state to ratify or accede to the TPNW.

Implementation

Per Article 12, Guinea-Bissau has promoted universal adherence to the TPNW, including by co-sponsoring and consistently voting in favour of an annual UN General Assembly resolution since 2018 that calls upon all states to sign, ratify, or accede to the treaty “at the earliest possible date”.

 

TPNW negotiations

While Guinea-Bissau did not formally participate in the negotiation of the TPNW at the United Nations in New York in 2017, it was among 122 states that voted in favour of its adoption.

In 2016, Guinea-Bissau co-sponsored the UN General Assembly resolution that established the formal mandate for states to commence negotiations on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

 

Before the negotiations

Guinea-Bissau was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the TPNW negotiations.
