Universalisation

São Tomé and Príncipe has promoted universal adherence to the treaty, including by 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”.

 

Treaty negotiations

São Tomé and Príncipe participated in the negotiation of the treaty at the United Nations in New York in 2017 and was among 122 states that voted in favour of its adoption.

In 2016, São Tomé and Príncipe was absent for the vote on 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

São Tomé and Príncipe 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 negotiations.
