RATIFIED

IN FORCE

Status

Sudan has signed but not yet ratified the Treaty on the Prohibition of Nuclear Weapons (TPNW).

Signature

Omer Mohamed Ahmed Siddig, the then-permanent representative of Sudan to the United Nations, signed the TPNW on 22 July 2020.

Later that year, Sudan said that it “is currently undertaking its internal legal and administrative processes to ratify the treaty” and urged other states also to become parties.

National position

Sudan 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”.

In 2023, it said that the TPNW had “provided some optimism for progress in the field of nuclear disarmament”, adding that it considers the TPNW to be “complementary to the [Non-Proliferation Treaty of 1968], addressing the deep concern about the humanitarian consequences of any use of nuclear weapons”.

TPNW negotiations

Sudan participated in the negotiation of the TPNW at the United Nations in New York in 2017 and was among 122 states that voted in favour of its adoption.

In 2016, Sudan abstained from voting 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

Sudan 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.
