SIGNED

RATIFIED

IN FORCE

Status

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

National position

It welcomed the TPNW’s adoption in 2017, describing it as “an important step towards freeing our world from nuclear weapons”, as well as its entry into force in 2021.

Yemen has promoted universal adherence to the TPNW, 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”.

Meetings of states parties

Yemen observed the first meeting of states parties to the TPNW in 2022, describing it as a step towards the goal of a nuclear-weapon-free world.

It also observed the second meeting of states parties in 2023 and the third meeting in 2025.

TPNW negotiations

Yemen 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, Yemen voted in favour of the UN General Assembly resolution that established the mandate for states to commence negotiations on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

Before the negotiations

Yemen 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.
