Latest developments
Yemen maintains policies and practices that are compatible with all of the prohibitions in Article 1 of the TPNW, and can therefore sign and ratify or accede to the Treaty without the need for a change in conduct.
At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Yemen welcomed the TPNW’s adoption in 2017 and its entry into force in 2021, and described the convening of the 1MSP as a step towards the goal of a nuclear-weapon-free world.1
Recommendations
-
Yemen should urgently adhere to the TPNW.
-
Yemen should conclude and bring into force an Additional Protocol with the IAEA, and upgrade to a Modified Small Quantities Protocol.
-
Yemen should also ratify the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
