Nuclear-weapon-free state

Has not yet joined the TPNW


Ukraine has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons. It did not participate in the negotiation of the treaty at the United Nations in New York in 2017 and thus did not vote on its adoption. 


National position

Ukraine has abstained from voting on an annual UN General Assembly resolution that welcomes the adoption of the treaty and calls upon all states to sign, ratify, or accede to it “at the earliest possible date”.


Treaty negotiations

On the opening day of the TPNW negotiating conference in 2017, Ukraine joined the United States and several other states in protesting the treaty-making process.

In 2016, Ukraine was absent for the vote on the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.


Other information

Upon the break-up of the Soviet Union in 1991, Ukraine inherited several thousand Soviet nuclear warheads, which it subsequently transferred to Russia.
