Nuclear-weapon-free state

Has signed the TPNW

Has ratified the TPNW

Laos has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.

Saleumxay Kommsith, the minister for foreign affairs of Laos, signed the treaty on 21 September 2017. He deposited the country’s instrument of ratification with the UN secretary-general on 26 September 2019.

Laos participated in the negotiation of the Treaty on the Prohibition of Nuclear Weapons at the United Nations in New York in 2017 and voted in favour of its adoption.

Laos has promoted universal adherence to the treaty, including by co-sponsoring a UN General Assembly resolution in 2019 that calls upon all states to sign, ratify, or accede to the treaty “at the earliest possible date”.

In its opening statement to the negotiating conference, Laos said that “this conference is timely and important, as we believe that it will help to pave the way toward a complete nuclear disarmament”.

In 2016, Laos voted in favour of 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”.

Prior to the adoption of the treaty in 2017, nuclear weapons were the only weapons of mass destruction not subject to a comprehensive, globally applicable treaty prohibition. Laos supported calls in the UN General Assembly fill this “legal gap”.

Laos is a state party to the 1995 Treaty of Bangkok, which established Southeast Asia as a nuclear-weapon-free zone.
