Liechtenstein
In December 2022, in response to an inquiry from the Nuclear Weapons Ban Monitor about the status of Liechtenstein’s ratification process for the TPNW, the foreign ministry referred to a letter that the Minister of Foreign Affairs, Dominique Hasler, sent to ICAN one year earlier, in which she wrote that ‘Liechtenstein forms a Customs Union with Switzerland and certain Swiss laws apply to Liechtenstein. Those laws include areas falling under the purview of the TPNW. Due to this circumstance we have to await the finalisation of the domestic processes in Switzerland before a ratification can take place. However, we will be monitoring the process and I can assure you that Liechtenstein will continue to strive for ratification in due time.’[1]

Latest developments
In the First Committee of the UN General Assembly in October 2023, Liechtenstein said that ‘it is crystal clear’ that nuclear weapons ‘will never make the world a safer place’. ‘This understanding is the animating force behind the Treaty on the Prohibition of Nuclear Weapons,’ it added, noting that the TPNW ‘strengthens the NPT framework in defining new and concrete perspectives for nuclear disarmament’.2
Liechtenstein observed the Second Meeting of States Parties to the TPNW (2MSP) in November and December 2023 but did not make a statement. It was one of the co-sponsors for the 2023 UN General Assembly resolution on the TPNW, which called upon ‘all States that have not yet done so to sign, ratify, accept, approve or accede to the Treaty at the earliest possible date’.3
