Liechtenstein Liechtenstein


States with nuclear-free security strategies

Liechtenstein has signed the TPNW and is in compliance with all of the prohibitions in Article 1, but has not yet ratified the Treaty.

Latest developments and background

Preparatory work for Liechtenstein's ratification of the TPNW is ongoing. Speaking in the UN General Assembly on 26 September 2019, Liechtenstein said: “Along with many other states, Liechtenstein sees important potential in the TPNW to restore the origina balance enshrined in the NPT. [...] Most importantly, it draws a legal line against all attempts to justify the use of nuclear weapons. The horrendous and indiscriminate suffering these weapons infallibly inflict on civilians leaves no room for such justification. In a time of eroding international norms, the TPNW is a sole beacon of hope and a lesson for multilateralism in a world increasingly suffering from unsustainable big power politics.” (


  • Liechtenstein should urgently ratify the TPNW, and encourage other states to adhere to the Treaty.
