Latest developments

In the First Committee of the 2021 UN General Assembly, Austria said: 'The clear majority of the world has rejected the dangerous illusion of security through nuclear deterrence by adopting the TPNW. Following the Treaty’s entry into force this year 2021, we look forward to the First Meeting of States Parties in Vienna [...], where we aim to strengthen and foster engagement with the TPNW’s important humanitarian and security arguments. We invite all States to sign and ratify the Treaty and join the meeting as States parties or observers.'1

Also in the First Committe, Austria said: 'The entry into force of the TPNW constitutes an urgently needed strengthening of the international nuclear disarmament and non-proliferation regime – a regime that is built through mutually reinforcing instruments. Moreover, the TPNW strengthens the taboo against nuclear weapons, irrespective of who possesses them.'2


  • Austria should continue to encourage other states to adhere to the TPNW.
  • Austria should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
