Latest developments

Attending as an observer the First Meeting of States Parties to the TPNW (1MSP) in Vienna in June 2022, the Dominican Republic said: ‘The adoption in July 2017 of the [TPNW] and its entry into force in January 2021 are historic achievements … They represent the culmination of decades of efforts aimed at eliminating these weapons of mass destruction.’1

During the high-level segment of the UN General Assembly in September 2022, the Minister of Foreign Affairs, Roberto Álvarez Gil, said that the Dominican Republic ‘supports the total elimination of nuclear weapons’, and that its ratification of the TPNW is proof of this. He said that ‘humanity requires results that favour peace and avoid new conflicts, especially those that imply a danger to the very existence of the planet’.2

Marking the International Day for the Total Elimination of Nuclear Weapons on 26 September 2022, the Dominican Republic encouraged ‘states that have not yet done so to accede to the [TPNW] with a view to its universalisation’ and expressed its ‘deep gratitude to the organisations and delegations that work tirelessly towards this overall goal, including ICAN and the International Committee of the Red Cross’.3


  • The Dominican Republic should submit its declaration under Article 2 of the TPNW to the UN Secretary-General without further delay.

  • The Dominican Republic should continue to encourage other states to adhere to the TPNW.

  • The Dominican Republic should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
