Latest developments

In First Committee of the 2020 UN General Assembly, San Marino remarked: 'This year we commemorate the 75th anniversary of the first use of nuclear weapons in warfare in Hiroshima and Nagasaki. The touching testimonies of the survivors are a constant reminder that we need to urgently commit to a world free of nuclear weapons. The Republic of San Marino has therefore decided to sign and ratify the TPNW, an instrument that can give a critical contribution to peace and security. We encourage other Countries to sign and ratify this treaty. San Marino stands for a world free of weapons of mass destruction, free of nuclear, chemical and bacteriological weapons. We are convinced that peace and security can be reached through cooperation, dialogue, transparency and trust, investing more in education, development and cooperation rather than in armaments and wars.' See:


  • San Marino should continue to encourage other states to adhere to the TPNW.
  • San Marino should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
  • San Marino should conclude and bring into force an Additional Protocol (AP) with the IAEA.
