During the high-level segment of the UN General Assembly in September 2022, San Marino's Minister for Foreign Affairs and International Cooperation, Luca Beccari, urged all states committed to the goal of a nuclear-weapon-free world to join the TPNW. ‘Only by honouring and reinvigorating our multilateral agreements will we be able to put humanity on a new path towards a world free of nuclear weapons,’ he said.[1]

Latest developments

San Marino participated in the First Meeting of States Parties to the TPNW (1MSP) in June 2022, but did not make a statement.

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, San Marino said that nuclear weapons ‘do not bring security’ but rather their mere existence ‘results in a great risk for humanity’. It stressed that it is in ‘the interest of the very survival of humanity that nuclear weapons are never used again, under any circumstances’. It also welcomed the TPNW’s adoption and entry into force, as well as the Vienna Declaration and Action Plan adopted at the 1MSP, and said: ‘This Treaty represents a new step towards the implementation of Article VI of the NPT and towards our shared goal of a world without nuclear weapons.’2 In a closing statement to the NPT Review Conference, San Marino and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.3

In the First Committee of the UN General Assembly in October 2022, San Marino said that the TPNW’s entry into force represented ‘a historic milestone in our disarmament architecture’ and welcomed the increasing number of signatories and parties.4

San Marino was one of the co-sponsors for the 2022 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.’5


  • 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 with the IAEA.
