San Marino

Nuclear-weapon-free state

Has signed the TPNW

Has ratified the TPNW

San Marino has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.

Nicola Renzi, the minister for foreign and political affairs of San Marino, signed the treaty on 20 September 2017. He deposited the country’s instrument of ratification with the UN secretary-general on 26 September 2018

In an address to the United Nations following the signing ceremony in September 2017, Renzi described the treaty as “an important step to achieve the common goal of a world without nuclear weapons”.

San Marino participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.

San Marino has promoted universal adherence to the treaty, including by co-sponsoring a UN General Assembly resolution in 2019 that calls upon all states to sign, ratify, or accede to the treaty “at the earliest possible date”.

In 2016, San Marino was an additional co-sponsor of the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

San Marino was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the negotiations.
