Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Tuvalu, together with 64 other TPNW supporters, urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.1

The Pacific Small Island Developing States, of which Tuvalu is a member, delivered a joint statement at the NPT Review Conference which said: “We are gravely concerned about the serious shortfalls in the implementation of Article VI of the NPT although the nuclear weapon states have spent billions of dollars on modernizing and maintaining their nuclear arsenals. This amount could have been better spent on helping victims of past use and testing of nuclear weapons, fighting the global pandemic of Covid-19 and on the sustainable development goals.” The joint statement also said that ‘Despite the unfortunate recent behavior, following the invasion of Ukraine, and hinting at their possible use, there is hope’, and noted the entry into force of the TPNW and the convening of the Treaty's First Meeting of States Parties (1MSP).2


  • Tuvalu should continue to encourage other states to adhere to the TPNW.

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

  • Tuvalu should conclude and bring into force an Additional Protocol with the IAEA.

  • Tuvalu should adhere to the Biological Weapons Convention (BWC).
