Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Cuba described the TPNW as complementary to the NPT and hailed its entry into force in 2021 as ‘an undeniable milestone to advance towards nuclear disarmament’. It urged all states to ratify the Treaty ‘for its prompt universalisation’.2

During the high-level segment of the UN General Assembly in September 2022, Rodriguez Parilla said that Cuba champions the universalisation of the TPNW. ‘Nothing justifies the fact that humankind continues to remain threatened by the existence of around 13,000 nuclear weapons,’ he said.3

In the First Committee of the UN General Assembly in October 2022, Cuba said that the total elimination of nuclear weapons ‘​​is a matter of survival for humanity’ and ‘must continue to be the top priority in the field of disarmament’. Consistent with this view, ‘Cuba will continue to promote the universalisation of the TPNW.’4


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

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