ABSTRACT
Mexico played a decisive role in laying the groundwork that led to the historic adoption of the Treaty on the Prohibition of Nuclear Weapons (TPNW), and every state in Latin America participated in the negotiations and voted in favour of adopting the treaty. It was Honduras that finally triggered the ratification process when it deposited its instrument of ratification on 24 October 2020. The strong Latin American support for the TPNW was a natural step, entirely consistent with earlier, treaty-based commitments to renounce nuclear weapons, in particular the 1967 Treaty of Tlatelolco, a compelling testament to the longstanding regional commitment to nuclear abolition.
