Together with New Zealand, Mexico was also appointed by the 1MSP as co-chair of an informal working group responsible for promoting implementation of Article 4 of the TPNW, in particular with respect to the future designation of a competent international authority or authorities to oversee such work.
At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Mexico described the TPNW as ‘the logical culmination of international law and the conviction of the [UN] General Assembly regarding the intrinsically immoral nature of nuclear weapons’.2 Mexico also delivered a closing statement to the NPT Review Conference on behalf of 65 TPNW-supporting states that 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, Mexico said that it has ‘proudly promoted and will continue to promote’ the TPNW. It described the Treaty as ‘complementary’ to, ‘fully compatible’ with and ‘mutually reinforcing’ of the NPT, and ‘a tangible expression of the obligations under its Article VI’. It also said that ‘The TPNW gets more and more signatures and ratifications and continues, inexorably, its path towards universality.’4
- Mexico should continue to encourage other states to adhere to the TPNW.
- Mexico should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
