Addressing the First Meeting of States Parties to the TPNW (1MSP) in Vienna in June 2022, Paraguay commented that the large and growing number of states adhering to the Treaty is ‘undeniable evidence of the important achievement that this Treaty signifies for the global architecture relating to nuclear non-proliferation and disarmament’.[1]

Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Paraguay said that the NPT and TPNW are complementary. It called for the success of the 1MSP to be replicated at the NPT Review Conference.2 In a closing statement to the NPT Review Conference, Paraguay and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.2

In the First Committee of the UN General Assembly in October 2022, Paraguay said that the declaration and action plan adopted by the 1MSP ‘not only presents us with a series of practical measures for the full implementation of the Treaty, but is also in line with the application of Article VI of the NPT.’ It also said that the declaration and action plan ‘are clear examples of political commitment and how we can collectively work towards the elimination of these weapons’, and called on states ‘that are not party to the TPNW to sign and ratify it without delay’.4 Paraguay was also one of co-sponsors for the annual UN General Assembly resolution on the TPNW in 2022.5


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

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