Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Peru described the TPNW as ‘an instrument that, in a legal and practical sense, complements the NPT and reinforces the legal framework for nuclear disarmament’ and ‘a significant step forward in the process of eliminating nuclear weapons.’2 In a closing statement to the NPT Review Conference, Peru and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.3

Marking the International Day for the Total Elimination of Nuclear Weapons on 26 September 2022, Peru said that it has promoted the TPNW ‘as part of its humanitarian commitments’. The failure of the recent NPT Review Conference ‘reaffirmed the relevance of the TPNW as the path to follow until nuclear weapons are entirely eliminated’, it said.4

In the First Committee of the UN General Assembly in October 2022, Peru emphasised the ‘great importance and relevance’ of the TPNW in advancing nuclear disarmament.5

Peru was one of the co-sponsors for the 2022 UN General Assembly resolution on the TPNW, which called upon ‘all States that have not yet done so to sign, ratify, accept, approve or accede to the Treaty at the earliest possible date.'6


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

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