Latest developments

In a press statement, the foreign ministry said that Peru's ratification of the TPNW highlights its 'high commitment to its obligations under international human rights and humanitarian law', adding that it 'is in line with Peru’s commitment to promoting international peace and security to facilitate the development and growth of our peoples'.2

Addressing the 2021 UN General Assembly, the Foreign Minister of Peru, Óscar Maúrtua, hailed the TPNW’s entry into force as a 'great achievement' and 'a legal and moral starting point on a long road to achieve nuclear disarmament'.3

Peru was also one of the co-sponsors of the 2021 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'.4


  • 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.
