Nuclear-weapon-free state

Has signed the TPNW

Has not yet ratified the TPNW

Peru has signed but not yet ratified the Treaty on the Prohibition of Nuclear Weapons.

Antonio García Revilla, the director-general of multilateral and global affairs at the foreign ministry of Peru, signed the treaty on 20 September 2017. 

Peru participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.

In September 2020, the president of Peru, Martín Vizcarra, announced in a video message to the UN General Assembly that Peru is in the process of ratifying the treaty, “convinced that the prohibition of nuclear weapons and tests continues to be a moral imperative for the planet and the human species”.

In a statement to the United Nations in October 2019, Peru said that it signed the treaty because the use of nuclear weapons “constitutes a crime against humanity and a serious violation of international law” and would have “catastrophic consequences for all humanity”.

It said in September 2019 that “this legally binding instrument will not detract from the current disarmament and non-proliferation regime; on the contrary, it will strengthen and complement it”.

Peru has promoted universal adherence to the treaty, including by co-sponsoring a UN General Assembly resolution in 2019 that calls upon all states to sign, ratify, or accede to the treaty “at the earliest possible date”.

In a statement to the United Nations in September 2017, Peru said that it hopes “that all states possessing [nuclear] weapons will join this instrument”.

In its opening statement to the negotiating conference, Peru said: “What does not exist cannot cause harm. Nuclear weapons simply should not exist.”

In 2016, Peru was a co-sponsor of the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

Peru was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the negotiations.

Peru is a state party to the 1967 Treaty of Tlatelolco, which established Latin America and the Caribbean as a nuclear-weapon-free zone.
