Mexico

Nuclear-weapon-free state

Has joined the TPNW

SIGNED

20 September 2017

RATIFIED

16 January 2018

IN FORCE

22 January 2021

 

Status

Mexico has signed and ratified the Treaty on the Prohibition of Nuclear Weapons (TPNW). It was among the original 50 states parties to the treaty when it entered into force on 22 January 2021.

 

Signature and ratification

Luis Videgaray Caso, the then-secretary of foreign affairs of Mexico, signed the TPNW at a high-level ceremony in New York when it opened for signature on 20 September 2017.

In an address to the United Nations following the signing ceremony, Videgaray said that Mexico had signed the TPNW because “the existence of nuclear weapons poses a threat to the whole of humanity”.

Miguel Ruíz Cabañas, the assistant secretary for multilateral affairs and human rights, deposited the country’s instrument of ratification with the UN secretary-general on 16 January 2018. The Mexican senate had given its unanimous approval for ratification in November 2017.

Mexico was the fourth state to ratify or accede to the TPNW.

In a statement to the UN General Assembly in 2021, the secretary of foreign affairs of Mexico, Marcelo Ebrard, hailed the TPNW’s entry into force on 22 January of that year as a “milestone” and called upon all states “to welcome this development that contributes to a safer and more peaceful world”.

Implementation

In accordance with Article 2 of the TPNW, Mexico submitted a declaration to the UN secretary-general on 22 January 2021 confirming that it does not own, possess, or control nuclear weapons, has never done so, and does not host any other state’s nuclear weapons on its territory.

Per Article 12, Mexico has promoted universal adherence to the TPNW, including by co-sponsoring and consistently voting in favour of an annual UN General Assembly resolution since 2018 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 2019, Mexico encouraged all states that have not yet ratified the TPNW “to speed up their respective processes”, and in 2021 it said that the treaty’s entry into force had “strengthened the norm that stigmatises a type of weapon that is inherently immoral”.

 

TPNW negotiations

Mexico participated in the negotiation of the TPNW at the United Nations in New York in 2017 and was among 122 states that voted in favour of its adoption.

In its opening statement to the negotiating conference, Mexico described the TPNW as “a global extension of the various treaties that establish zones free of nuclear weapons” and expressed hope that “the collective will of the international community” convinces nuclear-armed states, in the near future, to adhere to the treaty.

Mexico, Austria, Brazil, Ireland, Nigeria, and South Africa comprised a “core group” of states that played a leading role in bringing the negotiations about and ensuring their ultimate success.

In 2016, Mexico initiated and co-sponsored the UN General Assembly resolution that established the formal mandate for states to commence negotiations on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”. 

 

Before the negotiations

Mexico 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 TPNW negotiations.

In 2014, Mexico hosted the second in a series of inter-governmental conferences on the “humanitarian impact of nuclear weapons”, in the state of Nayarit. The Mexican chair of the conference, Juan Gómez Robledo, concluded that a diplomatic process must be launched for the prohibition of nuclear weapons.

The Nayarit conference helped cement the idea that the prohibition of nuclear weapons is a necessary precondition for their elimination, based on experience with other types of indiscriminate weapons. It was hailed as “a point of no return” in the process to outlaw nuclear weapons.
