Costa Rica

Nuclear-weapon-free state

Has joined the TPNW

Signed: 20 September 2017

Ratified: 5 July 2018

 

Summary

Costa Rica has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.

 

Signature and ratification

Luis Guillermo Solís, the then-president of Costa Rica, signed the treaty when it opened for signature on 20 September 2017. Elayne Whyte Gómez, the permanent representative of Costa Rica to the United Nations in Geneva, deposited the country’s instrument of ratification with the UN secretary-general on 5 July 2018.

Costa Rica was the 11th state to ratify or accede to the treaty.

Addressing the United Nations ahead of the signing ceremony in 2017, Solís said: “This treaty is a strong message that most UN member states do not support, do not accept, and do not consider nuclear weapons as legitimate, and that the international community clearly states that nuclear weapons are not only immoral, but are henceforth illegal.”

Universalisation

Costa Rica has promoted universal adherence to the treaty, 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 September 2019, the president of Costa Rica, Carlos Alvarado Quesada, said that “the treaty bolsters the political standard-setting, humanitarian and legal imperatives of nuclear disarmament, which are the prime objective of this organisation”.

 

Treaty negotiations

Costa Rica participated in the negotiation of the treaty 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, Costa Rica described the task at hand as being “to fill the existing legal void” and “to add to international law a chapter that should have been written long ago”.

Costa Rican ambassador Elayne Whyte Gómez served as president of the negotiating conference. Upon gavelling through the treaty on the final day of the conference, she remarked: “We have managed to sow the first seeds of a world free of nuclear weapons.”

In 2016, Costa Rica 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

Costa Rica 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.
