Costa Rica
Costa Rica was at the forefront of the diplomatic process towards a treaty prohibiting nuclear weapons, and Costa Rica’s Permanent Representative to the United Nations in Geneva, Ambassador Elayne Whyte Gómez, chaired the negotiations in 2017 that resulted in the adoption of the TPNW. Costa Rica is a state party to the TPNW from 22 January 2021 and is in compliance with all of the prohibitions in Article 1 of the Treaty.

Latest developments
In First Committee of the 2020 UN General Assembly, Costa Rica pointed out that 'any initiative to prevent the proliferation of nuclear weapons must be joined by a parallel initiative to eliminate all nuclear arms, in a verifiable, irreversible and transparent manner. Costa Rica is also concerned by the apparent lack of urgency and seriousness with which solemn commitments continue to be approached, particularly with respect to nuclear disarmament.' Costa Rica invited all those States that have not yet done so to sign and ratify the TPNW, which it called a 'historic instrument, which complements and strengthens the NPT.' See: bit.ly/3lRYQp7.
Recommendations
- Costa Rica should continue to encourage other states to adhere to the TPNW.
- Costa Rica should ensure that all the TPNW obligations are implemented domestically, through legal, administrative and other necessary measures.
