Latest developments
In the First Committee of the 2021 UN General Assembly, Costa Rica said that the TPNW 'shows us some ways in which it is possible to create a more inclusive and secure future for all'. It added that 'that future will only be possible when the nuclear-weapon states stop multiplying and modernising their nuclear arsenals, when the reductions are verifiable, transparent and carried out with the participation of the International Atomic Energy Agency'.1
Costa Rica was 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'.2
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.
