Tokyo, Jan. 21 (Jiji Press)—The U.N. treaty to ban the production, possession and use of nuclear weapons has started taking effect in countries that ratified it by October last year.

Among the 50 signatories, Kiribati and other island countries in the South Pacific became the first to see the nuclear weapons ban treaty coming into force on Friday, the day of effectuation in respective time zones.

The landmark international treaty was adopted in 2017 with support from 122 nations and regions at the initiative of nonnuclear weapons states frustrated with long-stalled disarmament talks. It met the requirement of having 50 member states as Honduras ratified it in late October.
