Russia's envoy to the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) said Friday that Moscow will revoke its ratification of the pact, a move that Washington denounced as endangering "the global norm" against nuclear test blasts.
The announcement by Mikhail Ulyanov added new fuel to tensions between Russia and the United States over Moscow's invasion of Ukraine and arms control disputes between the world's largest nuclear powers.
Ulyanov, Moscow's envoy to the treaty, said on X, the social media platform formerly known as Twitter, that "#Russia plans to revoke ratification (which took place in the year 2000) of the Comprehensive Nuclear-Test-Ban Treaty."
