Russia on Monday warned it would go after any European state that sought to take its assets after reports that the European Union is looking for new ways to leverage hundreds of billions of dollars of frozen Russian assets to help Ukraine.

The U.S. and its allies prohibited transactions with the Russian central bank and finance ministry after President Vladimir Putin sent his army into Ukraine in 2022, and blocked $300-$350 billion of sovereign Russian assets, mostly European, U.S. and British government bonds held in a European securities depository.
