The Biden administration imposed Tuesday what it said was the first tranche of sanctions targeting Russia for its actions against Ukraine.

The measures include freezing the assets of two state-owned banks that service the Kremlin and Russia’s military as well as comprehensive sanctions on Moscow’s sovereign debt, effectively cutting the government off from Western financing.

“Russia will pay an even steeper price if it continues its aggression, including additional sanctions,” President Biden said in a televised address.
