The U.S. Treasury Department is issuing sanctions on 21 people and 9 companies over Russia’s actions in Ukraine and its annexation of Crimea, which the U.S. does not formally recognize, the AP reports.

What it means: This could ramp up tensions between the U.S. and Russia — U.S. Secretary of State Rex Tillerson met Friday with Ukraine’s president in Switzerland just a month after the U.S. reportedly approved a lethal arms sale to Ukraine amidst the ongoing conflict last month.
