Elmau, 27 June 2022 (dpa/MIA) - The United States is imposing sanctions on state-owned Russian defence enterprises in order to "limit Russia's ability to replace the military equipment it has already lost during the brutal war against Ukraine," a senior White House official says. Speaking on the sidelines of a G7 summit in southern Germany, the official said Washington will implement a higher tariff rate on more than 570 groups of Russian products worth approximately $2.3 billion. US President Joe Biden and his fellow G7 leaders would seek authority to put any revenues derived from tariffs on Russian goods towards the Ukrainian war effort, he said.
