The United States and its allies plan new sanctions on more sectors of Russia's economy that are critical to sustaining its invasion of Ukraine, including military supply chains, Deputy U.S. Treasury Secretary Wally Adeyemo said yesterday, Reuters reported. Adeyemo, speaking in London on a European trip to consult with allies on strengthening and enforcing sanctions to punish Russia, said the broadening of those efforts was aimed at undermining "the Kremlin's ability to operate its war machine." The Treasury last Thursday slapped new sanctions on dozens of Russian defense companies, from makers of ammunition, missiles and helicopters used in the Ukraine invasion to radar and imaging systems firms. The sanctions freeze any assets they may have under U.S. jurisdiction and prohibit American entities from any transactions with them. "In addition to sanctioning companies in sectors that enable the Kremlin's malign activities, we also plan to take actions to disrupt their critical supply chains," said Adeyemo.
