WASHINGTON: The United States on Wednesday imposed fresh sanctions on Russia over the war in Ukraine, targeting a network that Washington accused of procuring military and dual-use technologies from US manufacturers and supplying them to Russian users.

The US Treasury Department said it imposed sanctions on Russian national Yury Yuryevich Orekhov, whom it accused of being a procurement agent, and two of his companies - Nord-Deutsche Industrieanlagenbau GmbH and Opus Energy Trading LLC.

Deputy Secretary of the Treasury Wally Adeyemo said sanctions and export controls imposed by a broad coalition of allies had left Russia increasingly struggling to secure "inputs and technologies" for its war.

"We know these efforts are having a direct effect on the battlefield, as Russia’s desperation has led them to turn to inferior suppliers and outdated equipment," he said in a statement.
