Some of the electronics obtained through the scheme have been found in Russian weapons platforms seized in Ukraine, prosecutors said. They used a German company to ship the military technologies, as well as Venezuelan oil, to Russian purchasers, prosecutors said. The U.S.-origin technologies can be used in fighter aircraft, ballistic and hypersonic missile systems, smart munitions, and other military applications, Treasury said. After the initial round of U.S. sanctions on PDVSA, Russia's Rosneft emerged as a key intermediary for Venezuelan crude. After Washington sanctioned Rosneft subsidiaries over their dealings with PDVSA, dozens of firms with no track record of oil trading have been intermediating in sales of Venezuelan oil to Chinese buyers.
