THE U.S. Treasury Department has imposed sanctions on more than 20 companies in a network that it said has long sent Iranian oil to China, days after negotiators from Iran and the United States concluded a fourth round of nuclear talks.
The network facilitated the shipment of oil worth billions of dollars to China on behalf of Iran’s Armed Forces General Staff and its front company, Sepehr Energy, Treasury said. Washington designated Sepehr in 2023.
