A CBS News investigation has uncovered that China continues to import Iranian oil in defiance of U.S. sanctions by using a secret maritime network known as the "dark fleet." These covert ship-to-ship transfers take place in international waters near Malaysia’s Riau archipelago, often without transponders or ship identification. China is believed to be purchasing up to 90% of Iran’s crude exports. The report coincides with new U.S. sanctions targeting an alleged Iranian shipping empire linked to Hossein Shamkhani. #DarkFleet #IranOil #ChinaSanctions #OilSmuggling #USSanctions #IranChina #EnergyPolitics #CBSInvestigation #GlobalTrade #MaritimeSecurity
