The US Treasury Department, led by Secretary Scott Bessent, announced an expansion of secondary sanctions against entities and countries that maintain business ties with Iran. The new measures target five sectors: digital assets, technology, gold, aviation, and shipping, which the Iranian government uses to prop up its economy. Nearly 60 entities, individuals, and vessels have been sanctioned, but no major Chinese banks are being targeted despite China's significant oil imports from Iran. The move aims to cut off Tehran's economic lifelines and is part of a broader effort by the Trump administration to escalate economic pressure on Iran.
