The United States imposed sanctions on more than 30 people and vessels for their role in selling and transporting Iranian petroleum-related products as part of Tehran's "shadow fleet," the Treasury Department said.

Described as a key move in US President Donald Trump's "maximum pressure campaign" against Iran's oil industry, his administration imposed new sanctions Monday on individuals, entities and tankers in mainland China,

Treasury Secretary Scott Bessent stated, “Iran continues to rely on a shadowy network of vessels, shippers, and brokers to facilitate its oil sales and fund its destabilizing activities.” He warned that anyone involved in Iranian oil would face significant sanctions risk as the United States uses all available tools to disrupt Iran’s oil supply chain.
