March 20, 2025 · Treasury announcement
Iranian oil purchasing and shipping network sanctioned
Treasury designated a Chinese refinery and transportation network, attributing approximately $500 million in Iranian oil purchases to Shandong Luqing.
Before the action
The February maximum-pressure directive had already set reducing Iranian oil exports to zero as a policy goal. Treasury subsequently identified refinery purchases and transportation arrangements as channels supporting Iranian oil revenue, including trade involving the Shandong Luqing refinery in China. I1I2
What the U.S. did
Treasury announced sanctions against the refinery and associated oil transportation network. Its account attributed approximately $500 million in Iranian oil purchases to Shandong Luqing, connecting a specific buyer and shipping activity to the administration’s broader effort to constrain oil revenue.

What the record establishes
The announcement documents designated parties and Treasury’s grounds for targeting them. It establishes an implemented sanctions action in the government record, while the cited purchase figure describes attributed transactions rather than a verified amount of funds recovered, frozen or prevented.

Costs, durability & open questions
The source does not establish that every transaction was directed by China’s government or that the full cited purchase amount was blocked. Actual revenue reduction, evasion, replacement buyers and the durability of restrictions require additional evidence beyond the designation announcement. I1I2
