Iranian oil offers to Chinese buyers fall as US blockade bites, sources say
XLE•Sanctions risk keeps buyers on alert
On Thursday, U.S. Treasury Secretary Scott Bessent threatened Iran with "the toughest sanctions in history," with details to come on Monday, to pressure Iran to reopen the Strait of Hormuz and end the war.
That has China's independent refiners on alert for further sanctions targeting specific buyers, a source at one of the plants said.
However, the source said new sanctions were unlikely to significantly deter purchases, noting that refiners which have been previously sanctioned continued processing Iranian oil.
China, the world's biggest crude importer, buys more than 80% of Iran's shipped oil, according to 2025 data from Kpler. Beijing has said it rejects unilateral sanctions, and a Chinese foreign ministry spokesperson said on Thursday sanctions will not solve the conflict.
Iranian oil exports plunged to only 100,000 bpd by July 2019 after the U.S. further enforced sanctions and China temporarily suspended purchases.
