China’s financial regulator tells major banks to temporarily halt new lending to five refiners that the United States recently sanctioned, according to people familiar with the matter cited by Bloomberg. The directive is linked to the refiners’ alleged ties to Iranian oil, which is the basis for the US sanctions. The reports say the regulator’s guidance applies to China’s largest banks and is intended as a temporary measure rather than a permanent ban. The companies involved are described as refiners newly sanctioned by the United States, but the accounts provided do not specify additional operational details beyond their connection to Iranian oil. The information is presented as coming from sources familiar with the discussions, and it does not include comments from the regulator, the banks, or the affected refiners. Overall, the development highlights financial compliance steps Chinese banks may take in response to US secondary sanctions risk associated with the Iran-related activities of counterparties.
