Secondary sanctions are working as designed
A US sanctions enforcement official would argue —When Treasury designates a refinery subsidiary, the goal isn't only to stop one cargo — it's to force the parent company, its bankers, and its suppliers to publicly account for what's actually moving through their pipelines. That's exactly what happened here: within days of the designation, one of China's largest independent refiners had to issue a stock exchange filing swearing off Iranian crude and producing supplier guarantees. Markets and counterparties now have a paper trail to hold them to. Tehran's revenue depends on independent Chinese teapots being willing to take discounted barrels with plausible deniability. Pierce the deniability, raise the compliance cost, and the discount Iran has to offer widens. That is how you squeeze the regime without firing a shot.
