China’s Commerce Ministry says it urges the US to immediately correct "erroneous practices" and lift Iran-related sanctions against relevant Chinese companies

Historically these exchanges have rarely produced actual delisting; the more common sequence is a formal protest, sometimes mirrored retaliation or a working-list addition of US firms, and then the matter recedes until the next round of designations. The channel that matters is not the diplomatic language itself but what it signals about enforcement scope, since sanctions touching Chinese companies affect the specific named entities' dollar access and counterparties' willingness to deal, with spillover into freight, insurance and the dark-fleet crude trade that moves sanctioned barrels. The distinction worth drawing is between primary sanctions on the companies and secondary-sanction exposure for banks and refiners handling Iranian flows, where behaviour actually changes. Follow-ons to watch are whether Washington responds or escalates, whether Beijing adds counter-measures, and any shift in enforcement against the intermediaries rather than the headline entities. As rhetoric, this is routine; the tell is action, not wording.
