The Trump administration is dramatically expanding US sanctions to capture subsidiaries of blacklisted companies — a crackdown that drew a swift rebuke from China, where key tech giants are already subject to stringent American trade curbs.

A long-awaited rule published Monday by the Commerce Department seeks to prevent sanctioned companies – such as Huawei Technologies Co., China’s AI chip champion – from using affiliates to access restricted US goods.
