Taiwan Semiconductor Manufacturing Company suspended shipments to China-based chip designer Sophgo after a chip it made was found on a Huawei AI processor, according to two people familiar with the matter.

Sophgo had ordered chips from TSMC that matched the one found on Huawei's Ascend 910B, the people said. Huawei is restricted from buying the technology to protect U.S. national security. Reuters could not determine how the chip ended up on the Huawei product.

Tech research firm TechInsights discovered the TSMC chip on Huawei's Ascend 910B when it took apart the multi-chip processor, a different source told Reuters on Tuesday. Alerted to the finding, about two weeks ago TSMC notified the U.S., the source said.

How do US restrictions factor in here? TSMC is a Taiwanese company with only one operational plant in the US, the majority are in Taiwan, China, and Japan.

US law permits US control over any company in the world that uses US technology.

US legal mechanisms for internationally enforcing US law are not like domestic enforcement mechanisms. The scenarios that the pro-China folks here are talking about involve a (completely unrealistic) switch in Taiwanese allegiance, that would make US economic enforcement less relevant, and US military enforcement a serious international risk.

There are just a lot of tankies commenting, and you have to be able to interpret their logic.

The US claim on TSMC, are based on it using ASML (Dutch) equipment which has patent licenses from US. I was just answering the puzzling US colonial power roots. There may come a point of challenging the colonial patent power, while still attempting to pay for the patent, or China's "delete America" program may get more allies or rebellion from the colonies.

China/BRICS is a much bigger market than US, and economics means figuring out a way to earn from all sides is motivated. US promises to isolate itself even more under Trump, and there is a limit to how much it will be respected.
