> It is unclear how the chip made its way to Huawei. In 2019, the company released its Ascend 910 chip series. At the time, prior to export controls, the chips were produced by TSMC, two sources told Reuters earlier this year.
The question of why the US has the right or power to tell TSMC, a Taiwanese company, who it is allowed to do business often comes up in these discussions. I've often seen the response that this is US technology, and that any country would apply similar controls to its own technologies. What I don't think people realize is that these sorts of "secondary" controls are very unusual, internationally.
The US imposes controls on goods manufactured abroad using US-made tools or intellectual property. This is a bit like the way that the GPL "infects" other projects, and forces them to abide by its terms, and to my knowledge, the US is the only country that does this (in any case, it's the only country doing this on such a large scale). If you think of how integrated the world economy is, these sorts of "infectious" controls are extremely disruptive.
