Huawei Technologies Co. roared back into the spotlight this past week after a Bloomberg report showed their new phone is powered by a 7-nanometer processor, which is just a few years behind Apple’s iPhone. And who’s getting the jitters over this new development? Those very same Capitol Hill lawmakers, who, for the last several years, sanctioned not only Huawei but also China’s chip sector to stymie homegrown tech progress. That move didn’t pan out as planned.

Now, the US Commerce Department is panicking while it rushes to understand how sanctioned Huawei was able to design and manufacture a 7-nanometer processor for its new Mate 60 Pro smartphone. The whole purpose of blacklisting the company and many other Chinese tech firms was to restrict access to US technology to make these sorts of devices.
