Kirin will become Karen
Anything Huawei had as tech in its Kirin processor, can simply be farmed out to other Chinese makers. So unless you're planning to sanction all Chinese chip makers this is a non-issue.
Realistically you cannot sanction all Chinese chip makers because of this:

Chinese GDP is 27 trillion, USA 20 trillion, EU 18 trillion, India 11 trillion. It isn't that GDP of China has suddenly shot up, USA massively inflated their dollars, PPP GDP doesn't recognize the fake US $ the Fed prints as GDP, so it tends to balloon "manufacturing and services" countries over "prints money and hands it to billionaires" countries.
They'll change the name from "Kirin" to "Karen" and it won't be manufactured by Huawei, but business is business.
I can't help but think Xi would have been better to give Trump his quid-pro-quo, it would have done less harm to the US economy. Look at Mexico and NAFTA, a quick meeting, some quid-pro-quo exchanged, and the cancelled NAFTA becomes NAFTA 2, slightly more favorable to Mexico, but ultimately also, less damage to the US economy.
