Not to worry. China can’t fake those kinds of chips, at least not yet. Intel, AMD, TSMC (which makes most of the chips that are put into automotive applications) are beyond the manufacturing ability of the Chinese. More importantly, the validation tools these chipmakers give to their customers virtually guarantees ‘fake’ chips can’t be used.
Where these chips might find their way into US products is in appliances and other lower-ticket products that don’t use sophisticated chips.
The major chip makers are Chinese - Taiwan Chinese TSMC - not, as you say, Mainland CCP China.
I wouldn't be so sure. As we've seen with "the Big Guy" who gets his 10% cut of everything it seems, China does a damn' good job of buying people off or compromising them to guarantee that they (China) gets what it wants.
