That the US is actively controlling for this risk indicates that it is probably already doing it towards other nations (e.g. US intelligence agencies have been building in "spy components" and "kill switches" into exported automobiles for decades).
The US threw in Russia to make it look like they weren't singling out China. Cuz where are Russian EVs to have software that's a threat to the US?
Any way, the same logic could be used for any electronics device, so the US is effectively forcing a de-coupling of supply chains, in an attempt to isolate China. This was always going to be the inevitable end result of the US economic war and attempt at reindustrialization.
The question is what is China going to do about it. Aside from the usual "sell more to the Global South" and "ban more US products," there has to be an effort to improve internal markets. Self-sufficiency cannot just be on the production side; it also has to be on the consumption side. An export-based economy like South Korea has no choice but to kneel to its largest customers. China should strive to be the largest customer, as well, and that means both improving Chinese consumption and improving Chinese demographics.
