This is a sound tactical move to provide a hedge against future US economic threats.

Strategically, I do think you want to be coming up with a plan to shield core industries like auto, shipping, energy, and some parts of manufacturing (eg “factories for factories” rather than “factories for consumer goods”) from dumping / state subsidies.

It might be OK to let the PRC subsidize your solar cells, assuming you can build wind instead if they try to squeeze you. It’s probably not wise to depend on PRC for your batteries, drones, and cars, where these are key to strategic autonomy and you don’t have an alternative.
