They should probably subsidize their own EV sector properly but I guess when you are run by a shadow government comprised primarily of fossil fuel corporations it gets in the way.

From another SCMP article:

It will not only look for support given to Chinese brands, but also European and other international brands with a presence in China.

This means Tesla, Volkswagen and BMW models made in China could all be subject to import duties – indeed, discriminating on the basis of brand nationality would go against World Trade Organization rules. It also leaves Germany, whose automotive industry is highly exposed to China, vulnerable to retaliation.

I am pretty sure they will only doscriminate against Chinese brands. WTO "rules" mean jack.
