Minimum prices protect EU’s major auto nations from too much Chinese EV plants in new EU countries. There are still likely to be some, especially if they can sell below minimum price at least in home country.

Higher Chinese profits can be deployed into charging infrastructure, services, and more model imports. More EVs.

While tariffs in EU weren’t meant to be prohibitive (no EU models are at full tariff rate), the new policy would be friendlier, likely for purposes of having China make friendly EU business policies.
