I don't see EU making a deal with China that lets them sell their slave built cars without tariffs. As I feel it there are a lot of public opinion against buying Chinese cars atm. Some did like 5 years ago but not any more. They are almost as dead as Tesla.

German car makes do have issues, but I'm sure they will work it out.
