Typical russian bogus.
Most european car producers have already plants in russia. VW for example. Since those cars are build inside russia they are not affected from any sanctions. Only 6% of european cars are actually imported into the russian market.
There is a much bigger problem our car makers face in russia. The economic crash there. VW already halted production on several days a week there in the russian plant and plans to fire the workers there. Food price in russia did rise 20% last two weeks. Most russians simply cant afford a new car.

last time China tried this, the EU crushed the chinese solar power industry like rats. The EU just installed such high import taxes on chinese solar cells, that the chinese corporations went down the drain.
