They're not even that cheap. I am unfortunately in the market for a car and as much as I'd like one of these mythical cheap Chinese EVs, they don't exist in Europe.
They're not cheap in Europe because of import and export tarrifs along with additional taxes that China and your country collect. The cars are relatively cheap for Chinese consumers.
All that is true, it's just funny that the reality stands in stark contrast to European politicians (who must also know that) claiming that cheap Chinese EVs are going to outcompete European EVs in Europe.
The EU is already very angry, but I have yet to see a Chinese EV available for less than a European one, and Tesla is probably the cheapest. At this point the Chinese or other new Asian EV manufacturers are only selling their top of the line models in Europe if any at all.
