If by heavy subsidies you mean - encouraging internal competition, securing cheap energy and educating thousands of engineers then yes, Chinese cars are subsidized.
If by heavy subsidies you mean pocketing 150 billions of dollars from EU R&D budget for innovation that have never happened then no, Chinese cars manufacturers are not subsidized.
> Thanks to heavy subsidization of the industry by Chinese government to gain an competitive advantage.
You can't have a functional government that serves the interests of it's people and enables the country to dominate increasingly more sectors!
It's basically cheating!
The government has to be dysfunctional, and should only collect disproportionate taxes with the idea that they'd be wasted extremely inefficiently.... on god knows what, some bullshit, some "social programmes" and "culture" and the dumbest things imaginable - whatever they might be, but not anything that's actually ... you know good for the country!
