More subsidies than the $7,500 per vehicle subsidy that the US government gives for our EV vehicles?

To be fair you can’t really use this type of subsidy for price dumping in foreign markets like China is doing in Europe and would love to do as well in the US.

Wages and hence manufacturing costs are higher in the US

are you sure they are subsidizing them and not simply producing them more cheaply?

China are subsidising the entire supply chain.

It's a moot point. China won't be able to continue to do this for much longer.
