it is very ignorant to say that China does not even know about internal combustion engine.
I am sorry to say this but China already successfully developed its own hydrogen internal combustion engine with its own patent. And is arguably the second country to possess such tech after Germany, even America and Japan are still at experimental stage.
And China already developed its own fuel cell cars with its own IPR

And who said China ignores technology ?? FYI, China now has the world's second largest R&D budget overtook Japan and now only behind USA.
