What do you mean "we don't know either way"? People can visit China and look around. China also sells technology so you could buy stuff and see how it works. They might be "covering up their shortcomings" but why would would they do that if that makes them lose customers? You can't sell technology based on hot air. It doesn't make any sense. What use is technology if you don't widely deploy it and commercialize it? It's not like China isn't one of the biggest trading nations in the world.
