Of course the Chinese create things, but they also specialize in copying US technology because we still create and commercialize faster than they do (to generalize).
To further generalize, most creation in the electronics industry is done by companies in the US, Japan, Germany, Scandinavian countries, S.Korea and perhaps even Taiwan. Of course, China is learning fast. But, copying western technologies is still rampant there. They are much better at copying than we are because many companies there make all their money off of copies...they are very efficient at it.
