All examples you've mentioned are product of very good policy implemented by Chinese Govt. decades back. Most of these factories were set up by foreign companies or helped by those companies to setup and produce goods based on material of process of their selection. No or very little innovation involved in it.
It helped China in long run. Now Chinese product are almost on par with normal brands out side China. But even today Chinese more inclined to choose product made out side it they get choice.
you've zero knowledge about what happened in china, please don't make up fake stories. "all set up by foreign companies?" are you joking? The foreign companies were doing charity?
If you don't know it, let me give you some data, now China is No. 1 in patent application, No.2 in patent granted, according
to World Intellectual Property Organization (WIPO)
The patent filing and keeping process are costly games, so don't take it like a student writing a trash paper for graduation.
China also spends 2rd largest amount of money on R&D, and generates 2rd largest amount of scientific papers as well.
In terms of high quality scientific paper, Nature Publishing Index (NPI) set by NATURE magazine said that China is now No.4 in the world, next to US, UK, and Germany, and will probably take over Germany's position this year.
I can not post links now, but you can easily find those results with google.
