for me its not a open society. Chinese citizen’s don’t live in what Karl popper calls a open society. and although he was a Libertarian he has a good point. a open society is a society where you have freedom of speech meaning you can criticize the government a society where you have the right to assemble and march for political goals. this is important as it allows for minority’s to stand for better treatment by there neighbors. it also allows for society to develop based on a output by the minority resulting in a society where less people suffer.
It should be said, because you said “China’s workers are exploited just like many capitalist countries”, that China often gets blamed for the working conditions in Taiwan and Hong Kong. And foreign business owners set the working conditions in mainland factories. The government has been doing a lot to reduce the “sweatshops”, which includes putting restrictions on foreign business owners and nationalizing industries that tend to be hotbeds for poor working conditions.
But, it should also be stated, that (something like) 1 in 5 workers are a part of the communist party, and thus get a voice in their community about workers rights. Chinese workers aren’t being exploited in the same ways American workers are, despite American corporations trying to exploit them the same. You can read the previously supplied links for a better understanding of that. Regardless, you seem to be assuming the foreign business owner’s factories represent the working rights of the entire nation, which is untrue.
