China already enacted foreign investments law. Tesla uses it to enter the Chinese market freely. Build factories, sale electric vehicles, enjoy all tax and subsidy that local companies are. And so will VW, and any other auto maker. IP protection is strengthening as well. In the areas of internet service there is still the internet security law, which requires all internet services providers to store data locally and moderate content. Google fb Twitter doesn't want to comply so they don't operate in that market. Apple, Amazon, Microsoft, Uber, Airbnb and more are complying so they are operating in China. In other sectors, it's already open access to Chinese market and equality between local and foreign businesses. China is responding to criticisms.

Can I buy shares of Chinese companies when I am not a Chinese citizen? Until that happens I am not buying what you are saying.
