It sounds like you don't have a problem.
Also, the use of 'hand over' suggests they are all the way not willing to disclose the intellectual property but were forced to, but isn't there a patent system in China? Why would these companies refuse to disclose some intellectual property and make use the legal system, just as how they did it back home?
This isn't a new thing. It's been going on for decades. Huawei is a stolen corporation that would not exist if not for theft of technology, intellectual property, and trade secrets. It would further not exist if the Chinese market were as open as the American market and Huawei was forced to compete on a level playing field domestically.
These companies are after profit, so they chose to go to China to earn that profit. And for that profit, at some point in time, they must have deemed acceptable to give up something in exchange. Isn't this what trading is all about? Now somebody regrets they shouldn't have made certain choice, so they blame it on the other government? Be an adult.
Most of the companies when those joint ventures were setup were promised or told that their intellectual property was secure. It was then stolen and they were left with regret. Companies which refused to take that risk were compromised by Chinese actors and had their IP taken by force.
For many years the US has had to stop IP theft from China: (example: https://www.justice.gov/opa/pr/us-charges-five-chinese-milit...) and this is simply a cumulation of those efforts.
The blame on China is more than fair.
In the US, economic espionage is illegal and has been for some time, with legislation reinforcing that rule (such as the Economic Espionage act of 1996). If I as a private company engage in economic espionage I am liable to get prosecuted and may get time in prison. The same does not apply to companies in China, where economic espionage of a competitor is not only tolerated but encouraged.
The above linked suit was against individuals for economic espionage and not intelligence collection.
This requires the American company to hand over intellectual property and trade secrets. And then, amazingly, some state funded competitor comes along doing the same thing the American company wants to do.
Would a Chinese company have this same problem entering America??? No.
We need to treat China the exact way they treat us. The entire western world.
