Good for them.
The US is going to use every dirty trick in the book to suppress China's technological and economic development, so why on earth should they play by the "rules"?
Maybe because China hasn't played by the rules in years. Thus, the United States had many reports from businesses that got their information stolen, and the U.S. got tired of all the intellectual theft, and started doing something about it.
Look at all the attempts (Over 100 times) the Chinese have used to try to copy/steal the F-16 turbine. The Chinese admit they have stolen the F-35 tech.
Years ago, a good friend of mine was contracted through his company to a Chinese company to develop wind turbine technology. The software was property of his company, and they sent him to China to help integrate the software to their turbines. About 2/3 of the way through the development, the Chinese company cancelled the contract, and sent my friend home, with no explanation. About 2 years later, my friend got a phone call to fix the software in a turbine. He showed up to the site, and there was his company's software, in use on a Chinese wind turbine. Come to find out, the Chinese had stolen the software, and marketed it as their own, with their turbines. The Chinese did not develop it. They stole it, and marketed it all over the earth.
I could go on and on.
Intellectual theft, industrial espionage, and military espionage are real. China is one of the best at doing it. It doesn't make it right.
