If you have been in discussion with the Chinese state sponsored trolls, you probably heard the argument that the United States is putting sanctions on China to decrease China's rise to becoming the next superpower.
These trolls are paid for by the Chinese Communist Party to influence popular opinion in western countries and and other places such as India, Russia and Japan.
The main reason this argument is flawed is because China is not a free and open country. Most skilled people are not likely to immigrate to China for jobs or working on new technological innovations. Phd's and scientists are not flocking to China.
That's why China is only good at copying stuff not building them. In the end, China's own policies will prevent it from becoming a superpower.
Recently China opened up some of its universities to overseas students. They're trying to gather talented students from across the world. But so far this policy has not shown any noticeable results.
China will continue to copy western technologies and they aren't going to become the next superpower with their copied weapons and products.
