This sounds like official Chinese propaganda. This was truer at some point, but things have started turning bad for China with the advent of Xi Jinping. 20-25 years ago, the country was hopeful, developing fast, opening up. Foreigners started moving there, seeing it as a new land of opportunity. Much of that is gone. The economy is in bad shape, youth unemployment is massive, the country is a dictatorship, nobody wants to move there (and China doesn't want you to anyway). I'll quote the Economist: "When Mr Xi took over in 2012, China was changing fast. The middle class was growing, private firms were booming and citizens were connecting on social media. A different leader might have seen these as opportunities. Mr Xi saw only threats."
