I think such prophecies are greatly exaggerated, since it's rare that a developed country "gets taken over" by another country. The only cases that come to mind would Germany and Japan after WW2 and even these bounced back and took back control. And that was after WW2, so after huge disruptions.

But, getting back on track, things are different. China is 10x the size of Japan. If China's GDP per capita gets at least close to that of Japan's, they will both double the world's economy and also become 50% of it, like the US was a few decades ago. They will dwarf everyone, including the US. So there will definitely be a huge Chinese influence, world wide.
