I think there are structural reasons why China won’t be the next hyperpower - demographics being key and the recent demographic reversal. China is also surrounded on all sides by rivals, including a rapidly growing India. I also haven’t read Dalio except in a very cursory way - but his love of citing Confucius to explain Chinese society has always puzzled me, since Confucius is more pop psychology and sociology in post-Mao China than real table stakes. So take that for what it's worth.

That said, China will be a very strong regional power at least for quite a long time barring regime collapse, and the United States seems to have expanded Monroe to mean the world at this point...
