China's economy is not growing at the pace it needs to overtake the US economy anytime soon, and definitely not to become this supposed "hyperpower." To compare the US overtaking the UK, to China vs the US is nonsense. The UK is a small island power that punches above its weight, while the US is a continental sized power with global power projection capability.
China's economy is now 3 times the size of Japan. Japan is now purchasing long range cruise missiles, F-35's, Aegis Ashore batteries, and setting up a string of antiship and antiair missiles along its southern island chain. How is that falling in line going? Try falling in line with the US.
Like I said, underestimate India at your own peril. Those demographic trend lines are NOT in China's favor.
I get a strong sense of wishful thinking and Chinese bootlicking from you.
