US-China rivalry will shape the 21st century - Financial Times

Assume that by 2040, China achieves a relative GDP per head of 34 per cent at market prices and 50 per cent at PPP. This would imply a dramatic slowdown of the rate it is catching up (a fall of around 70 per cent from the rate since 2000, starting in 2023). China’s economy would then be almost twice as big as that of the US at PPP and almost 30 per cent larger at market prices. (See charts.)
