> You’re using numbers from five years ago.
I'm sure fresh numbers are available, they're just unpublished.
We could do some educated guessing here - in the last 5 years China's economy grew at the rates of 8.6%, 3%, 5.4%, 5%, 5%, the US grew at 6.5%, 2.5%, 2.9%, 2.8%, 2.2%. We can extrapolate the manufacturing numbers based on that, which would give some advantage to the US because the US manufacturing lags the average, while the Chinese leads it.
The math gives us the current values for
World: $19.4 T, (%6.5,%3.4,3x%2.9)
China: $6.3 T - 32.5%,
US: $2.9 T - 15%.
