China's GDP was only predicted to beat the USA GDP using a Purchasing Power Parity conversion. Purchasing power parity conversion factor is the number of units of a country's currency required to buy the same amounts of goods and services in the domestic market as U.S. dollar would buy in the United States.
For instance the World Bank estimates that 419 yen will buy the same amount of goods and services in China as $100 would in the United States. But if you exchange $100 in China you should get 618 yen.
The opposite happens in rich countries. You need 87 Euros in France to buy as much as US$100 does in America. But if you exchange $100 you will only get 76 Euros.
So as China gets richer, then the prices will go up and the PPP conversion factor should also go up, so that theoretically it could be the same as the exchange rate.
But to bolster the question raised by "le roi" this kind of conversion factor is computer for some statistical average, but in real life it is almost meaningless. If you go to Podunk, Iowa a $100 will buy you much more than in Manhattan. Similarly for Shanghai vs a tiny rice paddy.
