I can't remember mate. I didn't make it up, but without trawling the internet I don't have a link. I'm quite prepared to accept it was wrong, but given I did hear the stat from somewhere, and given the Forbes numbers I quoted above, I find it very hard to believe that the US is so far ahead. I would imagine its quite close and that China will overtake soonish. When you have an economy that's complaining about "only" growing at 7% per year, combined with their pretty unrestrained capitalism then I would say that's actually inevitable.
