Sounds like a realist.
The other possibility is the bell curve. China is only beginning to exploit their population for athletic development in an organized way. Their population is really big.
Olympic athletes come from the far right side of the Bell Curve. The population of people out there is much bigger in a population of 2 billion than it is in a population of 300,000,000. And the odds of producing someone really really far out there is greater.
China will eventually dominate all sports events if it stays together as a political entity and if it continues to do a good job identifying freakishly gifted athletes at a young age and training them.
