China (PRC) doesn't even have the second largest economy in the world. That's Japan.

If you include Taiwan, China just about rises above Japan, which, when you consider that Japan has a tenth of the population, a tiny fraction of the area, and very few raw materials, and that this is still a third of the economy of the USA, isn't overly impressive.
