BUSINESS: "Porsche Introduces a Sedan in China, the Biggest Auto Market," by Keith Bradsher, New York Times, 20 April 2009.

The opening para says all:

Porsche unveiled its entry into the luxury sedan market here on Sunday night, the eve of the Shanghai auto show. It was the latest confirmation of the importance of the Chinese auto market and the first time that Porsche has entered a new market segment at an auto show outside Europe or North America.

Remember: in the global economy, power stems from demand, not supply.
