China's economic growth has boosted disposable wealth

The comments, although not official confirmation of the growth rate, are the first indication of the figure.

If confirmed, it means China's economy grew faster in the previous year than in 2003 and 2004.

It would also prove that the government's efforts to cool down sectors of the economy in danger of overheating have proved largely unsuccessful.

Government action

Growth in state-controlled industries, such as construction, which have largely driven China's economic boom, are being increasingly controlled by the authorities.

However, much of the recent expansion in the Chinese economy has come from the private sector in areas such as services and banking.

Previous forecasts have suggested China's economy would grow 9.4% in 2005, in line with the 9.5% growth seen in both 2003 and 2004.

Chinese output totalled 15.9 trillion yuan ($1.9 trillion) in 2004, 18% higher than was first estimated.

Official estimates for 2005 growth will be published later this month.
