China revised the volume of its gross domestic product (GDP) for 2008 to 31.4045 trillion yuan (US$4.45 trillion) from the previous 30.067 trillion yuan (US$4.26 trillion), the National Bureau of Statistics said Friday.

The revision will have a small impact on China's 2009 economic growth, Peng Zhilong, director of the national economy accounting department under the bureau, told reporters at a news conference after China carried out its second economic census.

China's economic growth in 2008 is 9.6% changed from 9.0%, an official at the National Bureau of Statistics said Friday.
