Economic growth in China is expected to hit 9.9 percent this year and 9.7 percent in 2009 while in emerging East Asia it will moderate to 7.6 percent in 2008 and 2009 from 9 percent in 2007 due to a global economic slowdown, sharp rise in food and energy prices and volatile financial markets, said a report by the Asian Development Bank (ADB).

The region's growth outlook is vulnerable to a higher-than-expected spike in inflation, protracted slowdown in the US and any further tremors in global financial markets, said the July issue of the Asia Economic Monitor (AEM).

Another ADB report in April forecasted that China's economy would expand by 10 percent this year and 9.8 percent the next.
