China's gross domestic product (GDP) is expected to rise by 10.5 percent in 2006, the Chinese Academy of Social Sciences (CASS), a major official think tank, said in a report.

The CASS report, made available to Xinhua Wednesday, also forecast that the country's economic growth rate would slow to 10.1 percent in 2007, thanks to the government's macro control policies.

The National Bureau of Statistics had earlier estimated the country's growth in the first half year at 10.9 percent.
