China will continue to achieve rapid but stable economic growth in 2007, the head of the National Development and Reform Commission, China's top economic planning agency, said on Wednesday.

Ma Kai told a news conference during the annual session of the National People's Congress, China's parliament, that while fixed-asset investment had been brought under initial control, the economy still faced pressure for an investment rebound.

Ma added that the 10.7 percent growth that China achieved last year was within a normal range.

"There were no big ups or downs, meaning the stability of the economy improved," Ma said.

He added that the 8 percent growth target outlined by Premier Wen Jiabao on Monday was not cast in stone, and could be adjusted.
