China's GDP soared 11.1 percent in the first half of 2010 to reach 17.28 trillion yuan ($2.55 trillion), said the National Bureau of Statistics (NBS).

The Chinese economy has returned to good health while many other countries are still reeling from deep gloom, said Sheng Laiyun, spokesman of the NBS.

It is still necessary for the government to maintain flexible policies and respond to uncertainties ahead, he said.

China enjoyed strong growth rates in early 2010 in part due to a low comparison base last year, said Zuo Xiaolei, chief economist at the Beijing-based China Galaxy Securities Co. Ltd. But now the comparison base has become more demanding.

Ha Jiming, chief economist at the China International Capital Corp. Ltd. agreed. With investments tapering off and bank lending slowing, the economy is bound to lose some steam, he said.

The top priority of the country now is to rebalance the economy and foster consumption as well as the service industry, said Ha.
