Wen said China's economy was developing as expected, and called on government officials at all levels to improve economic controls to avoid serious fluctuations, Xinhua reported Sunday. He said they should try to make price increases "acceptable" for both industry and the public.

Wen also called for efforts to protect farmland to ensure grain security, and to boost efforts to create jobs for low-income families and recent college graduates.

The premier's remarks were made during a three-day research trip to Jiangsu province and Shanghai from Friday to Sunday, the state-run news service reported.
