Chinese Premier Wen Jiabao has warned that the country is still facing various uncertainties ahead despite signs of economic recovery, saying the government will maintain the macro economic policies.

"There are still a lot of unstable and uncertain factors ahead and the economic situation ahead is still very grave, although both the world economy and the national economy are making positive changes now," Wen said during an inspection tour to east China's Zhejiang Province from Saturday to Monday.

He said there have been increasingly more positive signs in the country's economic performance, but stressed that the country's economic recovery is still "unstable", "not consolidated", and "unbalanced" and warned against blind optimism.

Chinese President Hu Jintao said on July 23 that the country would maintain its macro economic policies, a week after the country reported a rebound in growth in the second quarter.

Wen echoed Hu's comments on July 27 to say that the country should stick to its proactive fiscal policy and moderately easy monetary policy for a sustained growth during a visit in northeast China's Jilin Province.
