China's macro-economic policy would remain "consistent" and "stable" to consolidate a base for economic recovery, vice premier Li Keqiang said Tuesday.

Chinese Vice Premier Li Keqiang addresses the opening ceremony of a High Level Forum on the Northeast Asia Economic and Trade Cooperation held in Changchun, capital of northeast China's Jilin Province, Sept. 1, 2009.

Although positive factors are accumulating and momentum apparently growing, China's economy still faces many difficulties and challenges as the international financial crisis is still not over, said Li at the opening ceremony of the 5th China Jilin Northeast Asia Investment and Trade Expo, in the northeastern city of Changchun, the capital city of Jilin Province.

He said the government would continue to stimulate consumer spending, push forward economic restructuring and facilitate foreign investment to energize enterprises and maintain persistent and steady economic expansion.

The revitalization of northeast China, which is known as the country's old industrial base, would play a key role in coordinating regional economic expansion and spurring domestic demand.

Northeast Asian nations are highly complementary in economic development. Strengthening economic and trade cooperation in this region would play a positive role in boosting regional development and the world economy, Li said.

China is willing to enhance cooperation with countries in the region with more open and positive attitudes to realize win-win results, he said.

The six-day exposition, which started on Tuesday, focuses on opportunities and challenges in coping with the global financial crisis.
