"We hope the United States will carry out appropriate economic policies and maintain fiscal and financial stability to protect the interests and confidence of investors," Wen said at the opening of the three-day World Economic Forum's annual meeting in China's northeastern city of Dalian, China's state-run Xinhua news agency reported.
The Chinese leader said the United States currently faces the tasks of controlling its external debt, reducing the fiscal deficit and creating jobs through economic growth.
"We believe the United States is capable of overcoming difficulties and achieving a full economic recovery," Wen said.
He repeated Chinese calls to allow its businesses to invest more in the U.S. markets and loosen restrictions on U.S. exports to China, which would help job creation.
Wen said China is willing to launch large-scale financial and economic cooperation with the United States.
