Cooperation is the way to address trade imbalance between China and the United States as well as the difficulties and frictions arising from it, Chinese Premier Wen Jiabao said Wednesday.

The U.S. should open its exports to China and ease related restrictions while promoting two-way investment, Wen said at a press conference right after the parliament's annual session. [More about the press conference]

"China is prepared to buy more from the United States," said Wen.

"I believe that cooperation between China and the U.S. is always better than confrontation. As long as we continue to move in this right direction, the business ties between China and the United States will enjoy sustained and sound growth," he added.

Wen said the two countries should create favorable conditions for mutual investment and enhance cooperation in infrastructure construction. China's investment in U.S.' infrastructure construction sector would be a win-win solution for helping boost employment of U.S. workers.

Wen also proposed expanding cooperation in high-tech fields, including new energy, new materials, energy conservation and aviation.
