Chinese Premier Wen Jiabao on Tuesday called for China and the United States to work closely to make contributions to a steady recovery of global economy.

The essential task of the two countries at present is to overcome difficulties and impacts brought about by the economic downturn, Wen said during a meeting with Lawrence Summers, head of U.S. President Barack Obama's National Economic Council, and Deputy National Security Adviser Tom Donilon.

"China and the U.S. should work together to properly deal with problems and consolidate the foundation for a better relationship in future," he said.

Wen said a positive, cooperative and comprehensive China-U.S. relationship was in the fundamental interests of the two countries, and should be promoted unswervingly.

"Dialogue and cooperation are at the heart of Sino-U.S. relations, and the influence (of them) is unprecedented," he said.

Wen proposed the two countries deepen political trust, respect the other's core interests, not interfere in the other's internal affairs and not take the other as an adversary.

The U.S. officials told Wen that the Obama administration valued relations with China because the two countries share common interests and the ties will greatly influence the world's future.

The United States wanted to promote high-level contacts and frank talks, deepen strategic trust and cooperation, and properly handle any problems so to improve bilateral ties, according to them.

They also reaffirmed that the United States will adhere to one-China policy.
