Hu's visit is expected to reaffirm the responsibility of the two countries in safeguarding world peace and stability.

China and the United States share an extensive ground for cooperation and shoulder important common responsibilities in dealing with many major issues regarding world stability and prosperity.

It is crucial to further strengthen their coordination and cooperation, with a view to jointly tackling the challenges and striving to boost world peace, security and prosperity.

Fu Mengzi, a researcher with the Beijing-based China Institutes of Contemporary International Relations, said China-U.S. cooperation will benefit not only both countries, but the Asia-Pacific region and the world at large as well.

That is because of the increasing interdependency among countries and regions in this era of globalization, he said.

The visit also will serve as a link between the past and the future.

During President Hu's visit in 2006, China and the United States acknowledged that they share extensive and important common strategic interests.

At a meeting in London in April 2009, President Hu and U.S. President Barack Obama agreed to make joint efforts to build a positive, cooperative and comprehensive relationship for the 21st century.

Without doubt, Hu's upcoming visit will present China-U.S. relations with a new look.

If the China-U.S. relationship is likened to a ship sailing on the sea, then bilateral strategic cooperation is the ship's rudder, while pragmatic cooperation is its engine.

President Hu's visit is a trip that would charter a new course for China-U.S. practical cooperation, and benefit both sides and the world at large.

During the visit, China and the United States are expected to sign a package of new cooperation documents, and bilateral pragmatic cooperation would be lifted to a new stage.

Bilateral trade is expected to top 380 billion U.S. dollars in 2010. China has been the fastest-growing market for U.S. products for nine consecutive years.

There is also huge potential for furthering China-U.S. practical cooperation as better coordination between the two sides is needed in balancing the world economic structure and bilateral trade level is needed to be lifted up.

For example, the United States has not recognized China's market economy status and still imposed restrictions on high-tech export to China. Lifting these trade barriers will surely further boost bilateral trade.

Further China-U.S. practical cooperation is also a necessity for world growth.

Up to now, as the root cause for the global financial crisis has yet to remove, the world economy still lacks strong momentum for recovery. Under these circumstances, China-U.S. cooperation is crucial for boosting reform of the international financial system and speeding up the world economic recovery.

China-U.S. cooperation also plays an important role in solving many major regional and international issues.

The two countries can cooperate more in easing tensions on the Korean Peninsula, settling the Iranian nuclear issue, combating international terrorism, fighting climate change, reforming the United Nations, and reducing cross-border crime, among other things.
