After three decades, Sino-US relations have reached a historic point, and where they go next is a question for strategists from both nations.

Now that the US is becoming more rational in its policy toward China, the two sides should establish normal relations.

However, the sad fact is, there is still a lack of strategic mutual trust between the two nations, as their military ties lag far behind their economic and political relations, and each portrays the other with a certain degree of distortion. More diplomacy is required to foster healthy mutual relations.

China and US might differ greatly culturally and ideologically, but they also share common interests in strategic development. Harmonious Sino-US relations will benefit the whole world.

In the 21st century the world is becoming increasingly interconnected. History has entered a new era, characterized by globalization and mutual reliance. Global affairs can no longer be dominated by one power alone. This has posed a serious challenge to China and the US as they seek to renew positive interaction.

The 21th century not only produced technological progress, it also witnessed nuclear proliferation, terrorism and climate changes. To successfully deal with these problems requires international cooperation, especially among powers such as the US and China, and both countries' leaders need to be aware of their global responsibilities.

Therefore we sincerely send our best wishes to President Hu Jintao on his visit to the US.

May the two great countries join hands in coping with the challenges we face today, and establish a positive beginning for the new century.
