The dialogue has opened a new chapter of the China-US dialogue.

The dialogue mechanism is a result of an important consensus reached by Chinese President Hu Jintao and his US counterpart Barack Obama during their meeting in London on April 1.

It is also a strategic measure to boost the China-US mutually beneficial cooperation in various fields, and the healthy and stable development of China-US ties in a new era.

The mechanism, a fruit of the 30-year-old China-US relationship, reflects the inevitable tendency in the development of the Sino-US relations and the world situation.

Over the past 30 years, the China-US ties, especially in trade and economic fields, have constantly matured, creating an interdependent, win-win situation of common development.
