China and the United States are sharing more responsibilities and cooperating on a broader basis than in 1979 when they established diplomatic ties, Chinese State Councilor Dai Bingguo said Tuesday.

"We are living in a world where the shared interests among countries are expanding and their interdependence is increasingly strengthened," said Dai at a seminar to mark the 30th anniversary of diplomatic relations.

He suggested that the two sides seize chances to promote the sustained, healthy and steady development of bilateral relations.

The relationship had seen great achievements in the past 30 years, though successes and setbacks went along with the development, Dai said.

The landmark development not only served the well-being of the two peoples, but also for peace and prosperity of the world, which reflected the three Sino-U.S. joint communiques as the political foundation of the Sino-U.S. relationship, he said.

Dai said the Sino-U.S. relationship would develop healthily and stably, as long as the two sides worked together, from a strategic and long-term perspective, to deepen cooperation, accommodate and respect each other's concerns.

China had also seen tremendous changes since its reform and opening up, which started in 1978.

China's future had become more closely connected to the development of the world. A more prosperous, open and harmonious China would adhere to the road of a peaceful development, he added.

The two-day seminar starting Monday gathered senior diplomats, scholars and entrepreneurs from the two sides.
