WASHINGTON - A Chinese expert on international relations emphasized Wednesday that the basis of China-U.S. cooperation is still "solid", dismissing the "gloomy" picture of bilateral ties that some media have painted.

"There is an increasing interdependency between China and the US," Su Ge, president of China Institute of International Studies, said at the Brookings Institution. "Hence, the two countries need to have more cooperation."

Problems in the world are becoming more and more complicated and need to be resolved through concerted efforts by countries in the international community, including the US and China, said Su, who previously served as Chinese ambassador to Suriname and Iceland.

Su believed that there has been growing convergence of interests between China and the U.S., citing "effective cooperation" between the two sides in multilateral organizations such as the UN, the Group of 20 and Asia-Pacific Economic Cooperation, and on a wide range of regional and international issues including Iran nuclear talks, counterterrorism and climate change.

Noting that China has been a benefactor of the existing world system, Su said he saw no reason for China to move to upset the whole basis of international order.

What China desires is a stable regional and international situation for its domestic development and reforms, he said.

Speaking of the upcoming state visit by Chinese President Xi Jinping to the U.S., Su said the summit between Xi and his U.S. counterpart Barack Obama will leave an important historic legacy that would have an impact on the bilateral relations in the years to come.

"The visit and the summit meeting will open up new prospect for mutually beneficial cooperation between the two great countries," Su said.
