WASHINGTON - The United States is working to expand areas of practical cooperation with China while seeking to resolve or manage their differences, a senior U.S. official said Thursday prior to a major round of Sino-U.S. high-level talks.

Hosting a media briefing on the forthcoming seventh round of the Sino-U.S. Strategic and Economic Dialogue (S&ED) and the sixth round of High-Level Consultation on People-to-People Exchange (CPE), Daniel Russell, assistant secretary of state for East Asian and Pacific Affairs, said that the United States has worked year after year "to help make space for China's growth."

The special representatives for President Xi Jinping, Chinese Vice Premier Wang Yang and State Councilor Yang Jiechi will co-host the S&ED with U.S. Secretary of State John Kerry and Treasury Secretary Jacob Lew, who represent President Barack Obama. Meanwhile, Kerry will co-chair the CPE with Chinese Vice Premier Liu Yandong.

"We don't always see eye to eye. But the fact is that global challenges require that we cooperate. They require collaborative solutions," Russell said, noting that the two countries have a "very complex, very consequential relationship."

"We've welcomed China's emergence on the world stage and participation in the global system," he added.(Xinhua)
