Two White House officials — Lawrence H. Summers, the director of the National Economic Council, and Thomas E. Donilon, the deputy national security adviser — held meetings in Beijing on Monday and Tuesday that were aimed not at fashioning new pacts, but at maintaining a dialogue that had been strained at times in recent months.

“Strategic trust is the basis of China-U.S. cooperation,” said Dai Bingguo, a Chinese state councilor who met with them, the official Xinhua news agency reported.

Prime Minister Wen Jiabao told the two Americans that China and the United States should not view themselves as rivals, according to the Chinese state news media.
