China's move at the weekend to allow greater flexibility for the yuan should help improve the Sino-U.S. relationship, the U.S. ambassador to China said on Monday.

It takes an irritant off the table on the U.S.-China relationship, Jon Huntsman told reporters, after a speech to mark the end of this year's U.S.-China Strategic and Economic Dialogue.

Huntsman also said Beijing's move on the yuan is a genuine attempt to provide greater flexibility to the exchange rate mechanism. (Reporting by Sui-Lee Wee, Writing by Don Durfee, Editing by Ron Popeski)
