NEW YORK (Reuters) - U.S. Treasury Secretary Henry Paulson said on Thursday he agreed with Congress that China needs to move more quickly on letting the yuan appreciate, but that "firm engagement" was better than legislation to achieve these means.

"I happen to believe that the most effective way and the right way to get movement over time will be ... very firm engagement on our part through our strategic economic dialogue and enlisting the support of countries around the world," Paulson told Fox News in a television interview. "I think that will prove to be more effective than through legislation."
