WASHINGTON (Reuters) - A bipartisan group of 32 senators on Monday urged China to show "concrete progress" on beef, intellectual property and other trade irritants at a high-level meeting next week with U.S. officials.

The group, representing nearly one-third of the Senate, also urged China to let its currency "to appreciate meaningfully in advance of President Hu's visit" to the United States, which is expected Jan 17-20.
