WASHINGTON - Any deal reached at climate change talks in Copenhagen must include a mechanism to ensure transparency and that all parties are fulfilling their obligations, the White House said on Thursday.

White House spokesman Robert Gibbs said the United States believed there was still a chance of deal, but China needed to give ground on the U.S. demand for transparency. He said if reports were true that China was balking at a climate deal, the United States hoped it would reconsider.
