UPDATE 2-US senators pledge China currency bill push

(Recasts lead, adds detail)

WASHINGTON, July 2 (Reuters) - A bipartisan group of four senior U.S. senators vowed on Wednesday to work together on a bill to pressure China and other American trading partners to maintain fair exchange rate policies, after a year of inaction in Congress on once red-hot China currency concerns.

Finance Committee Chairman Max Baucus and Banking Committee Chairman Christopher Dodd, both Democrats, said they met last week, along with ranking committee Republicans Charles Grassley and Richard Shelby, to discuss the next steps for currency legislation.

The meeting followed the recent visit of a high-level Chinese delegation to Washington for trade and economic talks.

"We pledged to continue working together toward legislation to address currency exchange rate regimes," the four senators said in a joint statement.

The Senate Finance and Banking panels passed separate bills a year ago to give the White House new tools to pressure countries that manipulate their currencies for a trade advantage.

However, partly because of a jurisdictional turf battle between the two committees, no further action was taken.

The yuan has risen over 20 percent against the U.S. dollar since China revalued its currency in July 2005. It hit a post-revaluation high in late trade on Wednesday.

However, many U.S. lawmakers believe the yuan remains significantly undervalued, giving Chinese companies an unfair advantage in international trade.

"During our meeting, we discussed the progress China has made to appreciate its currency as well as the urgent need for continued appreciation and exchange rate liberalization," the four senators said.

"We also discussed our legislative proposals to ensure that our global economic partners -- including the People's Republic of China -- maintain exchange rate regimes that are compatible with International Monetary Fund and World Trade Organization commitments and principles," they said.

The four senators said they agreed that 1988 legislation requiring the Treasury Department to semi-annually identify which countries are manipulating their currency to gain a trade advantage was "inadequate and in need of reform."

The renewed push for currency legislation comes as the White House is pressing for approval of free trade agreements with Colombia, Panama and South Korea that have faced stiff opposition in Congress.

Baucus and Grassley also have been in talks with the White House on a bill to expand federal aid for workers who have lost their jobs because of imports or companies moving overseas.

Many Democrats in both the Senate and the House of Representatives want to go beyond dealing with just currency manipulation to strengthen overall U.S. ability to deal with unfair foreign trade practices.
