For months, US lawmakers have warned US Treasury Secretary Henry Paulson that patience was wearing thin as his economic dialogue with Beijing failed to produce breakthroughs on currency and other disputes.
Now, as he meets this week Chinese leaders, Paulson faces new pressure in Congress, where legislators have proposed measures that would punish Beijing for manipulating its currency.
"The problem is, there is very little they can do in the immediate future that will make Congress happy," said Andy Rothman, a China strategist for investment bank CLSA.

But Paulson's real target audience is as much Congress as Beijing.
"Paulson is going to be hoping to come back from the current trip with private whisperings and confidences that he can share with members of Congress so as to discourage drastic action," said Sherman Katz, a former trade lawyer and researcher at the Carnegie Endowment for International Peace in Washington.
Paulson has appealed for patience, saying the dialogue launched last December needs time to produce results on complaints about China's currency controls, product piracy, barriers to foreign entry into its financial industries and other issues.
Beijing has begun easing currency controls and taken steps to rein in its surging trade surplus. But Washington and other governments that have seen trade deficits with China soar want faster action.
Critics say Beijing keeps its currency undervalued by up to 40 percent, giving its exporters an unfair price advantage and adding to China's swollen trade surplus.
Last week, over Paulson's objections, a Senate panel approved a bill to require Treasury to identify and punish currency manipulators. Another measure proposed earlier would tighten the legal definition of currency manipulation to make China more likely to be cited.
Beijing says the yuan will eventually be allowed to trade freely on world markets.
But it says abrupt changes would hurt its underdeveloped banking industry and cause financial turmoil.
China revalued the yuan by 2.1 percent against the US dollar in July 2005 and has allowed it to rise by about 7.2 percent since then. Last week, it was trading at about 7.6 to one dollar. Financial analysts expect Beijing to let the yuan rise by an average of about 5 percent annually over the next few years -- far less than critics want.
Yesterday, Paulson began his latest China visit with a stop at Qinghai Lake to highlight environmental challenges amid the country's breakneck growth.
Paulson's stature as a former Goldman Sachs chief executive and personal lobbying of Congress have bought him time, analysts say. But China's supercharged economic performance is fueling arguments that it can afford to move faster.
The economy expanded by 11.9 percent last quarter -- the fastest quarterly growth in 12 years -- and the trade surplus jumped by 85 percent last month to US$26.9 billion.
Beijing's standing with critics of its trade record has been hurt by its disastrous string of safety complaints about products ranging from toxic toothpaste to faulty tires, Katz said.
