Over seared scallops and beef tenderloin, Treasury Secretary Timothy F. Geithner urged his counterparts from Europe, Canada and Japan to help persuade China to let its currency, the renminbi, rise in value — a crucial element in redressing the trade imbalances that are threatening recovery around the world.
But the next afternoon, the annual meetings of the International Monetary Fund ended with a tepid statement that made only fleeting and indirect references to the simmering currency tensions.
The divergence between the mounting anxieties over Chinese policy and the cautious official response was a striking display of the difficulty of securing international economic cooperation, two years after the financial crisis began.
Above all, officials say, the crisis has shifted influence from the richest powers toward Asia and Latin America, whose economies have weathered the recession much better than those of the United States, Europe and Japan.
