* Wall St mixed; hopes for banks' clean-up offset economic fears
* China exports tumble, weighing on dollar, world prospects
* Europe, Asian stocks end up as financials rise

NEW YORK, March 11 (Reuters) - Hopes that the U.S. government would speed up a plan to clean up bank balance sheets supported U.S. and European stocks for the second day on Wednesday, but sentiment remained fragile and trading was volatile as bad economic news continued to make the headlines.
A plunge in China's February exports was the most remarkable reminder of the magnitude of the global recession. The news weighed on the dollar and on commodities, while an overall cautious sentiment cushioned a fall in the prices of safe-haven U.S. Treasuries.
"I don't know why people think you're going to get a solution overnight when it took years to get into the problem," said Joe Saluzzi, co-manager of trading at Themis Trading in Chatham, New Jersey. He was referring to expectations that the U.S. Treasury would soon come up with a detailed plan to remove toxic assets from banks' balance sheets.
Such expectations grew after U.S. Treasury Secretary Timothy Geithner said last night he wanted to make it "compelling" for banks to clean up their balance sheets.
Geithner also said he would quickly work out details for financing bad asset sales. The Dow industrials were down slightly, while the S&P inched up and the Nasdaq held a moderate gain at 13:57 p.m. (1757 GMT).
The Dow Jones industrial average <
> was down 2.23 points, or 0.03 percent, at 6924.26, while the Standard & Poor's 500 Index <.SPX> was up 0.58 of a point, or 0.08 percent, at 720.18. The Nasdaq Composite Index < > gained 9.75 points, or 0.72 percent, to 1,368.03.In Europe, the FTSEurofirst 300 index <
> rose 1.76 points, or 0.25 percent, to close at 692.65, supported by the financial sector.Despite Geithner's comments, the International Monetary Fund said developed economies are moving too slowly in ridding banks of their non-performing assets. [

DOLLAR SLIPS AS CHINA'S EXPORTS DROP
Still, demand for stocks helped the U.S. dollar weaken against major currencies, with the U.S. Dollar Index <.DXY> down 0.64 percent.
The euro <EUR=> was up 0.71 percent against the dollar, at $1.2760. Against the Japanese yen, the dollar <JPY=> was down 1.07 percent at 97.63.
The greenback was also pressured by news that China's exports slid 25.7 percent in February from a year earlier, sharply exceeding the forecast for a 5.0 percent drop. [
]The report cast doubts on China's ability to finance the U.S. current account deficit in the long run, clouding the prospects for the U.S. currency.
"The concern is that maybe China will not be able to generate massive amounts of foreign exchange capital which can then be recycled to U.S. Treasury securities," said Boris Schlossberg, GFT's director of FX research. "That is the big fear factor that hangs over the dollar."
Meanwhile, U.S. Treasury debt prices fell after a record large sale of 10-year notes drew below-average demand. The benchmark 10-year U.S. Treasury note <US10YT=RR> was down 1/32, with the yield at 3.016 percent, while 30-year U.S. Treasury bonds <US30YT=RR> declined 18/32 to yield 3.761 percent.
The decline in Treasury debt prices was partially contained, however, by lingering concerns about the state of the global economy.
Investor caution also pressured commodity prices in general, while keeping gold prices higher.
U.S. crude oil <CLc1> fell $1.21 to $44.50 per barrel. Spot gold prices <XAU=> rose $13.00, or 1.45 percent, to $908.80. The Reuters/Jefferies CRB Index <.CRB> of 19 commodity futures was down 1.97 points, or 0.95 percent, at 205.67.
