HONG KONG, March 11 (Reuters) - Asia stocks rose on Wednesday after hopes Citigroup will deliver a first-quarter profit sparked an improvement in investor confidence, though grim Chinese export data sent dealers buying the U.S. dollar for safety.
While Beijing's efforts to prop up the economy were expected to really take hold in the third quarter, near-term prospects were in jeopardy as both exports and imports fell for a fourth consecutive month.
Major European stock markets were expected to rise as much as 0.9 percent, according to financial bookmakers, on nascent optimism for bank stocks, though UBS AG <UBSN.VX> warned before the market opened that its earnings will remain at risk for some time because of vulnerabilities on its balance sheet. [
]Citi, whose share price traded below $1 for the first time last week, was profitable in the first two months of 2009, the bank's chief executive said in a memo to staff, heaping pressure on the firm to post a quarterly profit after chalking up losses in the last five quarters totalling around $37.5 billion. [
]Wall Street jumped 6 percent in heavy volume overnight <.SPX>, helped by Citi and comments from an influential U.S. congressman that rules against short selling of stocks may be re-implemented in a month. [
]Asia's equity rally by comparison was tempered by questions over the nature of Citi's profits.
"With the U.S. government still examining ways to stabilise the bank if needed, we remain somewhat sceptical and are wary of the rally we have seen today in the equity markets which reminds us of the previous rounds of dead cat bounces we have witnessed," economists with United Overseas Bank in Singapore said in a note.

Tuesday's 5.1 percent rise on the MSCI all-country world stocks index <.MIWD00000PUS> was the biggest daily gain in three months.
A 4.4 percent rise in HSBC <0005.HK> led Hong Kong's Hang Seng index <

GLOOMY CHINA TRADE DATA
While the Citi news brightened views on stability in the banking industry, the economic picture was darkening.
Japanese wholesale prices in February fell at the fastest annual rate in nearly six years, suggesting deflation is worsening and strangling the world's second-largest economy. [
]Chinese trade data for February reflected further pullback in global demand, with exports falling 26 percent compared with a 18 percent slide in January. [
]"China has finally and spectacularly succumbed to world financial crisis on the export side, and it's difficult to see why that would improve in the short term," said Paul Cavey, economist with Macquarie Securities in Hong Kong.
