NEW YORK, Aug 20 (Reuters) - Global stocks rallied and oil prices edged higher on Thursday after an equity rebound in China, some solid corporate results, and a bright spot in mixed U.S. economic data all helped to reassure investors about the recovery outlook.
Both the U.S. dollar and yen edged lower in thin trade as gains in global stock markets and upbeat U.S. regional manufacturing data eroded the safe-haven demand for the two currencies.
But yields on U.S. Treasury debt mostly fell in choppy trade as weak U.S. labor market data offset the surprise rise in mid-Atlantic factory activity, renewing doubts about how strong or sustained any U.S. economic rebound might be.
Crude prices rose slightly to near a seven-week high as optimism over the U.S. economy and signs of rising fuel demand outweighed the increase in new U.S. jobless claims.
Global sentiment improved after Chinese stocks <
> jumped 4.5 percent in their second-biggest daily percentage gain this year, easing concerns about an almost 20 percent slide in China's equity markets over the past two weeks."Investor sentiment appears to be oscillating between risk aversion and relief on a session-by-session basis," said Sreekala Kochugovindan, a strategist at Barclays Capital.
"However, the past month has been characterized by declining volumes typical of the summer holiday season. History suggests that trends established during periods of low trading volumes have swiftly petered out once volumes picked up."
World stocks as measured by MSCI <.MIWD00000PUS> were up 1.4 percent. U.S. stocks rose for a third straight session after the S&P 500 and Nasdaq suffered their worst day in about seven weeks on Monday.
Financial stocks contributed the most to gains in U.S. stocks. Citigroup <C.N>, the most active stock on the New York Stock Exchange, rose 8.5 percent after an analyst said some investors bet the share price will triple in three years.
AIG Inc <AIG.N> surged 21 percent to $32.30 after newly appointed Chief Executive Robert Benmosche told Bloomberg the bailed-out insurer may be able to repay its federal debts and boost value for shareholders. [
]"Just the fact that the more-important jobless claims were overshadowed by the manufacturing data and rebound overseas shows how much optimism there is in the market now," said Dan Faretta, a senior market strategist at Lind-Waldock in Chicago.
The Dow Jones industrial average <
> closed up 70.89 points, or 0.76 percent, at 9,350.05. The Standard & Poor's 500 Index <.SPX> was up 10.91 points, or 1.09 percent, at 1,007.37.

Oil markets have been tracking stocks and the U.S. dollar, as well as broad economic indicators, for signs the recession may end, which could foreshadow rebounding fuel demand.
Treasuries gains were mostly modest, with shorter maturity notes unchanged.
"The mixed news kind of leaves (Treasuries) paralyzed," said Kim Rupert, managing director of global fixed income analysis at Action Economics in San Francisco.
