NEW YORK, Dec. 14 (Xinhua) — Wall Street climbed in early trading Monday after Abu Dhabi surprisingly provided 10 billion U.S. dollars bailout to Dubai to help with its debt repayments.

Abu Dhabi’s pledge, which sent world stocks mostly higher, helps ease investor fears that the emirate will default on its debt and slow the global economic recovery.

The Dow Jones rose 28.04 to 10,499.54. Broader indexes also went higher. The Standard & Poor’s 500 index added 5.46 to 1,111.87, and the Nasdaq rose 11.65 to 2,201.96.

Meanwhile, Citigroup Inc., recipient of the biggest U.S. bank bailout, said it will pay back 20 billion dollars in bailout money it received as part of the government’s Troubled Asset Relief Program. Citigroup will raise the funds with a sale of 20.5 billion dollars of equity and debt.

Moreover, Exxon Mobil says it will acquire XTO Energy in an all-stock transaction valued at 31 billion dollars on speculation that U.S. emissions restrictions will spur increased demand for natural gas.
