"The bullish (Chinese) data, combined with the expectation that OPEC will leave its oil production quota unchanged at 30 million barrels per day ... has supported the U.S. benchmark," said a report from Sucden Financial Research in London.
Delegates from some of the world's key oil producers, including Saudi Arabia, Venezuela and Nigeria, will meet Wednesday at OPEC headquarters in Vienna.
An estimate from analysts at JBC Energy in Vienna showed OPEC's crude output fell to 29.44 million barrels a day in November, the lowest since May 2011 and the third straight month with output below 30 million. Most of the difference was attributed to production and export snags in Libya, where political volatility and the effects of the 2011 civil war continue to affect the oil industry.
Meanwhile, Brent crude, a benchmark for international oils, was down 35 cents to $109.34 a barrel on the ICE Futures exchange in London.
