LONDON (Reuters) - Oil prices rose on Tuesday after evidence of tightening supplies in the United States, the world's biggest oil consumer, outweighed concerns for the health of the Chinese economy.
China's giant manufacturing sector is shrinking, economists say, as domestic demand falters, fanning worries that its economy may be slowing more sharply than feared.
Asian stock markets skidded to 3-1/2-year lows on Tuesday and the dollar sagged.
But the outlook for the U.S. economy looks brighter and oil supply there seems to be tightening, with one report estimating a drawdown of over 1 million barrels last week from the Cushing, Oklahoma delivery hub for U.S. crude.
Brent crude oil was up 55 cents at $47.89 a barrel by 1340 GMT after dropping 2.5 percent on Monday. U.S. light crude oil was also up 45 cents, at $44.88.

Lower oil prices may have begun to reduce production in the United States, but the world still faces an oil glut.
"U.S. output (is) showing firm signs of slowing," Rhidoy Rashid, oil analyst at consultancy Energy Aspects told Reuters Global Oil Forum. "Prices must hold at this range for around the coming six months for rebalancing to occur properly."
