Oil prices steadied on Monday as falling U.S. oil rig counts and signs of strong U.S. economic growth were balanced by a slump in Chinese imports, pointing to lower fuel demand in the world biggest energy consumer. Global benchmark Brent crude oil for March was up 30 cents at $58.10 a barrel by 0420 GMT (11.20 p.m. EST Sunday) after rising as high as $59.06 earlier in the session. The move ended a six-month slide that saw oil prices lose more than half their value.
