Saudi Arabia's crude oil supply to China is set to decline in February from the month before, trade sources said on Thursday, after the kingdom hiked its prices and as OPEC+ extended production cuts in the first quarter.

Oil futures settled with a loss on Wednesday after the U.S. Energy Information Administration reported that commercial crude inventories fell for a seventh straight week, but gasoline and distillate stockpiles climbed by more than 6 million barrels each.

Crude oil prices rose to a three-week high amid mounting concerns over supply disruptions and increasing demands. However, technical analysts caution that oil markets may be over-bought.
