Global oil prices fell more than 1% on Monday, backsliding last week's gains, as questions over China's economy outweighed OPEC+ output cuts and the seventh straight drop in the number of oil and gas rigs operating in the United States.
Brent crude was down 78 cents, or 1%, to trade at $75.83 a barrel, after falling as much as $1.27 to $75.34, Reuters reported.
US West Texas Intermediate crude was down 76 cents, or 1.1%, to $71.02, after declining by $1.15 to $70.63.
Last week, Brent posted a gain of 2.4% and WTI rose 2.3%.

China is widely expected to cut its benchmark loan prime interest rates on Tuesday, following a similar reduction in medium-term policy loans last week to shore up a shaky economic recovery.
Sources have told Reuters that China will roll out more stimulus support for its slowing economy this year.
