 "Oil prices slide on worries over China economy and higher crude output")
By Jessica Jaganathan
SINGAPORE (Reuters) - Oil prices fell on Monday on worries over China's economy after a survey showed factory activity growing at its slowest pace in 17 months in the world's second-largest oil consumer, concern compounded by a rise in oil output from OPEC producers.
Brent crude oil futures skidded 81 cents, or 1%, to $74.60 a barrel by 0116 GMT while U.S. West Texas Intermediate (WTI) crude futures dropped 69 cents, or 0.9%, to $73.26 a barrel.
"China's been leading economic recovery in Asia and if the pullback deepens, concerns will grow that the global outlook will see a significant decline," said Edward Moya, senior analyst at OANDA.
"The crude demand outlook is on shaky ground and that probably will not improve until global vaccinations improve."
China's factory activity expanded in July at the slowest pace in nearly a year and a half as higher raw material costs, equipment maintenance and extreme weather weighed on business activity, adding to concerns about a slowdown in the world's second-biggest economy.

Also weighing on prices, a Reuters survey found that oil output from the Organization of the Petroleum Exporting Countries (OPEC) rose in July to its highest since April 2020, as the group further eased production curbs under a pact with its allies and top exporter Saudi Arabia phased out a voluntary supply cut.
