NEW YORK, Aug 9 (Reuters) - Crude prices settled slightly lower on Thursday, extending the previous session's losses as the escalating China-U.S. trade dispute casts doubt over the outlook for oil demand.
Brent crude futures LCOc1 fell 21 cents to settle at $72.07 a barrel. U.S. crude CLc1 fell 13 cents to $66.81 a barrel.
Both benchmarks tumbled more than 3 percent on Wednesday after U.S. data showed a smaller-than-expected weekly draw in crude inventories and a surprise build of 2.9 million barrels in gasoline supplies.

The market has also been weighed down by concerns that trade disputes will curb demand. As retaliation against Washington, China will impose tariffs of 25 percent on a further $16 billion in U.S. imports ranging from fuel and steel products to autos and medical equipment. Crude oil will be exempt.
