Oil prices dropped on Friday, amid concerns over falling Chinese demand after the world's second-largest oil consumer ordered factories to reduce output over worries of excess capacity.
U.S. crude traded as low as $104.10, but by the session ended down 79 cents at $104.70. Brent crude fell 50 cents to $107, after touching a three-and-a-half-month high last week near $110.
Brent futures for September last traded down 70 cents near $107 per barrel. U.S. light crude for September was down nearly $1 under $105 a barrel.
Earlier in the day, Chinese stocks markets dropped after China's industry ministry ordered companies across 19 industries to close outdated capacity by the end of September. The news from China overshadowed a report showing U.S. consumer sentiment is at a six-year high.
