LONDON - World oil prices rebounded Friday, reversing earlier losses, as traders speculated that the Chinese government could implement more stimulus measures to combat weaker economic growth. Brent North Sea crude for delivery in August rallied $1.16 to $102.23 per barrel in late morning deals in London. New York's main contract, light sweet crude for August, jumped 74 cents to $86.82. Oil prices had fallen in earlier Asian trade after news that economic growth in China, the world's largest energy consumer, slowed to its lowest level in three years during the second quarter.
