RIYADH: Oil prices were little changed on Friday but were set for a weekly rise amid optimism that economic stimulus efforts will prompt a recovery in China, but a stronger dollar capped gains, according to Reuters.  Brent crude futures fell 2 cents to $73.24 a barrel by 08:35 a.m. Saudi time. US West Texas Intermediate crude was at $69.61, down 1 cent, from Thursday’s close. However, on a weekly basis, Brent was up 0.4 percent and WTI rose 0.2 percent.
