People buy meat in a supermarket in Wuhan City, capital of central China's Hubei Province, Aug. 9, 2011. China's Consumer Price Index (CPI), a main gauge of inflation, accelerated to 6.5 percent in July, the National Bureau of Statistics (NBS) said on Tuesday. The stubbornly high inflation rate has been driven by increasing food costs, which rose by 14.8 percent in July from a year ago. [Xinhua]
