Chinese inflation has hit its second 10-year high in two months, led again by a further sharp rise in meat prices.
Rising pork prices have pushed up inflation in China
China's rate of consumer price inflation hit 6.5% in the year to August, up from 5.6% in July, said the National Bureau of Statistics.
Meat prices have risen 49% over the past year, caused by a shortage of pork after a series of disease outbreaks.
China's central bank has raised interest rates four times already this year to try to control inflation.
China, the world's biggest consumer of pork, has seen its pig population decline by 10% over the past year as a result of major outbreaks of blue-ear disease.
The Chinese government has moved quickly to stamp out the problem, but pork imports have surged as domestic supplies try to recover.
Beijing is said to be acutely aware that while the country's growing urbanised middle class can cope with the higher food prices, it is a major problem for the country's rural poor, who make up most of the population.
Non-food prices rose just 0.9% in the year to August.
"The risk is that if the economy continues to grow very rapidly, this inflation, which looks concentrated in food, starts spreading," said Rob Subbaraman, chief Asia economist for Lehman Brothers in Hong Kong.
