BEIJING – China's consumer price index (CPI), a main gauge of inflation, rose 0.8 percent year-on-year in August, official data showed Wednesday. 

In the same month, the producer price index (PPI), which measures costs for goods at the factory gate, went up 3.8 percent year-on-year, according to data from the National Bureau of Statistics.

On a month-on-month basis, the PPI reversed a 0.7-percent decline in July to rise 0.4 percent in August, the data showed.

Explaining the month-on-month movement, the bureau's statistician Dong Lijuan said imported price pressures, particularly higher international crude oil and nonferrous metal prices, pushed up prices in some domestic industries, while industrial transformation and upgrading boosted demand and prices in some emerging sectors.

Seasonal factors also played a role, with stronger summer demand for electricity and coal lifting prices in related sectors, while high temperatures and rainfall weighed on construction activity and prices in related industries.
