The mainland's consumer price index (CPI), a main gauge of inflation, remained unchanged from a year ago in July, data from the National Bureau of Statistics showed on Saturday.

The producer price index (PPI), which measures costs for goods at the factory gate, went down 3.6 percent.

On a month-on-month basis, the CPI edged up 0.4 percent, against a 0.1 percent drop in June and above an expected 0.3 rise.

The 3.6 percent decline in the PPI missed economists' forecast of a 3.3 percent slide. It fell 3.6 percent in June too. (Xinhua/Reuters)
