BEIJING – China's consumer price index (CPI), a main gauge of inflation, rose 1 percent year on year in June, official data showed on Thursday.

The core CPI, which excludes food and energy prices, also increased 1 percent year on year, according to the National Bureau of Statistics (NBS).

On a month-on-month basis, CPI edged down 0.3 percent in June, the NBS data revealed.

Thursday's data also showed that China's producer price index, which measures costs for goods at the factory gate, went up 4.1 percent year on year in June.  

On a month-on-month basis, PPI dipped 0.3 percent last month, the data showed.

Analyzing the monthly changes, NBS statistician Dong Lijuan said lower international crude oil prices drove down prices in related domestic industries, while seasonal factors led to divergent price trends in the broad energy sector.

Meanwhile, faster industrial upgrading boosted demand and lifted prices in some sectors such as new materials and industrial robots.
