China's factory-gate inflation cooled in June to the lowest in 15 months.

The producer price index (PPI) rose 6.1 percent year-on-year, the National Bureau of Statistics (NBS) said on Saturday, after a 6.4 percent rise in May. That was a faster rate than expectations of 6.0 percent growth tipped in a Reuters poll.

The consumer price index (CPI) increased 2.5 percent from a year earlier, widening from a 2.1 percent gain in May and the highest in 23 months. In a Reuters poll, the CPI was expected to rise 2.4 percent.

The CPI stayed flat month-on-month, after the 0.2 percent drop in May, beating the 0.1 percent decline in a Reuters poll.
