Expansion of both consumer, producer price indices edging down in June China's producer and consumer prices registered slower growth in June thanks to the country's recent efforts in stabilizing commodity and raw material prices, leaving more room for macro policy maneuvers in the second half of this year, officials and experts say. Data released by the National Bureau of Statistics on Friday showed that expansion of both consumer and producer price indices edged down in June. The country's consumer price index, a main gauge of inflation, rose 1.1 percent in June, down from 1.3 percent in May, putting CPI expansion at 0.5 percent year-on-year for the first half of this year.
