China's consumer inflation moderated more than expected in October, while producer prices extended their decline to the 44th straight month, flagging persistent deflationary pressure in the world's second largest economy.

The October consumer price index (CPI) rose 1.3 percent from a year earlier, compared with 1.6 percent in September, National Bureau of Statistics (NBS) data showed on Tuesday. The reading came in below expectations of a 1.5 percent rise, according to a Reuters poll of economists.
