Consumer price inflation fell to a five-year low in China and producer price deflation deepened, increasing the likelihood of additional policy stimulus in the world's second largest economy.
The year-on-year inflation rate came at 0.8% for January, its lowest in five years, from the December rate of 1.5%. Analysts were expecting 1%.
According to the National Bureau of Statistics, declining food prices due to warmer weather and a bigger comparison base last year were the reasons for the drop in the inflation rate in addition to lower global oil prices.
The monthly inflation rate stood unchanged at 0.3% while the consensus was for a rise to 0.4%.
Another set of data showed that producer prices fell more than expected. The PPI index dropped 4.3% from a year earlier in January after registering a 3.3% fall in December. The consensus was for a 3.8% drop.
Analysts said the disinflation trend points to the likelihood of further rate cuts.
