China's consumer inflation rate quickened to 2.5 percent in January from a year earlier, the highest since May 2014 and beating market expectations.
Analysts polled by Reuters had predicted the consumer price index (CPI) would rise 2.4 percent, the biggest gain in nearly three years, versus a 2.1 percent gain in December.
The producer price inflation rate accelerated to 6.9 percent, the National Bureau of Statistics said on Tuesday, compared with the previous month's rise of 5.5 percent.
The producer price index (PPI) rose the fastest since August 2011.
The market had expected producer prices to rise 6.3 percent on an annual basis.
Inflation expectations have been rising in most major developed economies, except Japan, since mid-2016 in line with a global recovery in manufacturing, which has boosted prices of crude oil and other resources such as iron ore.
That has sparked talk of tighter monetary policy, though consumer inflation in Chinais believed to be still well within the central bank's comfort zone.
