In December alone, the CPI edged up 0.1 percent from a year ago, according to the National Bureau of Statistics (NBS).

The core CPI, which excludes food and energy prices, rose 0.4 percent from a year ago last month, up from 0.3 percent in November.

On a monthly basis, the CPI was flat in December, following a 0.6-percent decrease in November.

For the full year of 2024, the PPI declined 2.2 percent, smaller than the 3-percent drop in 2023.
