China's Producer Price Index (PPI), a main gauge of inflation at the wholesale level, remained unchanged in February from a year earlier, the National Bureau of Statistics (NBS) said Friday.

The zero-growth reading, the lowest since December 2009, further eased from 0.7 percent in January, after hitting a 31-month high of 7.5 percent in July last year, NBS data showed.

On a month-on-month basis, the country's February PPI grew 0.1 percent from January, the NBS said in a statement on its website.

Meanwhile, producer purchase prices grew 1 percent year on year in February and 0.1 percent from a month ago, it said.

In the first two months of this year, the PPI climbed 0.4 percent year on year, while producer purchase prices gained 1.5 percent during the period, the NBS said.

The NBS also announced that the year-on-year growth of the consumer price index, a main gauge of inflation, dropped to 3.2 percent in February, the lowest pace since June of 2010.
