SEOUL, Jan. 22 (Xinhua) -- Prices for goods and services among South Korean suppliers rose on the back of higher farm goods prices, central bank data showed Monday.

The producer price index (PPI) stood at 103.14 in December, up 0.1 percent from the previous month, according to the Bank of Korea (BOK).

It was a turnaround after falling 0.1 percent in November as farm goods prices went higher, offsetting the decline in raw material prices.

Prices for agricultural, livestock and fishery products gained 1 percent in December from a month earlier. Livestock product prices retreated 4.3 percent, but agricultural product prices advanced 6 percent.

Prices for industrial products were unchanged last month. Oil and coal product prices gained 1.2 percent, but those for primary metal products and electronic devices shed 0.4 percent and 0.7 percent respectively.

Services prices inched up 0.1 percent on higher room charges during the winter vacation season.

From a year earlier, the PPI rose 2.3 percent in December, keeping an upward trend for 14 months in a row.
