South Korea's consumer prices grew at the slowest pace in four months in December, indicating that the country is keeping inflationary pressure under control, a government report showed Monday.

The country's consumer prices index rose 1.4 percent in December from a year earlier, slowing from a 1.6 percent on-year gain in the previous month, according to the report by Statistics Korea. From a month earlier, it grew 0.2 percent.

The on-year figure marked the slowest growth since August when the index increased 1.2 percent.

The core inflation, which excludes volatile oil and food prices, rose 1.2 percent on-year this month, which also represented a deceleration from a 1.3 percent increase in November. (Yonhap News)
