The industrial output index fell 3.2% in February on the month after a 2.4% gain in January, whereas the retail sales index jumped 5.3% last month after a 1.1% drop in January, the Statistics Korea data showed.

The sluggish factory output in February was led by semiconductors and automobiles, with production dropping 17.1% and 4.8%, respectively, more than offsetting gains in chemicals and industrial machinery, the data showed.

The data comes as some economists predict Asia's fourth-largest economy, which relies more on exports for growth than on domestic consumption, will fall into recession in the current quarter.
