Mongolia's industrial output rose 19.5 percent in the first 11 months this year, compared to the same period last year, official data showed Wednesday.

The industrial output amounted to 14.1 trillion Mongolian Tugriks (over 5.3 billion U.S. dollars) in the January-November period, according to the data released by the National Statistical Office.

Output of the main mining products increased by 18.3 percent year on year, which is a key engine of industrial production growth in Mongolia.

In particular, raw coal production increased by 57.9 percent, and iron ore production rose 3.3 percent year-on-year in the period.

Mining is the main industry of the landlocked Asian country. Currently, the industry accounts for about a quarter of the mineral-rich nation's gross domestic product and about 90 percent of exports.
