ULAN BATOR, July 18 (Xinhua) -- Mongolia's industrial output reached 8.4 trillion Mongolian tugriks (3.12 billion U.S. dollars) in the first half of 2019, a 12.6 percent increase year-on-year, the country's national statistics office said Thursday.

It was mainly attributed to a significant increase in the output of main mining and extractive products, according to a release of the office.

Coal production increased by 35.1 percent, while the volume of iron ore production went up 2 percent against the corresponding period of 2018.

Currently, over 80 percent of Mongolia's total industrial production is accounted for by mining products. (1 U.S. dollar = 2,662.33 Mongolian tugriks)
