Price of most common used A92 type of petroleum has been increased up to 1300 MNT per liter from last Sunday. The price rise already started to affect the price of consumer goods. Frustrations started to grow as the price of petroleum increased three times in a month without prior notice. Petroleum importers explain that ‘unavoidable’ increase was caused by the export tax of Russia and Rosneft, Russian oil supplier. Mongolia imports most of its petroleum directly from Rosneft.
