"NEUTRAL"(just a joke as I will not forget money exchange game in Minsk where I lended in 2017 - Ukrainian money was everything but financial currency in Belarus already back then) in conflict(there is no conflict here, but instead repeated for century long Russian aggression on weaker neighbor) Belaus sells stolen coal from Russian-occupied Ukrainian Donbas area back to Ukraine.

Coal from Russian-occupied areas of the Donbas, which is at war with Ukraine, may be passing through Belarus and being sold back to Ukraine, according to reports analyzing Belarusian government statistics.

Belarusian coal exports to Ukraine jumped by hundreds of percentage points in 2018 compared to 2017 across almost most categories, according to the National Statistical Committee of Belarus,The total mass of rock coal exports to Ukraine rose by 946 percent to more than a half-million tons. The dollar value of these exports rose by 798 percent, to $50.3 million. Belarusian exports of anthracite, the highest grade of coal, to Ukraine, rose by 307 percent to $8.8 million.

There appears to be no other likely source other than Russian-controlled Donbas. Ukrainian veterans at one time mounted a vigorous blockade on direct trade between Russian-occupied Donbas and Ukraine, perhaps prompting the need for more circuitous route. The Kyiv Post in 2017 extensively covered the blockade efforts in this story and in this photo gallery. The issue is a highly emotional one, with some favoring a complete ban on trade with the Russian-occupied areas, condemning it as “blood money” considering the 13,000 Ukrainians killed by Russia’s war. Others say that those supplying the needed coal are Ukrainians, too, in need of jobs and money.
