The Russian government was forced to raise the export tax, as some manufacturers did not want to sell their products inside Russia. It was more profitable for them to sell for export, they sold at a higher price.
As a result, there was a deficit in the country and an increase in prices in the domestic market.

All this is due to the greed of the producers, not because of the economic problem in Russia!

But, naturally, everyone must now cooperate to get out of this difficult situation created by the coronavirus with less losses.
