Let me give you a flavor:
According to the source of the newspaper, Rosneft proposes to switch the supplies of Russian natural gas to Europe to payment in advance mode. Officials with the oil company believe that such a move would improve Gazprom‘s economy to the detriment of European buyers of the Russian gas.
Personally, I think that this article is designed to throw red meat to the Russian masses who are looking to a hard winter on the back of international sanctions.
Retaliatory sanctions from Russia would seriously escalate the current crisis. Perhaps, it’s a bluff to bring concessions from the West? It’s hard to imagine Europe’s banks being able to finance payment in advance for Russia’s gas?
