And how does one export when every country is rejecting your ships and planes?
It's only the moron Germans who have emboldened this dependency on russian gas. I bet cuadrilla are buzzing if they haven't totally shut shop.
Not only that - payment would have to be made through non-banking means. They'd have to withdraw the money first then send it back to be deposited in a separate location unless it's through China.
Yes, the Russians have been diversifying and buying gold and metals to 1/3 to stop a complete failure. If all the companies fail in russia then Putin will have his state owned oligarch-ridden companies operating - so back to a imperial/communistic commercial model.
For gas, liquified gas is something that the US wanted to provide EU with. Naturally more difficult with submarines like sharks.
