Gazprom has stopped supplying natural gas to six European countries. What will the EU do? How much will the budget lose?

It won't affect for a long time, because the gas transmission equipment in any direction in Russia is a product of Siemens in Germany.

Within half a month, Russia offered to resume gas supply.
