Vučić also pointed out that the entire world is facing an energy crisis.

“America is declaring a state of emergency over electricity.

In Switzerland, there is actually a state of emergency due to electricity,” he said.

Earlier, Russian President Vladimir Putin and Vučić agreed during a telephone conversation that Russia would continue uninterrupted gas supplies to Serbia.

According to the Serbian leader, he has reached an agreement on a "favorable" price for Russian gas supplies.
