epa09916750 Exterior view of the Gazprom building in St. Petersburg, Russia, 29 April 2022. Gazprom has completely suspended gas supplies to the Bulgarian company Bulgargaz and the Polish PGNiG. The reason is due to their failure to pay in rubles in due time, it is said in a statement of the Russian holding. On 23 March, Russian President Putin ordered that so-called “unfriendly” states had to pay in rubles for Russian gas, saying that Moscow would refuse to accept payments under gas contracts with those states in ‘compromised’ currencies, particularly meaning dollars and euros.
