Putin has threatened so called unfriendly states to pay in rubles or have its gas supply shut off. It has said it doesn't buy things for free and so isn't going to charitable with its energy.
Europe has kicked against this with Germany saying its being blackmailed by this move. What other choice does Europe has with Russia alone selling about 40% of energy to the world.
This is quite interesting when everything has been estimated in advance. In my opinion, Putin had anticipated the risk of sanctions from the start, he would launch his actions on Ukrainian soil. Involving parties to show real alignments. Isn't this as if trying to filter which countries are pro and not. Then after that he imposed the payment of Rubles for the purchase of Gas and Oil. A few days ago, the gasoline shop where I live experienced a 10% increase and it was so bloated that I had to walk. Well, unfortunately, the oil and gas collectors piled it behind the house and then played the hoarding business of gas and oil.
