The Kremlin has said that London's sanctions of Moscow's Gazprombank, through which payments are to be made under Russian President Vladimir Putin's rubles-for-gas scheme, mean that Great Britain won't be able to buy Russian gas.
The Epoch Times has reached out to the British Foreign and Commonwealth Office with a request for comment.
"Putin should be under no illusions—we are united with our allies and will keep tightening the screw on the Russian economy to help ensure he fails in Ukraine," Truss said on March 24.
Gazprombank has been a key channel for payments for Russian energy, made all the more critical due to Putin's rubles-for-gas scheme.
Peskov's remarks eased fears that Russia might immediately cut off energy supplies to any buyer that did not pay in rubles.

Multiple European buyers of Russian energy have so far refused to pay in the Russian currency, saying that Putin's rubles-for-gas demand breaches existing contracts.
Governments in Europe, which relies on Russia for more than a third of its gas, are in discussions with their energy companies about how to settle the transactions and are looking to come up with a common approach.
Russia says it's engaged in a "special military operation" to disarm its neighbor and topple its government, which it describes as "neo-Nazis."
Putin has said Russia's military actions in Ukraine were also motivated by what he described as "genocide" against ethnic Russians living in Donbass, the location of the separatist-controlled so-called "people's republics" of Donetsk and Luhansk.
“This rhetoric is factually wrong, morally repugnant, and deeply offensive to the memory of millions of victims of Nazism and those who courageously fought against it, including Russian and Ukrainian soldiers of the Red Army,” the scholars wrote.
Ukraine and its Western allies describe the Kremlin's actions as an unprovoked, unjustified, and illegal war of aggression.
The conflict has driven millions from their homes and killed thousands, according to the United Nations.
