Trump said Sunday, that both Ukraine and Russia had agreed to the ceasefire.
Moscow remains tight-lipped about a potential halt to attacks on energy infrastructure in Ukraine.
Speaking to TASS, Kremlin spokesman Dmitry Peskov confirmed that discussions are happening, though he gave little away.
“Contacts are ongoing. As soon as we have anything to say on this topic, we will definitely inform you,” Peskov noted.
He refused to clarify if a prospective “energy truce” would focus solely on oil refineries. Nor would he name the specific parties taking part in the dialogue.
On Sunday, US President Donald Trump announced that Russia and Ukraine had already reached an “energy ceasefire.”

“Truce” already broken
Shortly after Donald Trump announced the alleged ceasefire, Ukraine accussed Russia of targeting a thermal power plant in Kharkiv.
“There were Russian violations of the energy ceasefire announced by President Trump,” Zelenskiy told a conference in Warsaw via video link according to Reuters.
Zelensky made it clear, that even though Ukraine had not targeted Russian refineries overnight, Russia must honor an energy ceasefire, if the Kremlin wants Ukraine to halt attacks on Russian energy infrastructure.
Trump faces heavy backlash
Trump’s supply deal on Russian diesel is facing heavy backlash in the US, with both Republican and Democratic lawmakers calling on the president to reverse the deal.
Reuters reports that four Republican senators and three Democratic senators have issued a joint statement, arguing the diesel deal is against US law, as Congress was not consulted (which is required by law) and that the deal violates a 2022 ban on Russian energy imports.
“The United States should not provide Putin with a financial lifeline while Russia continues to kill Ukrainian civilians. The Administration must immediately reverse course,” the statement said.
