Vital supplies of US liquefied natural gas are due to start flowing into war-ravaged Ukraine this winter via a pipeline across the Balkans.
The deal was announced after Ukrainian President Volodymyr Zelensky met Greek Prime Minister Kyriakos Mitsotakis in Athens on Sunday. Greece is working to increase the flow of American LNG to its terminals to replace Russian gas in the region, Mitsotakis said recently.
The European Commission plans to ban all imports of Russian gas to EU member states by the end of 2027, arguing revenue from such sales funds Russia's war in Ukraine.
Zelensky is currently in France, where he President Emmanuel Macron signed a letter of intent to buy up to 100 Rafale jets.
Fighting continued overnight, with six people reportedly killed in Russian attacks in the Kharkiv, Kherson and Donetsk regions of Ukraine. Russia's military said it had taken control of three more Ukrainian villages - one each in the Kharkiv, Donetsk and Dnipropetrovsk regions. None of the reports could be independently verified.
Speaking earlier in Athens, Zelensky was quoted as saying that deliveries of US LNG would begin in January.
We rebuild each time the Russians destroy but this truly requires time, much effort, equipment and, regarding gas... imports to compensate for the destruction by the Russians of our own production, he said.
Greece is becoming an energy security provider for your homeland, Mitsotakis told the Ukrainian president.
Zelensky said Kyiv had allocated funds for gas imports from European partners and banks under European Commission guarantees, as well as from Ukrainian banks, to help cover imports through to March at a cost of nearly €2bn (£1.8bn; $2.3bn), according to news agency Reuters.
Since 2015, when it stopped buying Russian gas directly, Ukraine has been receiving supplies from various EU states. The Soviet-era Trans-Balkan pipeline links Ukraine to LNG terminals in Greece via Moldova, Romania and Bulgaria.
There have been fears of an energy crisis in Ukraine this winter after sustained Russian attacks on its energy facilities, notably thermal power plants.
The UN Office for the Co-ordination of Humanitarian Affairs has issued a formal warning, saying the approaching winter poses new risks for Ukrainians... as intensified attacks on energy networks undermine efforts to maintain warmth in homes, schools and health centres.
