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 has been 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 that revenue from such sales funds Russia's war in Ukraine.
Zelensky is now in France for talks with President Emmanuel Macron over a major deal on air defence hardware.
Fighting continued overnight, with six people reported killed in Russian attacks in the Kharkiv, Kherson and Donetsk regions of Ukraine.
