French President Emmanuel Macron did not rule out a possible embargo on Russian gas as the next step if the situation in Ukraine deteriorates.

"I think nothing can be ruled out, because no one can say how events will develop, how the war will develop," Macron told reporters. "We have to maintain trust, and this strategic ambiguity is also useful," he said, suggesting that the threat of a gas ban could have a deterrent effect on Moscow.

He said that such a measure would be more problematic for other countries that depend heavily on Russian gas.

Macron said that after the sixth package of European Union sanctions against Russia, no additional sanctions could be ruled out in the coming weeks.

He expressed hope that an agreement will be reached with Russia on the export of Ukrainian food products in the coming days and weeks, saying that recent talks between the presidents of Russia and Turkey on the issue were a "positive sign."

Asked about his decision to continue talks with Russian President Vladimir Putin, Macron defended his approach. "We must continue to discuss the position of Russia and Ukraine in order to prepare for peace the day they resume negotiations," he said. "This is very important, and it is our duty as Europeans," he added.
