The United States and France have both reaffirmed support for Ukraine in its battle against Russia’s invasion during a meeting in the French capital.

Speaking at a joint news conference at the Presidential Elysee Palace in Paris on Saturday, President Joe Biden warned that Vladimir Putin would “not stop” at Ukraine. French President Emmanuel Macron, in turn, hailed his US counterpart’s loyalty to Europe.

“All of Europe will be threatened, we are not going to let that happen,” Biden said during his state visit to France. “The United States is standing strong with Ukraine. We will not, I say it again, walk away.”

Macron then told Biden in front of reporters: “I thank you, Mr President, for being the president of the world’s number one power but doing it with the loyalty of a partner who likes and respects the Europeans.”

The US president has been in France since Wednesday, taking part in commemorations marking the 80th anniversary of the D-Day landings that changed the course of World War II.

On Friday, both Biden and Macron met Ukrainian President Volodymyr Zelenskyy in Paris, pledging support for Ukraine.

In a statement released by the White House on Saturday, the French and US leaders said they agreed that wider security across the Atlantic was at stake in Russia’s war.

“France and the United States co-chair the artillery coalition at the Ukraine Defense Contact Group and intend to take new steps to provide the necessary support to Ukraine in the current phase and in the longer term,” the statement said, referring to a coalition of about 50 countries that meet regularly to discuss Ukraine’s security needs.

The US and France also reaffirmed their commitments to the “continued provision of political, security, humanitarian, and economic assistance to Ukraine”, the statement said.
