American President Joe Biden wants to exchange views on the Ukraine conflict with Chancellor Olaf Scholz (SPD) and other allies this Friday.
EU Commission President Ursula von der Leyen, EU Council President Charles Michel, NATO Secretary General Jens Stoltenberg, France's Head of State Emmanuel Macron, British Prime Minister Boris Johnson, Poland's President Andrzej Duda, Romanian President Klaus Iohannis, Italy's Prime Minister Mario Draghi and Canada's Prime Minister Justin Trudeau are in attendance, the White House said.
The talks will focus on "common concerns about Russia's continued military build-up" on the Ukrainian border.
The aim is to continue to exchange views on the "coordination of diplomacy and deterrence".
Blinking: Invasion could begin at any time
US Secretary of State Antony Blinken said earlier that he believed Russia could invade Ukraine during the Beijing Olympics.
"We are in a window where an invasion could begin at any time," Blinken said at a news conference in Melbourne on Friday.
The US observed worrying signs of a Russian escalation, including fresh troop deployments on the border.
Biden urged American citizens to leave the country on Thursday.
If there were to be a Russian invasion, an evacuation mission using US troops would be unthinkable, Biden said in an interview.
During a visit to Romania on Friday, NATO Secretary General Jens Stoltenberg said he expects the alliance's defense ministers to issue a planning order next week for the stationing of a battlegroup in Romania and possibly in other countries in south-eastern Europe.
The Americans are currently moving a thousand soldiers with Stryker wheeled armored vehicles from Germany to Romania.
No progress in Normandy format
Foreign Minister Annalena Baerbock (Greens) sees “no signs of de-escalation” in the Ukraine crisis, at least militarily.
"The situation is incredibly tense," said Baerbock on a visit to Jordan on Friday.
After a round of talks in Berlin, the chief negotiators of Germany, France, Russia and Ukraine said that no progress had been made towards a peace solution for eastern Ukraine;
However, it had become clear that all participants in the so-called Normandy format would continue to adhere to the existing agreements for a solution and wanted to implement them.
Meanwhile, a meeting between German company heads and Russian President Vladimir Putin planned for early March has been met with criticism.
Deputy FDP parliamentary group leader Lukas Köhler told the FAZ that in view of Russia's "blatant threats against Ukraine" it would have been a "appropriate signal to Putin to cancel this year's meeting and not to offer the Russian president a high-level platform of the kind that he usually knows how to use them for his propaganda purposes".
