The move by the outgoing Biden administration comes amid concerns about the level of support the Trump White House may want to give Ukraine.

Mr Trump has previously vowed to limit US support for Ukraine and end its war with Russia.

But the attacks are not carried out with words. Such missiles will not speak for themselves.”

In September, Russian President Vladimir Putin said that if the United States lifted the ban on the use of long-range missiles, it would be seen as NATO’s “direct participation” in the war.

He added: “This will of course significantly change the essence and nature of the conflict.”

Speaking to reporters on his way to the summit, he added: “On Tuesday we come to the 1,000th day of this conflict.

“This means 1,000 days of Russian aggression, 1,000 days of massive impact and sacrifice to the Ukrainian people, and recently we have seen North Korean troops working with the Russians, and this has serious consequences.

“On the one hand, I think this shows Russia’s desperation, but this has serious consequences for European security (…) and Indo-Pacific security, and that’s why I think we need to double down on increasing our support for Ukraine. This is the most important issue on my G20 agenda .

“There has to be full support, no matter how long it takes, and that’s absolutely at the top of my agenda and supporting more support for Ukraine.”
