Western powers have called on Russia to lower tensions with Ukraine, and backed Kyiv against any threats from Moscow.
US President Joe Biden spoke with UK Prime Minister Boris Johnson, and the leaders of France, Germany and Italy, agreeing to use “all the tools at their disposal” to prevent aggression.
Mr Biden is to speak to Russia’s President Vladimir Putin by video call later on Tuesday.
Russia has boosted its troops near Ukraine’s border, prompting fears.
But Moscow says it has no plan to attack Ukraine and has accused Western nations of provocation.
In a conference call on Monday night, the Western leaders discussed their “shared concern about the Russian military build-up”, according to the White House.
