After an unprecedented exchange of US intelligence with the EU and NATO, the allies have swung behind Joe Biden's assessment that Russia is prepared to invade Ukraine.
Mr Biden will warn against an invasion in an upcoming video summit with Mr Putin.
The US President will have full backing from NATO and the EU for retaliatory measures, according to the Financial Times.
A Biden administration official warned that Russia may be planning an invasion of Ukraine as soon as early 2022, and half of the military units that would be necessary for an offensive of that nature had arrived near Ukraine's border over the past month.
Washington hopes that by establishing strong western support for sanctions, it would drive home the costs of any aggression to Moscow.
Four of the European allies who spoke to the Financial Times said that the Russians were preparing for an invasion because of an initial reluctance from some European allies to believe that Russia was prepared for an invasion.
