Reading out the points of the call, the White House underscored the commitment of the United States to Ukraine's sovereignty and territorial integrity. Both discussed coordinated diplomatic efforts on European security stressing on the principle of nothing about Ukraine without Ukraine, the White House said.


In his conversation, Biden put forth the US' support for conflict resolution efforts in the Normandy Format, showing hope that the recommitment this month to the terms of the July 2020 ceasefire will help to diffuse tensions and promote the implementation of the Minsk Agreements.


Meanwhile, White House Press Secretary Jen Psaki informed that the US has seen preparations and buildup at the border and that an invasion could come at any time. Our assessment has not changed since that point, she added.


A day earlier, the United States and NATO both separately delivered their responses to Russia, which a senior State Department official said they believe that these responses offer a real opportunity for security improvements across the Euro-Atlantic area if Moscow chooses the path of diplomacy rather than that of conflict or sabotage.
