The US will respond "decisively" if Russia invades, President Joe Biden told the Ukrainian President.
The principle of 'nothing about you without you' was underscored by President Biden. The White House said that he affirmed the United States' commitment to Ukraine's sovereignty and territorial integrity.
The principle of 'nothing about you without you,' refers to the idea that no policy decisions would be taken without the representation of the Ukrainians. The statement said that the US and its allies support diplomatic efforts including bilateral dialogue through NATO and the Organization for Security and Cooperation in Europe next week.
On Sunday, Democratic Rep. Adam Schiff said that economic sanctions against Russia may be the best way to deter them from invading Ukraine.
Russian President Putin warned Biden last week that US sanctions could lead to a complete breakdown of ties.
Biden warned that the US would step in if Russia invaded if he asked Putin to ease tensions with Ukraine.
