"The russians said something privately, something they said publicly; nothing will distract us from the strategy we have started," he said.
The State Department spokesman also added: "If the Kremlin accuses the United States and our partners around the world of providing billions of dollars in security assistance to our Ukrainian partners, of providing exactly what our Ukrainian partners have asked for and what our Ukrainian partners are using extreme effectively fighting off russian aggression, well, then we are guilty of what we are accused of".
The Kremlin "should not be surprised" by US support for Ukraine, given the Biden administration's commitments to support Ukraine before the russian invasion began, Ned Price added.
This week russia sent a diplomatic note to the United States with a "warning" regarding assistance of Ukraine with weapons. The russians said it was "adding fuel to the fire" and could have unpredictable consequences "for regional and international security."
On April 14, President Joe Biden announced that the United States will transfer to Ukraine artillery systems, shells, armored personnel carriers and helicopters to counter russian aggression.
Subsequently, the Pentagon revealed the content of a new aid package to Ukraine: 18 howitzers, 200 armored personnel carriers, 500 Javelin missiles, 300 kamikaze drones.
