"We stand shoulder to shoulder when it comes to preservation of our democracies," Zelenskiy wrote on Twitter. "The American partnership is crucial for Ukrainians."
"President Biden affirmed the United States' unwavering support for Ukraine's sovereignty and territorial integrity in the face of Russia's ongoing aggression in the Donbass and Crimea," the statement said.
"The leaders agreed these reforms are central to Ukraine's Euro-Atlantic aspirations," the statement said.
