WASHINGTON, July 22, 2021 (BSS/AFP) - US President Joe Biden will welcome his Ukrainian counterpart Volodymyr Zelensky to the White House on August 30, press secretary Jen Psaki announced -- with Kiev likely to push for more support in its protracted war with Russian-backed separatists.

   Washington has long backed Kiev in the dispute with Moscow, and had initially invited Zelensky to visit in July.

   "The visit will affirm the United States' unwavering support for Ukraine's sovereignty and territorial integrity in the face of Russia's ongoing aggression in the Donbas and Crimea," Psaki said in a statement.
