Washington promised Kyiv up to $60 million in military aid before U.S. President Joe Biden and his visiting Ukrainian counterpart, Volodymyr Zelenskyy, met in the White House on September 1.

The Biden Administration said in a notification to Congress cited by the AP news agency on August 31 that the aid package for Ukraine was necessary because of a “major increase in Russian military activity along its border” and because of mortar attacks, cease-fire violations and other provocations.
