The meeting comes as Russia has redoubled its efforts to take over Ukraine following a brief respite as it repositioned forces earlier in April.

Biden approved an $800 million military aid package for Ukraine, supplying the country with weapons critical to its defense effort.

"This new package of assistance will contain many of the highly effective weapons systems we have already provided and new capabilities tailored to the wider assault we expect Russia to launch in eastern Ukraine," Biden said in a statement.
