"Much of the debate in Washington has been focused on whether we should provide additional defensive lethal weapons to Ukraine," Biden said at the Brookings Institution in Washington on May 27.
According to him, this debate still continues.
He stressed that as long as "Ukraine leaders keep faith with the project of reform, the United States will continue to stand with them."
"In total we've provided our $470 million in economic assistance to sort out the crisis," he said.
"In addition, [there was] a one billion dollar loan guarantee last year, another one billion loan guarantee [was] signed this month, and potentially [there could be] further one billion dollars at the end of this year if Ukraine continues on the path of reform," he said.
"And that $470 million includes nearly $200 million to the armed forces, National Guard and border services," he said.
"Let's not lose sight of the fact – Ukraine also needs basic military equipment and training, which we're also providing on the ground," he added.
