A Ukrainian official told CNN’s Matthew Chance that he is “shocked that the US President Biden would distinguish between incursion and invasion” and suggest that a minor incursion would not trigger sanctions but an invasion would.

“This gives the green light to Putin to enter Ukraine at his pleasure,” the official added.

The Ukrainian official said he’d never heard any nuance like this from the US administration before.

“Kyiv is stunned,” he added, referring to the Ukrainian government.
