Ukraine hopes for more significant support from the United States in the event of the escalation of Russian aggression against Ukraine, Ukrainian First Deputy Prime Minister Vitaliy Yarema has said.

"We hope that in the case of Russian aggression, the United States will not leave us to stand alone. At least we hope that their help will be more significant. We enlisted the support of the United States so that they won't leave us one-on-one with the aggressor," he told reporters in Kyiv on Wednesday.
