LONDON — Ukrainians are starting to feel “abandoned,” Ukraine’s ambassador to the U.K. told CNBC on Monday, as tensions with Russia escalate and many nations urge their citizens to leave the country.

Vadym Parystaiko (Ukraine’s Ambassador to the U.K.), stated Monday that “the problem is that Ukrainians have been pushed to panic.”

Investors have withdrawn money from the airlines, and they are now cancelling flights. He said that Ukrainians felt abandoned in London.

“[We are]There is no family or friend who could help us, and we don’t have the resources to do so,” the ambassador said.

Earlier on Monday, Prystaiko rowed back on comments from Sunday where he said Ukraine could be flexible” on its ambition to join NATO — a key demand from the Kremlin. CNBC confirmed that Prystaiko still believes in this country’s potential.

The Ukraine has been seeking bilateral agreements in order to be more supportive of Russia’s aggression. We’re open to other arrangements, such as bilateral. [ones]He said,
