President Trump and Russian strongman Vladimir Putin are both on the ground in Alaska for a high-stakes summit -- the powerful world leaders just greeted each other on the tarmac ... and it's all on video.

Trump and Putin shook hands Friday after flying into Joint Base Elmendorf-Richardson in Anchorage ... emerging from their planes after waiting around on their aircraft for a good while after landing.

They each walked down a red carpet and Trump waited for Putin and then they shook hands and patted each other on the shoulder, exchanging a few words on their way over to a blue stage adorned with "ALASKA 2025."

POTUS has deemed this a "high-stakes" meeting and he's expected to talk with Putin about a potential ceasefire in the Russia-Ukraine war. Gallery Launch Gallery Getty
