But Trump, in announcing the meeting, was noncommittal about any coming American security guarantees.
"I'm not going to make security guarantees ... very much," Trump said. "We're going to have Europe do that."
He said a U.S. presence working on mineral extraction would amount to "automatic security because nobody's going to be messing around with our people when we're there."
"It's a great deal for Ukraine too, because they get us over there and we're going to be working over there," Trump said. "We will be on the land."
Since returning to office last month, Trump let Ukraine know that he wanted something in return for tens of billions of dollars in U.S. help for Ukraine. The White House has applied heavy pressure on Ukraine to grant American access to its vast reserves of the minerals.
