Following a call with Russian president Putin and meeting with his Ukrainian counterpart, Volodymyr Zelensky, at his Mar-a-Lago estate, President Trump said early Sunday that he made "a lot of progress" in talks with Ukraine and Russia, and that they were getting "closer" to settling the status of the disputed Donbas territory, but that it remained challenging.

"It's unresolved, but it's getting a lot closer. That's a very tough issue, but one that I think will get resolved," Trump told reporters in response to a question about the Donbas..

Asked if Putin was committed to peace despite the attacks, Trump said:

"He's very serious."

"I can say that I believe Ukraine has made some very strong attacks also, and I don't say that negatively. I think you probably have to," Trump said outside his estate.

Speaking next to Zelensky, who stood a step below him at the entrance in front of waiting cameras, Trump said that an emerging agreement would also be good for Ukraine.

"There will be a security agreement. It'll be a strong agreement," Trump said.

"And the European nations are very much involved in that. They'll be very much involved in protection, et cetera," he said.

Zelenskiy said the peace framework is "90% agreed" and that "US-Ukraine security guarantees" are "100% agreed", with the military dimension also "100% agreed".

Trump said he has offered to address Ukraine's parliament to push the latest peace plan forward, saying "I'm not sure that it would be really necessary, but if it would help save 25,000 lives a month, or whatever it may be, I would certainly be willing to do that."
