Trump says post-war Ukraine will have a 'different shape' ahead of Abu Dhabi talks

US President Donald Trump suggested that Ukraine's territory could change as part of a future agreement with Russia, days before US-mediated talks between Kyiv and Moscow in Abu Dhabi.

"I think we're going to have it done and I think it's going to happen, and they're going to end up with a little bit different shape (for) Ukraine," Trump told CBS's "60 Minutes" in an interview published on Monday.

His remarks come ahead of trilateral negotiations involving Ukraine, Russia and the US, scheduled for 10–11 November in Abu Dhabi, the UAE.

Trump expressed confidence that an agreement was within reach, although Kyiv and Moscow remain deeply divided over territorial concessions and the security arrangements that would follow any ceasefire.

"There's a very important meeting taking place," Trump said. "I believe that that war is going to end and it's going to end soon. And the only reason it's going to end is because of me."

The US president did not elaborate on what he meant by Ukraine having a different shape or specify which territorial changes he envisaged.

US Secretary of State Marco Rubio said on Sunday that progress had been made in discussions over post-war security arrangements for Ukraine and Europe, suggesting that further advances could follow this week's negotiations.
