The next round of talks to end Russia's four-year invasion of Ukraine are expected to be held in early March in Abu Dhabi, Ukrainian President Volodymyr Zelenskyy said on Thursday after his officials concluded a meeting with U.S. envoys in Geneva.

Previous rounds of U.S.-led negotiations between Russian and Ukrainian officials in Geneva and Abu Dhabi have failed to yield a compromise, including on the key sticking point of territory.

"As a result of today's meetings, there is already more readiness for the next trilateral format," said Zelenskyy, adding that the meeting would "most likely" take place in Abu Dhabi in early March.

"We need to finalize everything that has been achieved in terms of real security guarantees and prepare for a meeting at the leadership level," he said in a regular evening address.

"This format can solve a lot," Zelenskyy added, referring to a potential meeting with his arch-foe, Russian President Vladimir Putin.
