Ukrainian president highlights 'significant progress' in talks, but Moscow says Kyiv is working to 'torpedo' deal.

Kyiv has been pressing Washington to modify a peace plan that, in a draft unveiled last month, echoed Moscow's main demands.

President says negotiators secured gains on issues like army numbers, but control of Donbas 'most difficult point'.

“A lot can be decided before the New Year,” Zelenskyy said.
