Ukrainian President Petro Poroshenko promised after late-night negotiations with Russia's Vladimir Putin to work on an urgent cease-fire plan to defuse the separatist conflict in the east of his former Soviet republic.
The first talks between the two leaders since June were described by Putin as positive, but he said it was not for Russia to get into the details of truce terms between the Kiev government and two rebel eastern regions.
"We didn't substantively discuss that, and we, Russia, can't substantively discuss conditions of a cease-fire, of agreements between Kiev, Donetsk and Luhansk. That's not our business, it's up to Ukraine itself," he told reporters early on Wednesday. "We can only contribute to create a situation of trust for a possible, and in my view, extremely necessary, negotiation process."
