"By winter, we want to completely end the war," he said in an interview with the Azerbaijani news agency Report.
At the same time, according to him, Kiev's plan is to return Ukraine to the 1991 borders.
He added that in order to achieve this goal, Kiev will not be limited by time, but will "fight as long as it takes."
Ukrainian President Volodymyr Zelensky also said that Kyiv would not make territorial compromises to achieve peace.
He noted that, according to Kiev, the territorial integrity of Ukraine should be restored within the borders of 1991.
Russian Foreign Minister Sergei Lavrov said that negotiations on a settlement in Ukraine can only be held on the basis of taking into account Russian interests.
