Ukraine plans to carry out a major prisoner swap with Russia and hopes it will take place next week, Ukraine's Foreign Minister Vadym Prystaiko said late on Thursday.

The comments come after a breakthrough at talks between Moscow and Kiev this week that open the way for an international summit to be held aimed at ending the conflict between Kiev and pro-Russian rebels in Ukraine's east.

Russia and Ukraine swapped dozens of prisoners on Sept. 7 in a carefully negotiated rapprochement that was praised in the West and appeared to presage a thawing in relations that have been frozen since Moscow's annexation of Crimea in 2014.
