Petro Poroshenko's announcement comes after a phone conversation he had with the Russian president, Vladimir Putin
The Ukrainian president, Petro Poroshenko, said he would order a ceasefire to begin at lunchtime on Friday if peace talks that are planned to be held in Minsk, Belarus, are confirmed.
Speaking on the sidelines of a Nato summit in Wales, Poroshenko said: "At 2pm local time [11am GMT] on Friday, provided the [Minsk] meeting takes place, I will call on the general staff to set up a bilateral ceasefire and we hope that the implementation of the peace plan will begin tomorrow."
The announcement comes after a phone conversation between Poroshenko and Vladimir Putin on Wednesday. The Russian president later released a seven-point "peace plan" for eastern Ukraine.
