The date of the next meeting of the Contact Group on Ukraine has yet to be set and it is unclear whether representatives from the self-proclaimed Donetsk and Luhansk People's Republics will attend, Ukrainian Foreign Minister spokesman Yevhen Perebyinis said.

"We are expecting a confirmation from the DPR and LPR representatives of their readiness to attend the session," he said at a briefing on Wednesday.

He did not tell the date of the meeting, saying only that Ukraine hopes it takes place as soon as possible, "before the end of this week." As regards the venue, Minsk and a video conference are being considered as 'traditional' options.
