ISTANBUL, October 27. /TASS/. UN Special Envoy for Syria Staffan de Mistura said he held meaningful and constructive discussion with the leaders of Russia, Germany, France and Turkey at a four-way summit in Istanbul on Saturday.
He said the summit was of particular importance.
Earlier, the UN special envoy, who will step down from his position in late November, said he would brief the participants of the summit and would speak about consensus in support of UN efforts to establish a constitutional committee.
"Tomorrow, I will be traveling to Istanbul to brief the presidents of France, Germany, Russia, and Turkey when they meet to discuss Syria," De Mistura told members of the UN Security Council on Friday via a video link.
"I will use that occasion to remind these four important leaders that given that a catastrophe in Idlib has so far been avoided; given the international consensus to see a credible and balanced constitutional committee under the UN facilitation as soon as possible; and given Secretary-General’s instructions to me, who I am constantly consulting, on this occasion even more than ever, that I should be exhausting every avenue in the time that remains of my mandate - there is in my opinion still a clear window of opportunity that needs to be urgently seized," he said.
"The influence that can be exercised by all world leaders including very much the four world leaders who I am meeting tomorrow in Istanbul can be crucial in ensuring that this happens," he concluded.
