The United Nations Special Envoy for Syria, Staffan de Mistura, just annouced that the next round of intra-Syrian talks will take place in Vienna, Austria, January 25 and 26. According to the statement the meeting will focus on constitutional issues.
Staffan de Mistura "expects that delegations will be coming to Vienna prepared for substantive engagement with him and his team with a specific focus on the constitutional basket of the agenda towards the full implementation of Security Council resolution 2254 (2015), and bearing in mind the parameters and observations he laid out in his briefing to the Security Council on 19 December 2017."
The message reiterated the view of the United Nations "that any political initiative by international actors should be assessed by its ability to contribute to and support the United Nations-facilitated Geneva political process and the full implementation of resolution 2254 (2015)."
The choice of the International Vienna Centre is due to "logistical reasons".
