New York – UN envoy for Syria, Staffan de Mistura, will join Syrian high-level talks on enforcing ceasefire in Kazakhstan this week, a UN statement said Monday.

The statement added that in view of the urgency and importance of re-establishing a de-escalation of the situation in Syria and moving on confidence-building measures, de Mistura has agreed to attend the meeting as an observer at the invitation of the Kazakh government.

The 4th international conference on Syria will take place in Astana, Kazakhstan’s capital, on May 3 and 4. Experts are due to hold bilateral consultations on Tuesday.

While in Astana, de Mistura is planning to conduct political consultations with the ceasefire guarantors and other participants on military situations.

“This will be particularly timely as he’s currently putting finishing touches on his deliberations regarding the next round of intra-Syrian talks in Geneva,” the statement declared.

The previous conference on Syria was held in Astana on March 14-15. Delegations of Russia, Iran and Turkey, which had brokered a nationwide ceasefire in Syria, took part in the negotiations alongside the Syrian government delegation and experts from the UN, United States and Jordan.
