Idlib to take center stage in Turkey, Russia, Iran talks

The presidents of Turkey, Iran and Russia are meeting in Ankara on Monday to discuss Syria and the last rebel enclave in Idlib amid Turkish concerns over the consequences of a Syrian government offensive there. Turkish President Recep Tayyip Erdogan is expected to seek an elusive longer-term solution to the issue with his Russian and Iranian counterparts, Vladimir Putin and Hassan Rouhani.

Deutsche Welle reports in its article Syria's Idlib to take center stage in Turkey, Russia, Iran talks that the three countries support opposing sides in the conflict but have come together under the so-called Astana process to find a political solution to end the Syrian war.

Why are they meeting?

Syrian government forces, backed by allied paramilitary groups and Russian airpower, launched an offensive in late April against rebel and jihadi factions led by Hayat Tahrir al-Sham (HTS) in northwestern Idlib province, as well as parts of the neighboring provinces of Aleppo, Hama and Latakia. After the offensive initially stalled, the past few weeks have seen Syrian forces advance into jihadi-controlled areas in southern Idlib following heavy bombardment that has sent hundreds of thousands of the enclave's 3 million civilians fleeing to the border with Turkey. Ankara is concerned that the regime offensive could send a flood of refugees and hardened extremist fighters to Turkey, which already hosts more than 3.5 million refugees.

What has been the result of the previous deal?

The fierce fighting in Idlib has all but unraveled a fragile truce deal struck in September last year between Russia and Turkey. The deal envisioned the creation of a demilitarized buffer zone between regime- and rebel-controlled areas and an as-yet-unfulfilled commitment by Turkey to isolate and combat jihadi groups. Turkey also established a dozen military observation posts along the perimeter of Idlib, one of which was surrounded by regime forces last month. There have been occasional clashes between the Turkish military and Syrian regime-aligned forces.

What's restraining the warring sides?

The situation in Idlib is driven by the interests of competing and cooperating foreign powers on the ground — namely Turkey, Russia and Iran — all of which have varying degrees of leverage to put the brakes on the Assad regime's goal of recapturing lost territory at any cost. Turkey seeks to capitalize on its budding relationship with Russia as well its historically friendly relationship with Iran to hinder conflict in Idlib in order to pave the way for a broader political solution to the Syrian civil war. Russia needs to balance its support for the Syrian regime's goals in Idlib with its larger geostrategic interests of developing blossoming political and military ties with Turkey, which has NATO's second-largest army. However, it wants Turkey to do more to control jihadi factions led by HTS. If Russia were to go too far in supporting Syria in Idlib, it could severely damage relations with Turkey and provoke a clash between Damascus and Ankara.

Possible scenarios

A Syrian regime drive deeper into Idlib and onto the border would likely trigger a robust response from the Turkish military and its rebel allies to avoid a worst-case scenario of refugees and hardened jihadi fighters pouring across the border. One possible scenario to address the situation would be a mixed formula whereby Turkey would control a safe zone along its border with Idlib, while Syrian forces take control of the southern parts of the province, including the strategic highways. That would still leave the safe zone largely in the hands of jihadis — who increasingly feel sold out by Turkey to the Russians — unless Turkish forces and allied rebels were to move against them. Turkey has been hesitant to take on HTS militants for fear of creating a humanitarian disaster. The jihadis have generally maintained friendly relations with Turkey because Ankara maintains significant leverage over the border that provides a lifeline to armed groups and civilians. For Ankara, such a band-aid solution would add to buffer zones established in Afrin and northern Aleppo in previous military interventions, and allow Turkey to focus on northeastern Syria, where it seeks to create a buffer zone with the United States to address its concerns over the Syrian Kurds. Turkey intends to use the buffer zones to send at least 1 million Syrian refugees back to safe areas.
