The presidents of Turkey, Iran and Russia held a virtual summit to discuss the latest developments in Syria today.

Recep Tayyip Erdogan, Hassan Rouhani and Vladimir Putin convened under the so-called Astana format that’s seen the three regional powers make accommodations while pursuing conflicting agendas in Syria. Turkey backs anti-government Sunni rebels while Iran and Russia are propping up the government of Syrian President Bashar al-Assad.

Why it matters:  It was the three leaders' first such meeting since Turkey butted heads with Russia and Iran in the rebel held-province of Idlib in March. At least 33 Turkish soldiers perished in a February airstrike thought to be carried out by Russian air force jets. Turkey retaliated against Syrian regime forces and Iran-backed Shiite militias, earning plaudits from the United States. But a cease-fire for Idlib struck in Moscow in March between Erdogan and Putin was largely on the latter’s terms.

US President Donald Trump’s envoy for Syria engagement, Ambassador Jim Jeffrey, who cheered Turkey on against the Russians in Idlib, will have been miffed by the joint statement put out by the trio that laid rest to speculation that the Astana process was dead. It contained thinly veiled pot shots at the United States with its reference to the “illegal seizure and transfer of oil revenues that should belong to the Syrian Arab Republic.” Trump said that US forces are staying on in the Kurdish-run northeast to “secure” two major oilfields there that contain most of the country’s oil. In a swipe at the Syrian Kurds, the statement said the leaders “rejected illegal self-rule initiatives.”
