Russia, Turkey and Iran, which support opposing sides in Syrias war, agreed Wednesday to coordinate their efforts to reduce tensions in the country, whose conflict has entered its 10th year. The three "reiterated their determination to enhance the trilateral coordination", said a joint statement issued at the end of a video conference between their leaders. The declaration also "emphasized their strong commitment to the sovereignty, independence, unity and territorial integrity" of Syria. The talks were the first since September in the so-called Astana format, talks between the three main foreign powers in the Syrian conflict. Iran and Russia have been staunch supporters of Bashar Assad’s regime, while Turkey has called for its ouster and backed opposition armed groups. The conference comes at a time when Russia-Turkey relations are tense not just over Syria but also Libya, another theater of war where Moscow and Ankara support opposing fighters. But Irans Foreign Minister Mohammad Javad Zarif, whose country chaired the online meeting, described the talks as "constructive". Irans President Hassan Rouhani told the conference his country believes “the only solution to the Syrian crisis is political and not a military solution." "We continue to support the inter-Syrian dialogue and underline our determination to fight the terrorism of ISIS, al-Qaeda and other related groups," he said. "I emphasize that the fight against terrorism will continue until it is completely eradicated in Syria and the region in general." Putin raised similar concerns. He said the objective of the conference was to analyze the situation and agree on steps "to ensure the long-term normalization in Syria". "Above all, it is a question of continuing the fight against international terrorism," he said. "The most tense situation is still being observed in territories outside the control of the Syrian army, particularly in the de-escalation zone of Idlib and in northeastern Syria". "We need to actively help advance an inclusive inter-Syrian dialogue," said the Russian leader. Sanctions to suffocate Syria Idlib is held by extremist and opposition groups, some of them backed by Turkey, which has deployed forces in several military posts in the region as part of a 2018 deal with Russia. Putin also denounced as "illegitimate" a new raft of US sanctions against Syria. He stressed "the negative impact of the sanctions put in place against Syria, bypassing the UN Security Council". The Caesar Act, which took effect in mid-June, punishes under US law any company that works with Assad. The measures have cast a cloud over efforts to rebuild the war-ravaged country. "Despite the call from the UN Secretary-General for easing the pressure of sanctions under pandemic conditions, Washington like Brussels decided to prolong measures against Syria," Putin told the conference. "In addition, new sanctions presumably aimed at economically suffocating Syria have been adopted." Turkish President Recep Tayyip Erdogan said Ankara’s "fundamental priorities are to safeguard Syrias political unity and territorial integrity, restore peace on the ground and find a lasting political solution to the conflict." "We will continue to do what we can to restore peace and security to our neighbor Syria as soon as possible," he stated. After delivering their opening statements, the three presidents were to discuss Syria in private. As well as Idlib, Turkey also controls a stretch of territory along its border in neighboring Aleppo province following a series of military offensives since 2016. The conflict in Syria has killed more than 380,000 people and displaced millions.
