SOCHI, February 14./TASS/. Russia, Iran and Turkey have agreed to take additional steps towards stabilization of the situation in Syria’s Idlib, President Vladimir Putin said after the Russia-Iran-Turkey summit in Sochi.

He said that at the three-way talks, they had discussed ways to implement the Russian-Turkish memorandum on a de-escalation zone in Idlib.

"Let me note that the Iranian and Turkish colleagues are ready to work as a team with an aim of finally defusing tensions and stabilizing Idlib. We have agreed to take additional steps in this respect," Putin said.

According to Putin, the parties assume that "maintaining the ceasefire should not go to the disadvantage of efforts to fight terrorism". "Creating the Idlib de-escalation zone is a temporary measure. Aggressive sorties of militants must not go unpunished," he stressed.

The presidents also looked at the summit into advancing the political process in Syria. "We have agreed to jointly contribute to an early launch of the constitutional committee that is aimed at dealing with essential aspects of the future state structure of the Syrian republic," Putin said.

He reiterated that that most candidates for the committee have been coordinated with the Syrian government and the opposition, and "now it is necessary to approve the lineup of the committee and work out recommendations on key parameters of its functioning".

The efforts of Moscow, Ankara and Tehran have resulted in a ceasefire that is being respected almost throughout Syria, the Russian leader said.

"These meetings have facilitated progress in improving the situation in Syria. A ceasefire is in place almost throughout the entire country, which means that the level of violence has declined. It is a specific joint measure and undoubtedly a positive result," Putin said.

According to him, the Astana platform "has laid grounds for a sustainable and viable process aimed at finding a political and diplomatic solution to the Syrian crisis based on the United Nations Security Council Resolution 2254."

Putin thanked his Iranian and Turkish counterparts - Hassan Rouhani and Recep Tayyip Erdogan - for participating in the Sochi summit. "I am confident that today’s talks will prove to be fruitful and the agreements we will achieve will contribute to the efforts to bring peace and security back to Syria and ensure stability in the Middle East," the Russian president said.

This is the fourth summit of the guarantor countries of the Astana process on Syria. The first meeting of the Astana trio was held in Sochi on November 22, 2017. The second summit took place in the Turkish capital of Ankara on April 4, 2018.
