On Saturday, Lavrov, Iran's Javad Zarif and Turkey's Mevlut Cavusoglu met in Moscow to discuss the situation in Syria, including the strike by Western countries on Syria, and preparations for the ninth round of the reconciliation talks in Astana format. The three nations launched their peace attempt in the Kazakhstan capital Astana a year ago, which they are pursuing independently of a United States and UN-backed Geneva initiative.
The ministers emphasised the success of their peace talks in Astana, which Lavrov said are "firmly standing on their feet".
In the trilateral meeting, Iran, Russia and Turkey will stress on the continuation of political efforts and reject any measure damaging Syria's territorial integrity or sovereignty, Zarif added.
Critics of the Astana talks are "trying to show that they today decide all the affairs in our world, but fortunately their time has passed", Lavrov said.
"We will ensure that this aid is provided in the most effective way".
Meeting his Turkish counterpart, the Russian diplomat stressed the "great importance" both Russian President Vladimir Putin and President Recep Tayyip Erdogan attach to improving relations.
However, differences have emerged over the future of Syrian President Bashar al-Assad, and whether he should stay in power.
Iran and Russian Federation on Saturday slammed Western strikes on Syria over the alleged chlorine or sarin gas attack.
Attempts are being made to hinder the peace process in Syria, particularly to prevent the establishment of a constitutional committee, Lavrov said. "We will continue solving important tasks related to de-escalation, easing tensions and reducing the conflict potential".
