"We confirm that trilateral ministerial Astana peace talks on Syria will be held on April 22 via video conference," TASS News Agency quoted the Russian Foreign Ministry as saying.
The latest round of Astana talks took place in Kazakhstan’s capital, Nur-Sultan in December last year.
The next meeting was to be held in Iran in March 2020, but the meeting was postponed due to the coronavirus pandemic.
Iran’s Foreign Minister Mohammad Javad Zarif will participate in the Wednesday meeting two days after a visit to Syria.
In Syria, he held talks with Syrian President Bashar al-Assad and his counterpart Walid al-Muallem.
Iran’s top diplomat and Syrian president discussed a range of issues including the Astana peace process and the persistence of Turkish military aggression in Syria's embattled northwestern region.
They also talked about ways to develop bilateral relations, particularly in the economic sector, and implementation of joint ventures to serve the interests of the two countries’ peoples.
Since January 2017, Moscow, Tehran, and Ankara have been mediating peace negotiations between representatives from the Damascus government and opposition groups in a series of rounds held in Nur-Sultan, previously named Astana, and other places. The talks are collectively referred to as the Astana peace process.
The first round of the Astana talks commenced a month after the three guarantors joined efforts and brought about an all-Syria ceasefire. The three states act as the guarantors of that truce.
The negotiations have helped significantly reduce the violence gripping the Arab country by establishing four de-escalation zones there. They have also paved the way for the formation of a Constitutional Committee.
