Russia, Turkey and Iran signed on Thursday a memorandum on creating safe zones in Syria after a new round of peace talks held in the Kazakh capital Astana.
Russia, Turkey and Iran act as guarantors of the Astana peace process.
Kazakh Foreign Minister Kairat Abdrakhmanov said that next Syria peace talks would be held in Astana in mid-July.
Erdoğan and Putin voiced support for a proposal, backed by U.S. President Donald Trump, to create so-called safe zones in Syria to protect civilians from the fighting.
"We all take the view that we need to... create mechanisms that would guarantee a cessation of bloodshed and create the conditions for the start of a political dialogue. In this respect our position and that of the Turkish president totally coincide," Putin said.
