Turkish President Recep Tayyip Erdogan has told Russian President Vladimir Putin that calls for peace and negotiations should be supported by a unilateral declaration of ceasefire and a vision of “a fair solution,” according to a government statement.

In a phone call with Putin on Thursday, Erdogan highlighted that previous negotiations have yielded positive results, such as the establishment of the Black Sea grain corridor, prisoner exchanges and initiatives to create a safe zone around the Zaporizhzhia nuclear power plant.

Turkey has called for an end to the conflict on multiple occasions and throughout 2022 Erdogan attempted to position himself as the broker between Putin and the West.

On December 22, US Secretary of State Antony Blinken spoke to Turkish Foreign Minister Mevlut Cavusoglu to thank Turkey for its “efforts to ensure the continuation of the UN-brokered Black Sea Grain Initiative,” according to a statement from US State Department spokesman Ned Price.
