Turkish President Recep Tayyip Erdoğan will visit Iran on Sept. 7, his office said Monday.
Reuters reports that Erdoğan will likely meet with Russian and Iranian leaders during his trip.
Russia said nearly two weeks ago that Russian President Vladimir Putin may meet with Erdoğan and Iranian President Hassan Rouhani at the beginning of September.
The three leaders met in April to discuss the developing situation in Syria, according to Reuters.
Relations have recently become tense between the U.S. and Turkey.
One particular point of animosity is Turkey’s ongoing imprisonment and alleged abuse of American pastor Andrew Brunson.
Since the refusal, the Turkish lira hit record lows and Turkey’s economy has continued to stagnate.
Trump said last Monday that he would not make any concessions with Turkey, the day after the White House rejected Turkey’s offer to release Brunson in exchange for the U.S. ending an investigation into Turkish bank Halkbank.
