Following the assassination of prominent journalist Jamal Khashkiji at the Saudi consulate in Istanbul, Turkey, in 2018, President Erdogan pointed the finger directly at Saudi Crown Prince Mohammed bin Salman for the assassination. After that, relations between the two most influential countries in the Muslim world began to deteriorate rapidly. Within a year, relations between the two countries deteriorated to the point that Saudi Arabia officially banned the import of goods from Turkey. On the other hand, President Erdoغانan never misses an opportunity to criticize the Saudi royal family. The two governments continued to throw mud at each other for a long time through the state media of both the countries. But in April this year, Turkish President Recep Tayyip Erdogan's surprise visit to Saudi Arabia and photos of him shaking hands with Saudi Crown Prince Mohammed bin Salman in Jeddah showed signs of a change in relations.
