Hawzah News Agency - "Yes, he has asked Erdogan on the phone, whether they could meet in Buenos Aires. Erdogan's answer was 'Let's see'," Cavusoglu told Germany's Sueddeutsche Zeitung newspaper.
Erdogan and Prince Mohammed will attend the G-20 meeting in Argentina later this week. "At the moment there is no reason not to meet with the crown prince," Cavusoglu said.
Asked if he knew for sure who in Riyadh gave the order to kill Khashoggi, Cavusoglu said that the team would not have acted on its own, but could not say anything else without proof.
Cavusoglu said Riyadh had offered to send identikit photos of local helpers who assisted in the cover-up. "Why identikit pictures? The Saudis know the names," he said.
Turkey says it has recordings related to the killing which it shared with Western allies. Cavusoglu said he had listened to the recordings and that Khashoggi was killed within seven minutes.
"It was premeditated murder," he told the German newspaper, rather than a last resort after they failed to convince him to return to Saudi Arabia.
"It can be heard how the forensics expert instructs the others: they should listen to music while he cuts up the body. One notices how he enjoys it."
