Erdogan's spokesman meanwhile, said that Kuwait - which is mediating between Qatar and its Gulf neighbors - would present a list of demands by four Arab nations from Doha to end the crisis.
Ibrahim Kalin told a group of journalists that the list by Saudi Arabia, Bahrain, the United Arab Emirates and Egypt would comprise "concrete requests and things Qatar must do" but did not provide details. It would be handed over to Doha in the coming days, he said. His comments were reported by the state-run Anadolu Agency.
King Salman and Erdogan also agreed to strengthen ties between Turkey and Saudi Arabia and to meet face-to-face during a G-20 summit in Germany next month, the statement said.
Erdogan has strongly backed Qatar in the crisis with Saudi Arabia and other Arab nations that cut off relations with Doha after accusing it of supporting terrorism. Erdogan vowed not to leave the tiny nation isolated and Turkey's parliament passed legislation permitting the deployment of troops to a Turkish military base in Qatar in a show of support.
