Abu Dhabi is Erdogan's last stop in a Gulf tour that included the Saudi Red Sea city of Jeddah and Doha.
Reaping the benefits of his diplomatic efforts, Saudi Arabia agreed on Tuesday to buy Turkish drones in the biggest defence contract in Turkey's history.
Turkey also sent troops to Doha when Saudi Arabia and the UAE imposed a blockade on Qatar in 2017.
Abu Dhabi agreed last year to a $5-billion swap deal in local currencies with Ankara to help its struggling lira.
