Ankara, for its part, suspects that the UAE backed a network led by a U.S.-based Turkish Muslim cleric which Turkey accuses of orchestrating a failed coup in 2016.
The crown prince was welcomed at the Turkish presidential complex in Ankara in a ceremony that included a 21-gun salute.
He and Erdogan later oversaw the signing of almost a dozen cooperation agreements, including in trade, energy and the environment, as well as deals allowing direct investments and cooperation between the two countries’ stock exchanges and central banks.
Turkey’s state-run Anadolu Agency meanwhile, quoted the head of the Abu Dhabi Development Holding Company as saying that the UAE has allocated a $10 billion fund for investments in Turkey.
The prince’s visit to Turkey is viewed as part of a wider effort by the UAE to recalibrate its foreign policy following an unsuccessful attempt to isolate fellow Gulf state Qatar in 2017. Turkey, an ally of Qatar, rushed to support Doha amid an embargo imposed by the UAE and three Arab states. Turkey has since deepened its military ties with Qatar.
The Arab quartet at the time demanded a series of reversals by Qatar, including the expulsion of Turkish troops, but Qatar rejected the demands as violations of its sovereignty. The dispute was resolved earlier this year with an agreement signed in Saudi Arabia.
Turkey is also engaged in an effort to mend its frayed ties with regional powers, including Egypt and Saudi Arabia, after finding itself increasingly isolated internationally.
Erdogan said after his meeting with Sheikh Tahnoun in August that he expected increased investments from the UAE in Turkey.
Turkey’s trade and finance ministers visited Abu Dhabi and Dubai on Tuesday, a visit that further helped set the stage for Wednesday’s top level meeting in Ankara.
