A giant poster bearing an image of President Recep Tayyip Erdoğan was hung in a mall in Qatari capital Doha on Friday.
The poster was also signed by hundreds of visitors.
One of the visitors who signed the poster, Salim Hamas, said that the poster was hung in the mall to thank Erdoğan and the Turkish nation for their efforts to solve the Gulf crisis."This poster is a symbolic appreciation for Turkey, the president and the Turks," he said.
"Turkey and Qatar are bound by a strong brotherhood. We love Erdoğan," another Qatari named Maryam also said.
Saudi Arabia, the United Arab Emirates, Egypt and Bahrain cut diplomatic ties with Qatar and severed air, land and sea links with it on June 5 after accusing it of backing extremist groups. Qatar strongly denies the charge and argues the isolation effort is politically motivated.
Throughout the nearly two-month crisis, which began on June 5, Turkey has been calling on the parties to solve the issue through diplomacy and that both the economic and political sanctions would not serve the interests of involved states.
The bloc later issued a tough 13-point list of demands needed to resolve the crisis, including shutting down news outlets including Al-Jazeera, limiting ties with Iran and expelling Turkish troops stationed in the country.
Qatar refused to bow to the demands within a 10-day deadline, and the anti-Qatar bloc has begun to shift its focus toward six principles on combating extremism and terrorism.
