We have signed a Sister City Protocol between Çatalköy-Esentepe Municipality and Sultanbeyli Municipality of Istanbul, Republic of Turkey, with the aim of strengthening economic, scientific and technical cooperation, developing mutual assistance, and conducting joint studies in the fields of culture, education and health. I hope that this strong cooperation to be established between the two municipalities will be beneficial to both cities, and I would like to thank our Sultanbeyli Mayor, Mr. Ali Tombaş, for his kind hospitality.
