On the night of July 15, 2016, while a coup attempt was unfolding in Turkey, two capitals — Moscow and Tehran — stayed on alert. Presidents Vladimir Putin of Russia and Hassan Rouhani of Iran were the first to call their Turkish counterpart, Recep Tayyip Erdogan, to express support for the elected government in Ankara.
Tehran’s support compounded Turkish hopes of expanding economic ties, which had been on the rise since Iran’s nuclear deal with world powers and the ensuing lifting of sanctions. Turkish entrepreneurs felt excited over the prospect of new opportunities in Iran amid expectations of a multibillion-dollar investment and development drive in the neighboring country.
