After a lengthy historical impasse, common strategic, regional and economic interests brought about an unusual partnership between Saudi Arabia and Turkey. Relations were strengthening under the pressure of the Arab uprisings, in which both countries were destined to coordinate their support for the Syrian rebels and counterbalance Iran’s expansion in the region. Yet, in the wake of the Egyptian coup, this partnership appears to be strained as the two countries’ visions collided over the overthrow of Egyptian President Mohammed Morsi.

The Turkish leadership made clear its objections to deposing an Islamist leader with whom it had close ideological affinities. Prime Minister Recep Tayyip Erdogan called on the UN Security Council to meet after the massacre of Egyptian protesters, and reprimanded Europe for remaining silent. In July, it was reported that he was puzzled by Saudi backing of the coup and rhetorically asked Saudi Foreign Minister Saud al-Faisal, “How could a country claiming to uphold Islam and Sharia support the overthrow of an elected Islamist president who came to power after fair elections?”

The Turkish leadership appealed to the Organization of the Islamic Conference (OIC) chief Ekmeleddin Ihsanoglu, to condemn the coup. Deputy Prime Minister Bekir Bozdag reprimanded Ihsanoglu over the organization’s inaction following the Egyptian army’s heavy crackdown on Muslim Brotherhood protesters. Bozdag called on the OIC chief to resign for “dishonorable passivity.”

After this most recent episode, it seems that Erdogan will not be endearing Foreign Minister Saud al-Faisal again as he did when the UN General Assembly voted to grant Palestine the status of non-member observer state in 2012. Yet, it is not clear whether this current impasse will have long-lasting negative consequences for cooperation between the two countries. Saudi Arabia needs Turkey in Syria, while Turkey remains eager to attract more Saudi investment, estimated at more than $1.9 billion.
