The drying up of the Saudi tap makes a visit to Egypt this weekend by the crown prince of Abu Dhabi all the more interesting. Mohammed bin Zayed Al Nahyan was in Cairo on Friday for one-on-one talks with President Abdel Fattah El Sisi, after which the two sat down with a wider group of government officials from both sides. An emailed readout from Ittihadiya includes the standard / customary reciprocal recitation of pledges of Egyptian support for the UAE, of Emirati support for Egypt, and of the importance of working together for the common good of the Arab world. We’ll be paying close attention to comment on Egypt coming out of the UAE in the days ahead given earlier reports that the Emiratis had largely lost patience with Egypt this past summer. Word on the diplomatic circuit is that the visit aimed to mediate between Cairo and Riyadh.
