Abu Dhabi - Qatar faces further isolation and possible expulsion from the Gulf Cooperation Council (GCC) if its response to a list of demands made nearly two weeks ago is not satisfactory, state-backed Gulf media said Wednesday. The foreign ministers of Saudi Arabia, the United Arab emirates, Egypt and Bahrain are due to meet in Cairo to discuss Qatar's reply to 13 demands they sent to Qatar in return for the lifting sanctions imposed last month. The dispute revolves around allegations that Qatar supports extremists, including ISIS(Daesh), which has been designated a terrorist organisation by Saudi Arabia, the UAE and Egypt. Qatar denies it supports terrorism and says Arab countries want to control its foreign policy. Qatari Foreign Minister Sheik Mohammed bin Abdulrahman al-Thani said at a joint news conference with his German counterpart on Tuesday that its response was "given in goodwill and good initiative for a constructive solution", but insisted that Doha would not compromise on its sovereignty. Gulf officials have said the demands are not negotiable, signalling more sanctions are possible, including "parting ways" with Doha - a suggestion it may be ejected from the GCC, a regional economic and security cooperation body founded in 1981. "Qatar is walking alone in its dreams and illusions, far away from its Gulf Arab brothers, after it sold every brother and friend and bought the treacherous and the one far away at the highest price," the editor of the Abu Dhabi government linked al-Ittihad newspaper wrote in an editorial.
