Gulf analyst Dr Kristian Coates Ulrichsen, a fellow for the Middle East at the Baker Institute for Public Policy at Rice University in Houston, said that the tensions between Saudi-led GCC and Qatar show no sign of abating.

"I don't see any imminent signs of a thaw in the blockade of Qatar by Saudi Arabia and the UAE", he said.

He added: "The Qatari Prime Minister's participation at the Mecca Summits in Saudi Arabia at the end of May did not lead to any breakthrough, as some beforehand had hoped it might."

He also said: "The leadership in Abu Dhabi remains resolutely opposed to any normalization of ties and easing of the blockade."
