Saudi Arabia and its allies today criticised Qatar’s refusal to accept conditions to end the Gulf’s biggest diplomatic crisis in years as a threat to regional security.Saudi Arabia, the United Arab Emirates, Egypt and Bahrain broke ties with Qatar early last month.On June 22, they issued a 13-point list of demands, including the shutdown of broadcast giant Al-Jazeera, as a prerequisite to lift the sanctions, which include the closure of Qatar’s only land border and suspension of all flights to and from the country.Mr Johnson has meetings with his Kuwaiti Foreign Secretary Sheikh Sabah Khaled Al-Hamad Al-Sabah and will also travel to Qatar to meet the Emir, Sheikh Tamim bin Hamad Al Thani.Qatar has said those demands reveal how the Saudi-bloc’s pretext for the severance of ties with Doha, i.e. the accusation that Qatar sponsors terror, is just that: a pretext.In a statement attributed to an unnamed senior foreign ministry official released later Friday, Qatar called allegations made by the quartet against it false and tantamount to “defamation in contradiction with the established foundations of worldwide relations”.In a statement attributed to an unnamed senior foreign ministry official released later, Qatar said its position on terrorism “is consistent and known for its rejection and condemnation of all forms of terrorism whatever the causes and motives are”. It went on to say that Qatar “is an active member committed to global conventions in combating terrorism and its financing at the regional and worldwide levels”. The source said, however, that Qatar was ready to “cooperate and review all claims that do not contradict the sovereignty of the State of Qatar”.Several countries, including the United States, have urged the Arab states to resolve their differences.Johnson said progress could be made to heal the rift between Qatar and other Arab states, although a solution was unlikely to be found immediately. Qatar’s answer to a list of demands from four countries lined up against it may be shrouded in secrecy, but the message it delivered this week was clear enough: it is not about to roll over.On Wednesday, German Foreign Minister Sigmar Gabriel concluded his three-nation tour to Qatar, UAE and Kuwait, in a bid to broker an end to the standoff.His Highness the Emir Sheikh Tamim bin Hamad al-Thani and the UK Foreign Minister Boris Johnson discussed on Saturday the latest developments of the GCC crisis and its implications in terms of regional and worldwide stability. He is expected to visit Qatar and Kuwait during his trip.
