UAE Minister of State for Foreign Affairs Anwar Gargash said on Saturday that instead of discussing a list of demands set by Gulf countries, Qatar decided to leak them to the media.
Speaking in a press conference, Gargash said there has been "no respect" towards the mediation attempts by Kuwait.
Gargash described the media leak as "reckless." He also said that "Qatar seeks to promote an Iranian agenda."
Earlier this week, it was reported that Kuwait handed over a list of demands to Qatar from Saudi Arabia, Bahrain, UAE and Egypt, and has given Doha 10 days to implement them.
The list of demands, according an Associated Press report, included shutting down Al Jazeera, cutting diplomatic ties with Iran and immediately halting the establishing of a Turkish military base in Qatar and ending any military cooperation with the NATO member. According to a Reuters report, the countries have given Doha 10 days to comply.
Gargash described Al Jazeera as a "platform that promotes the agendas of extremist groups in the region."
"We are trying to stop Qatar from supporting terrorism ... We can no longer accept from Qatar what we have accepted in recent years," Gargash said.
Earlier this month, Saudi Arabia, Egypt, the United Arab Emirates and Bahrain designated as terrorists dozens of people and groups with links to Qatar, after severing diplomatic relations with Doha.
The four states accuse Qatar of supporting extremist Islamist militants and Iran.
