Saudi Foreign Minister Adel al-Jubeir said on Tuesday that there would be no negotiations over demands by the kingdom and other Arab states for Qatar to stop supporting terrorism.
Doha retorted that the allegations against it and demands were baseless and unacceptable. Qatar has previously also said the demands were aimed at curbing its sovereignty.
Asked by reporters on a visit to Washington if the demands were non-negotiable, Saudi's Jubeir said: "Yes."
"We made our point, we took our steps and it's up to the Qataris to amend their behavior and once they do things will be worked out but if they don't they will remain isolated," Jubeir said.
