"So far Kuwait hasn't received any demands from any GCC nations or even a list of the so-called accusations," Sheikh Mohammed bin Abdulrahman said on Saturday in an interview with Qatar TV.
"We're just confused about what these demands could be.
"The fact that they don't even have clear demands ready shows that all of their accusations are baseless."
Saudi Arabia, the UAE, Bahrain, along with Egypt, cut diplomatic and transport ties with Qatar on June 5, accusing the country of supporting "extremism" and their regional ally, Iran - charges that Qatar has repeatedly denied.
The three Arab Gulf countries also ordered Qatari nationals to leave within 14 days, while Saudi, UAE and Bahraini citizens were also given the same timeframe to leave Qatar.
They later issued a list of 59 people and 12 groups with links to Qatar, alleging that they have ties to "terrorism".
Speaking in London on Friday, Adel al-Jubeir, Saudi Arabia's foreign minister, said his country was drawing up a list of "grievances" involving Qatar.
"I would not call them demands. I would say it is a list of grievances that need to be addressed and that the Qataris need to fix," he said.
Jubeir did not detail what complaints could be made, but added that they will be presented "very soon".
The blockade has disrupted imports of food and other materials into Qatar and caused many foreign banks to scale back their business with the country.
Amnesty International, the rights group, has criticised the move, accusing the Gulf Arab states of toying with the lives of thousands of people in their dispute with their neighbour.
