Qatar's Foreign Minister on Monday called on neighbouring states to lift their "blockade" of his country before Doha takes part in any negotiations on ending the Gulf diplomatic crisis.
Sheikh Mohammed bin Abdulrahman Al-Thani called measures to isolate Qatar imposed by Saudi Arabia, the United Arab Emirates, Bahrain and others "an act of aggression", adding that lifting them was a "pre-condition" for talks.
"We have to make it very clear for everyone, negotiations must be done in a civilised way and should have a solid basis and not under pressure or under blockade," the foreign minister told reporters in Doha.
"Qatar under blockade -- there is no negotiation. They have to lift the blockade."
On June 5, Saudi Arabia and allied states cut all ties with Qatar, pulling their ambassadors from the emirate and ordering its citizens to repatriate by June 19.
The measures also included closing Qatar's only land border, banning its planes from using their airspace and barring Qatari nationals from transiting through their airports.
Saudi Arabia, the UAE, Egypt, Bahrain and other states accuse Qatar of supporting and funding "terrorism" and of working with regional rival Iran, charges Doha firmly denies.
Sheikh Mohammed's demand came as a UAE minister warned that Qatar's diplomatic isolation could "last years".
