France has called for a swift lifting of sanctions that target Qatari nationals in an effort to ease a month-long rift between the Gulf country and several of its neighbours.
Saudi Arabia, the United Arab Emirates, Bahrain and Egypt imposed sanctions on Qatar on June 5, accusing it of financing extremist groups and allying with the Gulf Arab states' arch-foe Iran. Doha denies the accusations.
"France calls for the lifting, as soon as possible, of the measures that affect the populations in particular, bi-national families that have been separated or students," French Foreign Minister Jean-Yves Le Drian told reporters in Doha, after he met his counterpart Sheikh Mohammed bin Abdulrahman al-Thani.
Mr Le Drian was speaking alongside Sheikh Mohammed, hours after his arrival in Doha. He is the latest Western official to visit the area since the crisis began.
Later in the day he flew to Jeddah, where he repeated his concerns about the effects of the standoff in a televised press appearance with Saudi Foreign Minister Adel al-Jubeir.
Mr Jubeir said any resolution of the crisis should come from within the six-nation Gulf Cooperation Council.
"We hope to resolve this crisis within the Gulf house, and we hope that wisdom prevails for our brothers in Qatar in order to respond to the demands of the international community - not just of the four countries," he said.
He reiterated that Qatar should not support terrorist groups and their financing or host their members and should end incitement through the media.
Qatar has repeatedly denied such accusations and rejected demands to close down the Al Jazeera network as initially requested by the boycotting states.
Mr Le Drian, who will visit the UAE and Gulf mediator Kuwait on Sunday, follows in the steps of other world powers in the region, including the US, whose Secretary of State Rex Tillerson sought to find a solution to the impasse this week.
