"We have made significant progress in the last few days thanks to the continuing efforts of Kuwait but also thanks to strong support from President Trump", Saudi Foreign Minister Prince Faisal bin Farhan Al Saud told a Rome conference via videolink.
Saudi Arabia, the United Arab Emirates, Bahrain and Egypt imposed a diplomatic, trade and travel boycott on Qatar in June 2017, accusing Doha of supporting terrorism and having ties with Iran that were deemed too close. In return, Qatar may withdraw the worldwide lawsuit filed against Saudi Arabia.
But Prince Faisal's remarks did come just hours after the top diplomat from mediator nation Kuwait described the ongoing talks over the crisis as "constructive and fruitful".
He remained hopeful that a deal could soon be reached to resolve disputes between the gulf countries to restore regional stability following recent progress in talks led by Kuwait and the USA.
Dr. Al-Hajraf extended thanks, appreciation and congratulations to their Majesties and Highnesses, the leaders of the GCC states on this blessed day, and to the members of the Cooperation Council for the Arab States of the Gulf, who are witnessing the beginning of a new phase led by their Majesties and Highnesses, the leaders of the GCC states to achieve goodness, development, security and prosperity for the Council, and its state members.
As the price for lifting the blockade, the four nations set a 13-point ultimatum for Qatar, which included shutting down the Al Jazeera Media Network.
On Friday, Kuwait announced progress towards ending the row.

Care home residents, health and care staff are also among the clinically extremely vulnerable and will receive the vaccine on priority basis.
"Right now there are some movements that we hope will put an end to this crisis", said Sheikh Mohammed, speaking via video link.
Sheikh Mohammed bin Abdulrahman Al Thani cautioned that the crisis wouldn't be immediately resolved in comments to Italy's annual Mediterranean Dialogue. "We believe actually that Gulf unity is very important for the security of the region".
Al Thani said any solution should be "holistic" and based on mutual respect.
A return to the agreement, known formally as the Joint Comprehensive Plan of Action (JCPOA), would delight USA allies in Europe, but concern the Gulf states who have criticised U.S. engagement with Tehran.
In November, Tehran said Saudi Arabia was attempting to scapegoat Iran for its own benefit. Qatar, which hosts the region's largest USA military base, denies the charges and says the boycott aims to undermine its sovereignty.
Qatar has repeatedly condemned the decision as unjustified and the allegations as based on false claims and assumptions, saying it was targeted because it followed an independent foreign policy.
In his remarks, Bin Farhan reiterated that Saudi Arabia won't normalize relations with Israel until a Palestinian state is established.
