The UAE says, travel and trade could resume between Qatar and boycotting Gulf countries within a week.
This comes after Doha restored diplomatic ties with Saudi Arabia and its Arab allies, ending more than three years of blockade.
The U.S.-brokered deal was officially signed at the Gulf Cooperation Council summit on Tuesday.
Abu Dhabi says, however,.restoring diplomatic ties with Doha requires more time,. as parties work to rebuild trust.
The so-called "quartet" of Gulf region nations had imposed an embargo on Doha in 2017, for allegedly supporting terrorism and having warm ties with Iran.
