Doha can broker talks between Gulf states and Iran now that GCC ties are restored, Qatar's Foreign Minister Sheikh Mohammed Al Thani told Bloomberg TV on Tuesday.
His comments came a day after Omar Ghobash, the UAE's Assistant Minister for Culture and Public Diplomacy, repeated to CNBC that the country backed conditional talks with Iran that tackle regional meddling and its ballistic missiles.
"Qatar will facilitate negotiations, if asked by stakeholders, and will support whoever is chosen to do so. We want the accomplishment, we want to see the deal happening," Mr Al Thani said.
The issue of the 2015 Iran nuclear accord is back on the table because incoming US President Joe Biden is keen to restart talks with Tehran about two years after Donald Trump withdrew from the deal.
Qatar maintained close ties with Iran in recent years and the countries share several oil and gas projects.
Relations were mended between Qatar and Saudi Arabia, the UAE, Bahrain and Egypt before the 41st GCC summit at Al Ula in Saudi Arabia this month.
The move ended a three-year Gulf crisis and travel, economic and diplomatic ties have started to resume.
Qatar's Emir Sheikh Tamim Al Thani attended the summit for the first time since 2017, when the four countries cut ties with Doha after accusing it of supporting extremist groups and meddling in the internal affairs of neighbouring states. Doha denied the accusations.
