DUBAI: Qatar is working to de-escalate tension in the region by advocating for a return to the 2015 Iran nuclear agreement, state media quoted its foreign minister as saying.

"The State of Qatar is working on de-escalation through a political and diplomatic process to return to the nuclear agreement," Foreign Minister Sheikh Mohammed bin Abdulrahman Al-Thani said on Wednesday, according to state news agency QNA.

The remarks came in briefing notes about two separate calls earlier in the week between Thani and US Special Representative for Iran Robert Malley and US National Security Advisor Jake Sullivan.

US President Joe Biden's administration is exploring ways to restore the nuclear deal that Iran signed with world powers but abandoned in 2018 by former President Donald Trump, who restored sanctions.

Thani said Qatar's communication was going on with both Iran and the United States, given the strategic ties Qatar holds with both.

A breakthrough was reached last month to resolve a three-year dispute between Gulf Arab states and Qatar.

The pact was one in a series of Middle East deals sought by the Donald Trump administration - the others involving Israel and Arab states - aimed at building a united front against Iran.
