GCC endorses return to Iran nuclear deal
All group members have endorsed mutual return to deal as Washington and Tehran prepare to resume negotiations in Vienna
Washington Nov 19, 2021
"The Gulf Co-operation Council (GCC) on Thursday [18th November 2021] joined Egypt, Jordan, France, Germany and the UK in calling for a return to the nuclear deal following a meeting with US Iran envoy Robert Malley in Saudi Arabia.
The 12 countries issued a joint statement noting that “a return to mutual compliance with the [nuclear deal] would benefit the entire Middle East, allow for more regional partnerships and economic exchange, with long-lasting implications for growth and the well-being of all people there, including in Iran".
Several GCC states expressed scepticism when the nuclear deal was first negotiated under former president Barack Obama, with Saudi Arabia describing it as “flawed”.
But sentiments have changed in the intervening years. Dr Anwar Gargash, diplomatic adviser to UAE President Sheikh Khalifa, said this week that his country seeks to de-escalate tension with Tehran through dialogue.
The unified GCC call for a return to the deal comes before a seventh round of indirect talks between the US and Iran scheduled for November 29."
