Amir-Abdollahian was visiting professor at the Faculty of International Relations of the Ministry of Foreign Affairs. In January 2023, Faisal speaking at a panel at the
World Economic Forum in
Davos reiterated that "Riyadh is trying to find a dialog with Iran". The two countries announced the resumption of relations on 10 March 2023, following a deal brokered by China. It could lead the way to easing of the
Iran–Saudi Arabia proxy conflict, thus bringing stability to Yemen, Syria, Iraq, Lebanon and Bahrain. Amir-Abdollahian met with the Qatar's Foreign Minister Mohammed bin Abdulaziz Al Khulaifi in July 2023. They discussed joint work on infrastructure projects. During a meeting with UN diplomat
Tor Wennesland on 14 October 2023, Abdollahian warned that Iran could intervene in the
Gaza war if Israel launched a
ground invasion of Gaza. On 15 October 2023, Abdollahian met with
