Iranian Foreign Minister Hossein Amirabdollahian arrived in Riyadh today, on his first official visit to Saudi Arabia since the restoration of diplomatic relations between the Middle East’s two biggest powers, Iranian state media reported.

Iran and Saudi Arabia reached an agreement on March 10, brokered by China, to end their diplomatic rift and restore relations after years of hostility during which the two countries had supported rival camps in Syria, Lebanon and Yemen.

The Sunni kingdom severed ties with Shiite Iran in 2016 after protesters attacked the Saudi embassy in Tehran in retaliation for Riyadh’s execution of a prominent Shiite cleric.

Amirabdolakhian “arrived a few minutes ago at Riyadh airport for a one-day visit and was received by the deputy foreign minister of Saudi Arabia,” the official Irna news agency reported early at noon.

The head of Iranian diplomacy will meet with his Saudi counterpart as well as other high-ranking Saudi officials, the agency added.

The Iranian Foreign Minister is accompanied by Alireza Enayati, Iran’s new ambassador to Saudi Arabia.

The visit will focus on “bilateral relations, regional and international issues,” Iran’s state-run Irib TV reported earlier today.

The restoration of Riyadh-Tehran relations was sealed when the Islamic Republic reopened its embassy in Riyadh on June 6.

In mid-June, Saudi Foreign Minister Prince Faisal bin Farhan had met with Iranian officials in Tehran during his visit to Iran, the first visit by a Saudi foreign minister to Iran in 17 years. For its part, Saudi Arabia reopened its embassy in Iran in early August.

In another early sign of mending bilateral relations, military officials from the two countries met in Moscow on the sidelines of a security conference, Iranian state media reported yesterday, Wednesday.

The enmity of the two largest powers in the Middle East manifested itself in often opposing positions on regional issues.

Since restoring ties in March, Saudi Arabia has restored ties with Tehran’s ally Syria and stepped up peace efforts in Yemen, where it leads a military coalition backing the Yemeni government against Houthi rebels, who are close to Iran.

The Islamic Republic, for its part, has stepped up its diplomatic activities in recent months and is trying to forge closer ties with other Arab countries in order to reduce its isolation and boost its economy.
