The Iranian President's Deputy Chief of Staff for Political Affairs, Mohammad Jamshidi, made the announcement in a post on his Twitter account on Sunday, saying the Saudi king has extended the invitation in a letter.

The two regional heavyweights have recently announced a Chinese-brokered deal to restore ties seven years after they were severed. They had held five rounds of negotiations in the Iraqi capital of Baghdad since April 2021.

"In a letter to President Rayeesi, the King of Saudi Arabia welcomed the deal between the two brotherly countries, (and) invited him to Riyadh," he wrote, adding that the Saudi King has called for establishing economic and regional cooperation between the two countries.

The senior Iranian official stated that Rayeesi has welcomed the invitation.

After several days of intensive negotiations hosted by China, Iran and Saudi Arabia finally clinched a deal on March 10 to restore diplomatic relations and re-open embassies and missions within two months.

According to a joint statement, Tehran and Riyadh have stressed the need to respect the national sovereignty and refrain from interfering in the internal affairs of one another.

The two countries have agreed to implement a security cooperation agreement signed in April 2001 and another accord reached in May 1998 to boost economic, commercial, investment, technical, scientific, cultural, sports, and youth affairs cooperation.

Saudi Arabia severed diplomatic relations with Iran in January 2016 after Iranian protesters, enraged by the execution of prominent Shia cleric Sheikh Nimr Baqir Al-Nimr by theRiyadh government, stormed its embassy in Tehran.

Iranian Foreign Minister Hossein Amir Abdollahian told reporters on Sunday that the two countries had agreed to hold a meeting between their top diplomats.

He added that three locations for the talks had been suggested, without specifying where.
