In a statement released on Thursday, Khatibzadeh reacted to the recent remarks made by Saudi Crown Prince Mohammed bin Salman about Tehran-Riyadh relations and the region.
"Iran and Saudi Arabia, as two important countries in the region and the Muslim world, can enter a new chapter of interaction and cooperation to achieve regional peace, stability, and development by adopting constructive and dialogue-based approaches," the spokesman said.
"By presenting proposals and initiatives for dialogue and cooperation in the Persian Gulf region, including the Hormuz Peace Endeavour (HOPE), the Islamic Republic of Iran has been a pioneer in the path of amity and regional cooperation, and welcomes the change in Saudi Arabia's tone," Khatibzadeh added.
He also expressed hope that the holy month of Ramadan, the month of divine mercy, would be a blessed beginning for convergence among the Islamic society and end of war, displacement, and insecurity in this region.
Earlier, the Saudi crown prince had told the Saudi-owned al-Arabiya TV that the kingdom viewed Iran as a neighboring country and aspired to have good relations with it.
“At the end of the day, Iran is a neighboring country. All we ask for is to have a good and distinguished relationship with Iran,” Mohammed bin Salman had said.
Diplomatic relations between Tehran and Riyadh soured following the January 2016 execution of Shiite cleric Sheikh Nimr al-Nimr, an outspoken critic of the Saudi monarchy, in Saudi Arabia. Riyadh cut ties with Tehran afterwards, responding to attacks by angry protesters on its embassy in the Iranian capital.
Saudi Arabia’s military campaign against Yemen as well as the death of hundreds of Iranian Hajj pilgrims in a deadly crush in Saudi Arabia’s Mina in September 2015 had prepared the ground for the deterioration of tensions between Tehran and Riyadh.
