CAIRO,
 July 6 (Reuters) - Saudi Arabia's king and crown prince congratulated 
Masoud Pezeshkian on his election as Iran's president, state news agency
 SPA reported on Saturday.
"I
 affirm my keenness on developing and deepening the relations between 
our countries and people and serve our mutual interests," SPA quoted 
Saudi Crown Prince Mohammed bin Salman as saying.
In
 March 2023, Iran and Saudi Arabia signed a landmark China-brokered deal
 to re-establish relations after years of regional rivalry.
Since then, officials from both sides continued talks to bolster ties.
