MOSCOW: Russia is preparing for President Vladimir Putin to visit Saudi Arabia after he received an invitation from Saudi King Salman, agencies cited Deputy Foreign Minister Mikhail Bogdanov as saying on Friday. The visit will happen at a time depending on Putin’s schedule, Bogdanov was quoted as saying. He did not say what the talks in Saudi Arabia might touch upon or when Riyadh’s invitation to Putin was made. Russia and Saudi Arabia have cooperated closely on global oil markets to curb production between OPEC and non-OPEC countries. In October 2017, King Salman became the first Saudi monarch to visit Russia, meeting Putin in the Kremlin. In July, Saudi Crown Prince Mohammed bin Salman shared a box with Putin at the opening match of Russia’s football World Cup. “The visit is being worked on, the timing will depend on the president’s schedule,” Bogdanov was quoted as saying by TASS. He did not say when the visit would happen. “It’s the presidential administration’s prerogative, but I think a visit will logically follow. The president has an invitation from King Salman,” he was quoted by RIA as saying.
