Moscow, Oct 14, 2019 (AFP) -

Russian President Vladimir Putin will visit Saudi Arabia on Monday, where he is set to seal oil agreements as well as use his influence to defuse rising tensions in the Gulf.

The meeting with King Salman and Crown Prince Mohammed bin Salman comes following attacks on Saudi oil installations that Riyadh and the U.S. have blamed on Iran, an ally of Moscow.

Oil will be "the main topic of discussion" between the leaders, Russian political analyst Fydor Lukyanov said, as a deal between the 24 members of the Organization of the Petroleum Exporting Countries (OPEC) is due to expire next spring.

Russia is not a member of OPEC, headed by Saudi Arabia, but it has worked closely with the group to limit supply and push up prices after a 2014 slump that badly hit the Russian economy.

Moscow and Riyadh -- a traditional ally of Washington -- have made a striking rapprochement in recent years, marked in particular by King Salman's first visit to Russia in October 2017.

A year later, when Crown Prince Mohammed bin Salman was under fire after the assassination of the journalist Jamal Khashoggi in Turkey, Vladimir Putin went out of his way to shake his hand at a G20 summit, to much comment.

In an interview with Arabic-language television channels ahead of his visit, Putin praised his good relations with the King and Crown Prince.

"We will absolutely work with Saudi Arabia and our other partners and friends in the Arab world... to reduce to zero any attempt to destabilize the oil market," he said in the interview broadcast Sunday.

Analyst Lukyanov said that Moscow -- with its older ties to Iran as new links with Saudi -- could "play the role of peacemaker" as tensions between Tehran and Riyadh continue to rise.

Tehran has denied involvement and warned of "total war" in the event of any attack on its territory.

Russia attempted to keep a foot in both camps -- proposing missiles to Riyadh to defend itself, while at the same time warning against "hasty conclusions" regarding Iranian involvement.

Kremlin adviser Yuri Ushakov said the Syria conflict would also feature in the leaders' talks on Monday.

Russia and Iran are allied with the regime of Bashar al-Assad, while the Saudis support the opposition.

But "it is important for Russia that an Arab country participates in the political settlement in Syria," said Lukyanov.

So far "only three non-Arab countries" -- Turkey, Russia and Iran -- are hosting talks, he said.

In terms of business, the visit is expected to result in around 30 agreements and contracts, according to Ushakov.
