Russian President Vladimir Putin will meet Saudi Arabia's defense minister this week in a meeting aimed at boosting bilateral ties after years of tensions over Syria, his aide said Wednesday.

Putin will meet Prince Mohammed bin Salman, believed to be a favored son of King Salman, on Thursday on the sidelines of the Saint Petersburg International Economic Forum, the Kremlin's top foreign policy aide Yury Ushakov said.

Deputy Crown Prince Mohammed, aged 29 according to the website of the Saudi embassy in the US, was elevated to the post of defense minister the day Salman acceded to the throne in January.

Ushakov said Putin and the Saudi prince would discuss a range of international issues including the Syria crisis and the fight against ISIL Takfiris as well as ramping up economic ties.

"Undoubtedly the (meeting) is very important and speaks of the interest of both sides -- Russian and Saudi -- in ramping up ties to a wholly new level," Ushakov said.

He said he was not aware if Russia and Saudi Arabia -- a traditional ally of the United States -- would discuss oil prices.

The two countries are set to ink a number of agreements on the forum's sidelines, the Kremlin said.
