DUBAI, United Arab Emirates -- Russian President Vladimir Putin traveled to Saudi Arabia on Monday, meeting with the oil-rich nation's king and crown prince as he seeks to cement Moscow's political and energy ties across the Mideast.
Putin received all the trappings of a state visit, with a mounted guard escorting his limousine to King Salman's Al-Yamamah palace in Riyadh on his first visit to the kingdom since 2007.
In the intervening years, the Arab Spring roiled the wider Mideast as Putin would partner with Iran in backing Syrian President Bashar Assad in that country's still-raging war. Saudi Arabia unsuccessfully backed those trying to oust Assad.
But more recently, Russia joined OPEC in lowering their production beginning in 2017, the first such cut for the cartel in a decade. It reduced production by 1.2 million barrels per day, with 800,000 coming from OPEC and 400,000 coming from non-OPEC members, an arrangement now known as OPEC+.
That helped boost energy prices. Crude oil sold for over $100 a barrel in the summer of 2014 before bottoming out below $30 a barrel in January 2016. On Monday, it traded just under $60 a barrel.
"The OPEC+ production cuts agreement has been extended thanks to active participation of our countries," Putin said.
Putin listened to a Saudi military band play Russia's national anthem, then greeted officials and sat with King Salman for a conversation captured by state television. Earlier, a broadly grinning Saudi Crown Prince Mohammed bin Salman walked up to greet Putin on his arrival. The crown prince later engaged in a conversation with Russian Foreign Minister Sergey Lavrov.
Putin even paused to admire a traditional curved knife, a janbiya, worn by a member of the Saudi honor guard on hand.
In brief remarks, the 83-year-old King Salman praised relations between Riyadh and Moscow, especially energy agreements. At a recent OPEC meeting in Abu Dhabi, Saudi Energy Minister Prince Abdulaziz described the arrangement as "'til death do us part."
Prince Abdulaziz briefed both leaders before a signing ceremony at the palace on 20 agreements between the two nations.
Putin praised King Salman's efforts at maintaining relations, noting the monarch's 2017 trip to Moscow.
"Russia sees the expansion of friendly and mutually beneficial ties with Saudi Arabia as particularly important," he said.
Saudi Arabia likely wants to talk about ongoing tensions gripping the wider Middle East, where the kingdom is locked in a standoff with its archrival Iran and Turkey's military campaign in Syria has launched an added crisis.
Saudi Arabia also remains worried about Iran. Since President Donald Trump pulled out of Tehran's nuclear deal with world powers over a year ago, risks have risen in the Persian Gulf. Since the summer, a series of attacks have targeted oil tankers in the region.
These attacks culminated in a Sept. 14 drone-and-cruise-missile assault that knocked out half of Saudi Arabia's oil production. The U.S. blames Iran for the attack, something Tehran denies. Yemen's Houthi rebels, whom the kingdom has been battling since March 2015, claimed the assault, though analysts say the missiles used wouldn't have the range to reach the targets in the kingdom from Yemen.
"We look forward to working with Russia to achieve security and stability and fight terrorism," King Salman said.
