Syrian President Bashar Assad made a surprise visit to Russia to meet President Vladimir Putin on Thursday at his summer residence in the Black Sea resort of Sochi.
The Syrian presidency released a handout showing the two leaders meeting.
Putin's spokesman Dmitry Peskov said Assad informed the Russian leader of his decision to send a delegation to the UN to discuss reforming the country's constitution. The UN has hosted several rounds of peace talks in Geneva that have made no progress toward ending the conflict.
The Syrian president said Syria is making progress in fighting "terrorism."
"We have evaluated the military situation and it was positive as for the steps that were achieved in the process of countering terrorism and especially the effect of these military actions on restoring the normal situation and the return of the people to their homes,” Assad said.
A posting on the Syrian presidency's Facebook page said the two leaders consulted on various issues of mutual interest and the latest political and military developments in Syria.
"During today's meeting we have agreed upon the next steps with the Syrian president related to countering terrorism and the terrorist groups in Syria,” Putin said.
Assad confirmed he will send a list of candidate names as soon as possible to the United Nations, for membership in a committee that would discuss the constitution. Putin said Russia welcomes and supports this decision based on agreements reached in national dialogue meetings in Sochi.
Assad said he also discussed with Putin economic cooperation and growing investments by Russian companies in Syria.
Russia has been a key ally of Assad throughout the seven-year Syrian civil war. Moscow launched an air campaign on behalf of Assad's forces in 2015 that tipped the conflict in his favor.
Assad previously visited Russia and met with Putin in November 2017 and October 2015, and Putin traveled to the Russian air base in Syria last December to announce a scale-back of the Russian military presence there.
Syria's conflict began with mass protests against the Assad family's decades-long rule. A brutal government crackdown and the rise of an armed insurgency eventually tipped the country into civil war. More than 450,000 people have been killed and 11 million have been displaced from their homes.
Assad's future has been a key sticking point in years of failed peace efforts. The opposition and its Western backers have demanded he step aside as part of a political transition, something the Syrian government has adamantly rejected.
