Russian President Vladimir Putin and US President Donald Trump agreed a joint statement on Syria on Saturday that said they would continue joint efforts in fighting ISIS until it is defeated and that there was "no military solution" for the war in Syria, the Kremlin said.
The Kremlin said the conversation between Trump and Putin took place on the sidelines of the Asia-Pacific Economic Cooperation (APEC) summit in the Vietnamese resort of Danang.
It said the statement on Syria was coordinated by Russian Foreign Minister Sergei Lavrov and US Secretary of State Rex Tillerson especially for the meeting in Danang.
The White House did not immediately respond to questions about the Kremlin announcement.
Putin and Trump confirmed their commitment to Syria's sovereignty, independence and territorial integrity and called on all parties to the Syrian conflict to take an active part in the UN-led peace talks in Geneva, the Kremlin said.
Moscow and Washington agree there is no military solution to the Syrian conflict, according to the text of the joint statement published on the Kremlin's website.
Television pictures from Danang showed Putin and Trump chatting - apparently amicably - as they walked to the position where the traditional APEC summit photo was being taken at a viewpoint looking over the South China Sea.
Earlier pictures from the meeting show Trump walking up to Putin as he sits at the summit table and patting him on the back. The two lean in to speak to each other and clasp each other briefly as they exchange a few words.
Although the White House had said no official meeting was planned, the two also shook hands at a dinner on Friday evening.
