UN envoy Lakhdar Brahimi has said progress at the Syria peace talks has been slow but can form a basis on which the two sides can build, as he closed the week-long conference in Geneva.
He said he had seen a "little bit of common ground" between government delegates and the opposition.
Syria's Foreign Minister Walid Muallem, however, said there had been no tangible results from the conference.
Another round of talks has been scheduled for 10 February.
The opposition has agreed to take part, but Mr Muallem refused to commit.
"We represent the concerns and interests of our people. If we find that [another meeting] is their demand, then we will come back," he told reporters.
