"We are trying to calm this conflict down. [The Syrian authorities] should continue interaction with the UN secretary-general's representative in any case," Kosachev told reporters.
According to Kosachev, Damascus maintains that de Mistura must defend the interests of all the participants of intra-Syrian talks, however, he does not hide his preferences and maintains more active contact with certain sides.
"In our opinion, these claims possibly have grounds, though, it is not enough for interruption of the interaction with the UN secretary-general's special envoy," Kosachev added.
On Sunday, an informed source told Sputnik that the Syrian authorities had refused to host de Mistura in Damascus ahead of the next round of talks in Geneva, which are expected to take place on March 23. Damascus did explain the reasons behind the decision.
