"It is impossible to hold talks on either the Syrian political process, or on such an urgent and important matter as a ceasefire, without having a common idea of who are terrorists in Syria and who are opposition forces," Zakharova said in the statement.
Russia's approach to resolving the Syrian crisis will remain the same, Russian Foreign Ministry spokeswoman Maria Zakharova said in a statement on Tuesday.
"Recently, some media, citing statements from some [of our] foreign partners, reported that Russia had changed its stance on the Syrian issue. In this regard, we would like to clarify the matter of Russia's approach to Syria… We haven't changed it [our policy] and have no intention of doing so," Zakharova said in the statement.
Syria has been engulfed in a civil war since 2011, as Syrian government forces fight opposition factions and extremist groups, including Islamic State (IS, or Daesh in Arabic), outlawed in Russia, and the Nusra Front.
Since September 30, Moscow has been conducting airstrikes on terrorist positions in Syria at President Bashar Assad's request.
