The National Coalition and other opposition groups have not receive formal invitations to Geneva II, Russian Foreign Minister Sergei Lavrov said.
"We are concerned about the fact that there is some game going on with invitations to the opposition. The latest thing we could find out is that the coalition and other opposition groups have not received formal invitations to Geneva II yet," he told a press conference in Moscow on Friday.
Lavrov said it is obvious that "the [UN] secretary-general is waiting for the coalition to make a decision on whether it will go to Geneva or not."
Lavrov said it is especially important that both representatives of the Syria opposition in emigration and internal patriotic opposition forces should be represented at Geneva II.
Lavrov said he is hoping that the UN secretary-general will take this condition into account when sending out invitations to the conference.
"We are convinced that the secretary-general and the UN in general have a complete picture of the situation with the conference, will draw the right conclusions, and will send out the needed invites to ensure that the entire range of Syria's opposition forces is represented at Geneva II," he said.
