Syrian opposition chief Ahmed Jarba is "very interested" in travelling to Moscow to meet officials from the Russian government, an advisor to Jarba told AFP Sunday.

Russia invited National Coalition president Jarba to Moscow from November 18 to 21, which would have coincided with a visit by representatives from the Syrian government, said Munzer Aqbiq.

But the opposition head "regretted" being unable to visit Moscow on Monday, due to "preset official commitments", the adviser added.

"President Jarba received an invitation from Russian Foreign Minister Sergey Lavrov for an official visit to Moscow for talks", he said.

Jarba "expresses a high interest in the Coalition for relations and talks with Russia as well as his interest in visiting Moscow", Aqbiq said.

The comments come a day before a Syrian government delegation is set to arrive in Moscow.

Moscow and the Coalition will "coordinate ... a new date for a visit," Aqbiq added.

A Damascus official had earlier this week said the government delegation will be made up of the Syrian president's advisor Buthaina Shaaban, Deputy Foreign Minister Faisal Muqdad and Ahmad Arnous, the ministry's senior official on European affairs.

Their visit is set to take place ahead of a proposed peace conference on Syria dubbed Geneva II, that aims to bring government and rebel representatives to the negotiating table.

The opposition Coalition has agreed to attend peace talks in Geneva.
