The Syrian ambassador to the United Nations, Bashar Jaafari, will head the government team in peace talks due to open in Moscow on Monday, a pro-government newspaper reported.
But the delegation will not join the talks until Wednesday, after two days of preliminary discussions among opposition participants, the Al-Watan newspaper reported.
Ahmed Arnus, a top adviser of Foreign Minister Walid Muallem, will be among six other members of the delegation.
"Opposition figures will meet together from Monday before the Syrian Arab Republic delegation joins them on Wednesday," the paper said.
"It is a consultative meeting to prepare the ground for a dialogue which will be held later in Moscow or Damascus."
The main exiled opposition alliance, the National Coalition, has announced it will not attend the Moscow talks, although some of its members are attending in a personal capacity.
"Any talks should be held in a neutral country and overseen by the United Nations," a Coalition source said, alluding to Moscow's strong support for the Damascus government.
Five Coalition members, including Ahmed Jarba, a former leader seen as close to Saudi Arabia, are attending in a personal capacity.
Members of opposition groups tolerated by the Damascus authorities are also travelling to Moscow.
