Russia circulated on Friday a draft UN Security Council resolution to authorize the deployment to Syria of up to 300 more unarmed ceasefire observers and hopes that it will be put to a vote in the coming days, council diplomats said.
There are seven monitors already in Syria after the council authorized an advance team of up to 30 on Saturday.
A new resolution is needed for a further "initial deployment" of up to 300 as recommended by U.N. Secretary-General Ban Ki-moon.
Some council members, however, have expressed reluctance to give swift approval for an expanded observer mission because of concern about the failure of the Syrian government to halt the violence, return troops to barracks and withdraw heavy weapons.
"I can confirm Russia just circulated a draft," a council diplomat told Reuters on condition of anonymity.
"Not yet clear when the vote will be."
He added that it could be voted on over the weekend, though another envoy said the vote would most likely he held next week.
"There's a (council) meeting now at the Russian mission to discuss the draft," a diplomat said.
The 15-member Security Council has been divided between Western countries that want to topple Syria's President Bashar al-Assad and Russia and China, which support him and have twice vetoed council resolutions condemning Assad.
But on Saturday Russia and China joined the rest of the council in voting for a resolution to authorize the deployment of the first batch of UN monitors.
It is unusual for Russia to draft a Security Council text.
Russia has only recently begun drafting council resolutions on issues like piracy in Somalia, the conflict in Libya and the crisis in its ally and top weapons customer Syria.
In Moscow, Russian Foreign Minister Sergei Lavrov said on Friday: "We should do everything we can to adopt, as soon as possible, a second resolution that will approve a full-scale observer mission."
French Foreign Minister Alain Juppe told a French news channel on Friday that France was also drafting a resolution designed to allow a larger observer force to be deployed in Syria with up to 500 observers as well as helicopters.
