The UN Security Council has begun discussing a draft resolution on ridding Syria of chemical weapons after the US and Russia agreed the text.
The vote in the 15-member Council could take place later on Friday, say diplomats at the UN in New York.
The agreement breaks a two-and-a-half year deadlock in the UN over Syria.
It is seen as a key step in a US-Russia brokered plan earlier this month under which Syria agreed to disclose its arsenal and eliminate it by mid-2014.
Russia and China have three times blocked Western-backed resolutions in the Security Council against Syrian President Bashar al-Assad.
