With the planned meeting just hours away, the five permanent members of the United Nations Security Council have not yet agreed on a draft resolution on an international bid to settle the conflict.
The resolution endorsing a two-year road map for talks between the Syrian government and opposition on a unity government is to be presented to the UN Security Council.
This comes as Iranian Foreign Minister Mohammad Javad Zarif, who is in New York to attend the talks, said two issues remain unresolved ahead of the negotiations.
He said the parties still do not see eye to eye on a list of opposition groups that should be included in the peace process, nor have they agreed on a list of terror groups.
