U.S is blocking Iran’s participation at next month’s planned Syria peace conference but the other delegations have been agreed on and will include other regional players such as Saudi Arabia.
The U.N envoy to Syria "Lakhdar Brahimi" said about 30 nations would be invited to a day of speechmaking planned for Jan. 22 in the city of Montreux, and Iran’s participation was the only sticking point, but was still a possibility. The Syrian opposition also has opposed Iran’s involvement.
Brahimi told a news conference that “our partners in the United States are still not convinced that Iran’s participation would be the right thing to do” , adding “we have agreed that we will be talking a little bit more to see if we can come to an agreement on this question”.
According to Russian deputy foreign minister "Gennady Gatilov" said “we may need additional contacts at the ministerial level in order to clear up the situation around Iran”.
A senior U.S official told reporters on condition of anonymity that Washington objected to Iran’s participation because it hasn’t publicly endorsed the principles from the first Geneva peace conference on Syria in June 2012 .
