"We were unable to come to a common understanding over who to include in the list of state sponsors of terrorism, which is why we developed the term 'regional forces supporting terrorism'."
Jafari underscored Syria's opposition to funding and providing logistical support to extremist factions by foreign powers.
"It is illegal for armed groups to be trained and sponsored by countries like Saudi Arabia, Qatar, Iran, Turkey, Israel, Jordan and others."
Jafari added that delegates representing Syrian leadership and its fragmented opposition failed to unanimously adopt the 12-point program despite having agreed on all but two of the points.
Several extremist groups, including the Islamic State and the Nusra Front, have taken advantage of the Syrian conflict dating back to civil unrest in 2011. ISIL in particular has captured vast parts of the country and established a violent form of fundamentalist rule in territories under its control as far back as 2012.
The United Nations estimates over 220,000 people have died in ongoing fighting and millions more have been displaced.
