In a final declaration the Arab League summit said it "affirmed that the Golan is occupied Syrian territory according to international law, the decisions of the United Nations and the Security Council," France24 reported.
A separate statement dedicated solely to the issue called Washington's move "invalid and illegitimate".
"It is true that America is the strongest military force in the world, but its decision is absolutely worthless," League Secretary General Ahmed Aboul Gheit told a closing news conference.
