Israeli Prime Minister Ehud Olmert said tonight there was a "revolutionary change" in the perception of the Arab states towards Israel, Israel's YNet news website reported.
YNet quoted Mr Olmert saying during a reception for his Kadima party faction: "There is a process here that the fighting in Lebanon [last year] has sharpened.
"This process has brought the influential countries in the Arab world to realise that Israel is not the biggest of all their troubles. This is a revolutionary change in their perception."
Arab leaders had earlier endorsed a 5-year-old plan offering Israel normal ties with all Arab countries in return for its withdrawal from land seized in the 1967 Middle East war, the creation of a Palestinian state and a "just solution" for Palestinians displaced in 1948 with Israel's creation.
Mr Olmert described the summit as a "serious affair".
