Moussa, addressing the Arab Economic Forum in Beirut, said Parliament Speaker Nabih Berri's call for dialogue "cannot be rejected."

"The persisting vacancy in the presidency is a very serious issue," Moussa said.

"I did all I can to solve the Lebanon crisis. The crisis, however, is not incurable," he insisted.

Moussa said there is "consensus on several points," stressing the need to implement the Arab League plan designed to end the political impasse.
