Hariri is now in Paris, where he met French President Emmanuel Macron on Saturday.
Lebanon's Saad Al Hariri, who announced his resignation as prime minister on Nov.4, has arrived in Cairo for talks with Egyptian President Abdel Fattah Al Sisi, Egyptian state news agency Mena and Hariri's press office said on Tuesday. In a televised interview last week from his home in Riyadh, he said Hezbollah's support of Iran against Saudi Arabia was a threat to Lebanon's stability.
Also on Tuesday, Aoun made a phone call to Sisi where they discussed "the developments of the political conditions in Lebanon", according to a statement from the Egyptian presidency.
"Lebanese politics has always been defined by competition and cooperation between sects", said Faysal Itani, a senior fellow at the Atlantic Council's Rafik Hariri Center for the Middle East.

McMaster joined the Trump administration in February following the ouster of former National Security Advisor Michael Flynn. McMaster said Kushner had no business being in the White House and shouldn't be involved in matters of national security.
Saad Hariri has returned to Lebanon for the first time since his shock resignation as Lebanon's prime minister more than two weeks ago.
Hariri, a long-time ally of Saudi Arabia, left Lebanon on November 3 and announced his shock resignation from the Saudi capital the next day, accusing Iran and the Hezbollah militant group backed by Tehran of destabilizing his country.
Hariri, a long-time ally of Saudi Arabia, cited fear of assassination and meddling by Iran and Hezbollah in the Arab world in his resignation speech.
Hariri's arrival in Cairo coincided with the arrival of the Egyptian president from a two-day visit to Cyprus where he attended a tripartite summit with Greece.
