During the meeting in Beirut on Tuesday, Jannati said the security and stability of Lebanon meant that of Iran.
He stressed Iran’s support for convergence and dialogue among all Lebanese political groups to enhance security, stability and peace in the country.
Berri, for his part, said that Iran was still concentrating on the issue of Palestine with a special zeal and tried to safeguard the unity within the Islamic world and protect the territorial integrity of all regional countries.
He also expressed the hope that Iran’s nuclear agreement with the world powers would be signed soon so that all regional countries, including Lebanon would benefit.
In December, Iranian Parliament Speaker Ali Larijani underlined Tehran's support for unity and solidarity among the Lebanese groups, and welcomed the recent talks between Hezbollah resistance group and al-Mustaqbal movement.
"Presidency in Lebanon is an internal issue and other countries can only help this trend, but we certainly support any point of reliance for Lebanon's unity and consider the recent talks in Lebanon between Hezbollah and al-Mustaqbal as a good event," Larijani said, addressing students at Lebanon's School of Law.
He praised Lebanon's resistance against the Zionist regime, and said, "This is a major point and advantage for the Lebanese people who bear the flag of resistance as it showed a new approach to the Muslim world and the Islamic states which had been discouraged and disappointed for years were awakened by the Lebanese people, and this is a great honor for this nation."
Larijani underscored Lebanon's influential role in the region, and said Tehran and Beirut have long had close and strategic relations, and ensured that the same trend would continue.
