Iranian Oil Minister Masoud Mir Kazemi welcomed his Lebanese counterpart Gebran Bassil to Tehran to discuss potential joint developments in the energy sector.
Kazemi said both sides agreed to discuss Iranian gas exports with Iraqi and Syrian officials during an upcoming meeting in Iran.
Baghdad in August agreed to the terms of a pipeline that would deliver Iranian gas to Syria through its territory.
The pipeline could carry around 3.8 billion cubic feet of gas per day through Iraq.
Kazemi added that Lebanon was keen on joining forces with Iran on a long-term basis, the Iranian Oil Ministry's Petroenergy Information Network reports.
"Lebanon is interested (in benefiting from) the scientific and technical capacities of Iran's oil industry in the construction of gas pipelines and oil refineries," the Lebanese minister was quoted as saying.
