The president, who arrived the Nnamdi Azikiwe International Airport, Abuja, in a Nigerian Air Force helicopter, immediately boarded his presidential jet to continue the journey to Iran.
It would be recalled that a statement issued by Presidential spokesman, Mr Femi Adesina, on Friday, said that Buhari and other GECF leaders were expected to review the current market outlook on gas and discuss strategies for boosting gas production.
Nigeria and other GECF members currently account for 42 per cent of global gas production, 70 per cent of global gas reserves, 40 per cent of pipeline transmission of gas and 65 per cent of the global trade in Liquefied Natural Gas.
While in Tehran, the statement said President Buhari will hold bilateral talks with other participating Heads of State and Government on the sidelines of the summit and meet with the Nigerian community there.
Accompanying the president on the trip according to Mr. Adesina are the Ministers of Foreign Affairs, Mr Geoffrey Onyeama; Power, Works and Housing, Mr. Babatunde Fashola; Minister of State for Petroleum Resources, Mr Ibe Kachikwu and the National Security Adviser, Maj.-Gen. Babagana Monguno (rtd.).
President Buhari is expected back in the country on Tuesday, November 24.
