Rouhani due in Paris as Iran drums up business with French
Among them is a likely agreement with French aircraft manufacturer Airbus for more than 100 new aircraft.
Mr Rouhani will also meet French President Francois Hollande.
Mr Rouhani`s five-day visit to Italy and France is the first by an Iranian president in nearly two decades, as the Iranian president seeks to rebuild economic ties and secure new trade deals.
Iran is likely to need hundreds of new aircraft in the coming years as it re-establishes commercial air travel restricted by the sanctions, and French carmakers will once again be free to supply to the Islamic Republic.
As well as a deal for Airbus planes, contracts are likely to be signed with car manufacturers Peugeot and Renault, Mr Rouhani told reporters on Monday.
