According to Reuters, multinationals Total and Peugeot are among the most high profile companies to have signed new deals since the accord that provided sanctions relief for Iran and dozens of smaller French firms have also moved in or are looking to tap the Iranian market.
According to an invitation sent to companies by the Medef business group, officials from the Foreign Ministry, Finance Ministry and France's business office in Tehran will offer on Tuesday an "analysis of the consequences of the non-certification" by Trump of the accord.
European capitals are determined to keep the accord alive and the Paris government wants to know how its companies might react to the US move.
"We're still assessing how firms are reacting to the Trump decision, but we are trying to not be overly alarmist with them," said a French diplomatic source.
While Trump did not pull the United States out of the agreement, he gave the US Congress 60 days to decide whether to reimpose economic sanctions on Tehran that were lifted under the pact agreed between Iran and six world powers.
Since the deal was agreed, however, France has maneuvered to deepen economic ties with Tehran and has repeatedly said it believes Iran is fully implementing the nuclear accord.
According to a notice on Medef website, the discussion points include an explanation on the next steps at the US Congress, the position of the accord's other signatories — Britain, France, Germany, Russia, China and the European Union — and the immediate consequences on companies already operating in Iran.
