Libya has been stranded in political deadlock since the removal of the former strongman Muammar Gaddafi.
UN-backed PC has been wrestling to impose its authority across the country now administrated by two governments.
Haftar who sides with the eastern government has opposed the PC backed by France, US and several western countries.
France also cooperates with Haftar on counterterrorism. Some French special forces died last year in Eastern Libya in a helicopter crash. The helicopter was operated by Haftar forces.
French Foreign Minister, Jean-Yves Le Drian, who served as Defense Minister in Holland’s government, has been supportive of Haftar, seen as the right ally in the fight against terrorism in the North African country.
