Poroshenko arrived in France on an official visit earlier in the day.
"Of course we regret this visit, because it is no use to discuss with Mr Poroshenko because he doesn't make any effort to calm the situation in eastern Ukraine," Aymeric Chauprade, a member of the right-wing National Front party, said.
Chauprade added that France and Germany are still trying to reach an agreement with Ukraine, having participated in Minsk talks on the country's reconciliation.
In February, the leaders of Russia, Ukraine, France and Germany convened in Minsk and created a package of agreements on Ukrainian reconciliation. The deal, signed by the representatives of Kiev authorities and independence supporters, stipulated ceasefire, withdrawal of heavy artillery from the line of contact and prisoner exchanges, among other points.
