Taoiseach Enda Kenny will hold talks today with French president Francois Hollande less than a week on from the Nice terror atrocity.
The fallout from Brexit and security and counter-terrorism measures are expected to dominate discussions at Government Buildings in Dublin.
Eight-four people were killed when Tunisian Mohamed Lahouaiyej Bouhlel drove a truck into crowds enjoying Bastille Day celebrations and fireworks over the Promenade des Anglais in Nice.
Another 15 people remain critically ill in hospitals.
Mr Hollande's trip to Dublin had been arranged before the terror assault and has since been scaled back, but he has retained a commitment to meet President Michael D Higgins.
He will be back in Paris for talks with Prime Minister Theresa May this evening.
The discussions in Dublin will be attended by Foreign Affairs Minister Charlie Flanagan and by Dara Murphy, junior minister for European Affairs.
President Hollande, who has already visited Portugal this week, will be accompanied by Harlem Desir, France's Secretary of State for European Affairs.
