International organisations often rely more heavily on English. Younger diplomats are more likely to prioritise it in their training.

This shift places French in a competitive position. It must justify its continued use alongside a more universal lingua franca.

Perceptions of French as elitist or outdated

Despite its historical prestige, French can carry an image of exclusivity. Some view it as a relic of aristocratic Europe or as a language requiring years of specialised study.

These perceptions can discourage learners and reduce their appeal in multicultural, fast-paced diplomatic environments.

Initiatives include expanding Francophonie programmes, funding language training for diplomats, promoting French-language education abroad, and increasing the availability of multilingual digital tools.
