Mr Reganvanu was responding to calls from the opposition leader in Vanuatu, Ishmael Kalsakau, for the Charge d'Affaires to be expelled in order to send a clear signal to Paris over the Matthew and Hunter islands.
The small uninhabited islands are claimed by both Vanuatu and France which have been holding talks to agree maritime boundaries.
Mr Regenvanu said declaring the French diplomat "persona non grata" is not the right thing to do.
