The summit of the Dôme is marked as lying entirely within France on the French Institut Géographique National (IGN) map , although on Italian Istituto Geografico Militare (IGM) map the summit appears to lie on the frontier between France and Italy. In June 2015, Italian Prime Minister Matteo Renzi expressed repeated claims on the territory. The Swiss National Map, which covers the massif at 1:50'000 scale, shows both disputed areas around Mont Blanc and Dôme du Goûter in a neutral way, after previously following the French interpretation of the border until 2018.
