Even a G7 Summit may make little difference. The first such gathering took place in 1975 (to be precise, it was a G6 summit because Canada was overlooked). Since then, summits have often been held in rather predictable locations: London, Paris, Venice, Toronto, Munich. Sometimes, however, nations decide to “do a Cornwall”, with summits held in locations that could do with a bit of extra investment. Did the summits make any difference? Campania, Liguria, Abruzzo and Sicily are four Italian-hosted G7 locations. Relative to Europe as a whole, they’re all poorer than they once were.
