World Disarmament Conference
From 1930, Massigli was intimately involved in the preparatory work for the World Disarmament Conference scheduled to open in 1932. The increasing divergence between German demands for "Gleichberechtigung" ("equality of armaments") (abolishing Part V) and the French demand for "sécurité" ("security") (maintaining Part V) together with the strains in Franco–German relations imposed by the attempt at an Austrian-German customs project of 1931 left Massigli increasing disillusioned with the Weimar Republic. In 1931, Massigli advised the Premier Pierre Laval before his summit with the German chancellor, Heinrich Brüning, that France should offer a bailout for the collapsing German bank system only if the Germans were prepared to forgo the demand for "Gleichberechtigung" at the upcoming World Disarmament Conference. Brüning refused the French conditions at his summit with Laval.
