In 1923 the ICRC admitted the first two non-Genevans to its Assembly - Max Huber from Zürich and Motta, who was also the first Catholic.

Motta was involved with the Federal Council Felix Calonder in Switzerland's accession to the League of Nations on 16 May 1920.

In the Interwar Period, he pleaded for a partial departure from Swiss neutrality principle, but spoke out from 1938 in the face of the looming Second World War again for its strict observance.

Annually since 2004, the Geneva Institute for Democracy and Development presents the Giuseppe Motta Medal to people from any country or region of the world for exceptional achievement in the promotion of peace and democracy, human rights and sustainable development.
