Jean Monnet's initial contact with Dwight Morrow was through the Allied Maritime Transport Council (AMTC), established in 1917, in which Morrow was involved. This Council was later absorbed into the new Supreme Economic Council in 1919. Monnet was the French representative in the Council's supply section. Morrow and the Dulles brothers, John Foster and Allen were also involved with this Council. Morrow's relationship with Monnet continued because of their interest and participation in the world of banking and finance. Monnet upon his resignation from the post of Deputy Secretary General of the League of Nations, got together a consortium, which included Morrow and John Foster Dulles as lawyer to negotiate a Polish loan in 1927 and in 1928 did the same for Rumania
