Even prior to the armistice of 11 November 1918 the AMTC had been making preparations for changes to introduce in the event of fighting ceasing.
By 13 November, two days after the armistice, the British government proposed to their counterparts in France, Italy and the United States that the AMTC be transformed into a "General Economic Council".
After discussion amongst the parties involved an agreement to set up the Allied Supreme Council of Supply and Relief was reached on 12 December 1918, with the organisation holding its first meeting on 11 January 1919, a week before the actual Paris Peace Conference opened.
