EUROPE: Paris, 13 – A decision of major importance in the history of postwar Europe was taken today at a session of the Organization for European Economic Cooperation. All the free countries of Europe, with the aim of putting an end to the need for receiving aid from the United States, drew up a program of trade agreements that are based entirely on their own resources. A total of 17 countries, including Greece and the free zone of Trieste, set up their own economic organization and unanimously approved a plan which was characterized by the US delegate, Mr Draper, as marking the dawn of a brilliant, peaceful economic period for Europe.
