In the West, the decision was made through Treaty of Rome 1957 to launch the first European Economic Community. It shared the Assembly and Court with the Coal and Steel Community, but set up parallel bodies for the Council and Commission. Based on the Spaak Report of 1956, it sought to break down all barriers to trade in a common market for goods, services, labour and capital, and prevent distortion of competition and regulate areas of common interest like agriculture, energy and transport. A separate treaty was signed for a European Atomic Energy Community to manage nuclear production. In 1961 the United Kingdom, Denmark, Ireland and Norway applied for membership only to be vetoed in 1963 by France's Charles de Gaulle.
