The relations among France, Germany and Great Britain played a key role in the process of European integration. Early on after the Second World War, the basic policies of France towards Germany were to dismember and weaken it. Soon after, the prologue of the Cold War was ensued as the alliance between the U. S. and the former Soviet Union collapsed. The Cold War put West Europe onto the forward position, the Soviet Union replaced Germany as the supreme menace to France, and Germany served France as the protective screen to the threat of the Soviet Union. Under this international situation, the Franch policy towards Germany transformed from hostility to reconciliation. On the other hand, the split of Germany dispelled France’s alert mind for the moment and laid realistic basis for their reconciliation. As a result, in 1950s, the reconciliation between France and Germany was achieved and the political basis for post-war European integration was laid down. In 1960s, France vetoed twice the proposal of Britain for the entry of European Community, the reasons being as follows: First, the French president Charles de Gaulle doubted the determination of Britain for its economic integration into the Common Market, and doubted its determination of abandoning traditional policies and the British Imperial Preference|Second, President Charles de Gaulle was reluctant to accept Britain before the accomplishment of Common Agricultural Policy for European Community|Last and the most important, the initial conceiving of President Charles de Gaulle was to establish ″Europeans’ Europe″ led by France and centered in France and Germany. The fundamental objective of President Charles de Gaulle was to regain a great power status for France in Europe and even in the world, and obviously, Britain was the key force to drag Europe into the track of the Atlantic Community led by the United States. Until late 1960s, when West Germany’ economic and political strength boosted distinctively, and the Common Agricultural Policy have been shaped up, President Georges Pompidou decided to accept Britain as a member of the European Community to balance the German power. The conflicts between France and Britain led to the ups and downs of Britain concerning its late entry into the European Community (also the expanding of the European Community) for more than ten years. In the late 1980s and early 1990s, in the context of the collapses of the former Soviet Union and Eastern European countries as well as the unification of Germany, the European Community countries headed by France paid special attention to Germany’s promise of sticking to the Europe integration. To be specific, the position of Germany towards the Economic and Monetary Union (EMU), especially towards the negotiation time-table of the EMU, was the wind vane. After repeated negotiations and running, at the special Summit in Rome in 1990 of the European Community, the attending countries reached an agreement with Germany to the time-table issue of EMU. In December 1990, France and Germany put forward a joint proposal concerning the political union. Consequently, the France-Germany cooperation was of crucial importance for the signing of the Maastricht Treaty and strengthening of the European integration.
