Since the restart of the Franco-German axis by Macron’s assertive initiative to build a strong and self-confident Europe，France’s ambition to reform the EU in a number of domains such as the eurozone and the defense union has been stalled by Germany. Concrete results of Franco-German cooperation are below expectations. The progress of the Franco-German axis has been unsatisfactory because the two countries are still very different regarding their strategic culture，basic ideas on policies，interests，domestic policy and personal character of their leaders. Since Merkel，towards the end of her term of office，became more proactive in foreign affairs，new adjustments and changes have occurred within the Franco-German axis. The author believes that France and Germany are still the closest of allies，and their motivation and spirit of cooperation in European and international affairs exceed their differences by far. They follow similar goals and are supportive of each other. Although the Franco-German axis has encountered challenges from other countries，it is still at the core of the EU leadership and has achieved improved strategic coordination. European integration has always been the outcome of compromises and a balancing of interests. Only when the Franco-German axis moves forward can essential progress be made in the process of European integration.
