The Economic and Monetary Union was established more than 20 years ago. While achieving remarkable success，it has also experienced the test of the 2008 financial crisis and sovereign debt crisis after 2008. Due to the inherent institutional defects in the initial of European construction project and the divergent economic models of member states，the euro zone countries lack an effective mechanism to deal with external shocks. In order to correct these systemic defects，the European Union commits itself to reforms oriented towards federalization and stability，especially via the ambitious “French version” blueprint launched by President Macron，which could function as final solution to address the imperfection of the euro. But the success of this plan largely depends on the consensus of the French-German duo and the trust of European citizens.
