The problem is, if at all, in the different view of the economy, of economic growth. Growth is too low, even for us. That needs to change: More investments, a stronger role by the European Central Bank. Otherwise, there are no tensions between Italy and Germany. But on this point, compromises must be reached and we will reach them.

The message that "we can't take in everybody" is imperative. At the same time, the decision as to who has a right to asylum needs to be made in Brussels.

We need to move forward, from the common currency to the banking union to a common financial policy and, in the middle-term, to a common foreign and security policy. That will take time, because we need to figure out how to deal with those countries that don't always want a more tightly integrated European Union.

The route for the refugees currently goes through Greece and the Balkans or through Italy; if there were a crisis in north-eastern Europe, Poland might just as well be affected. In this case we are dealing with mechanisms that we do not control. We need to change that.

We are not perfect. But we have doubtlessly fulfilled our obligations to the EU to a greater degree than the EU has its obligations to Italy, when it comes to the relocation or repatriation of refugees that are in our country. Italy does its homework better than the rest of Europe. Instead of the 160,000 migrants that were to be distributed across Europe, we are currently at 300.

There are differences of opinion, especially when it comes to economic and financial policy. But when it comes to foreign and especially immigration policy, we are in agreement. No other countries in Europe are closer to each other in this regard than Italy and Germany.

But joint pressure from states like Germany, Italy and France could mean a move in this direction. Because something very fundamental is on the line: freedom of movement. I can't think of any common market that could function without it.
