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.

As long as a certain problem primarily affects a different country, in this case Italy, one might not put it at the very top of one's list of priorities.

We have a strong military deployment in Iraq and Afghanistan. In countries like Syria, we need a diplomatic breakthrough to end the war. In Libya, the country must first of all be stabilized to stop IS. This means supporting the Libyan government, including in terms of security. We don't want to repeat the mistakes of the past in that country. The situation is extremely dangerous and the next days could be decisive.

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.

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.

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.

It is ridiculous to believe that Greece might be taking in one million migrants, registering them, then giving refuge to those who have a right to asylum and sending everyone back that does not. Greece is not doing that. We can blame the Greeks for that, but at the same time we should change the Dublin Regulation. When we insist on this unrealistic procedure, it means nothing more than that we are defending Dublin while renouncing Schengen.
