The production of natural resources in agriculture, forestry and fisheries, stable natural hydrological cycles, fertile soils, a balanced climate and numerous other vital ecosystem services can only be permanently secured through the protection and sustainable use of biological diversity.

Economically and politically, Germany is extremely stable. There are countries with functioning governments whose institutions don't work. My only concern is about Europe. There's a risk we will run out of time. We have been blessed with a pro-European French president, but we are also approaching the next elections for the European Parliament in 2019, and it will be important for pro-European parties present a credible answer to the anti-Europeans on the left and the right.

Less and less is the question being asked as to whether developments are taking place in a democratic and free way. Europe is in a phase in which this output is no longer sufficiently visible or tangible. Youth unemployment is still far too high, we still haven't solved our currency problem and living conditions in Europe are drifting apart. That is one reason why critics say that our Europe is based on yesteryear's model.

The truth is that we have long had a multi-track Europe with very different objectives. The traditional differences between the north and the south in fiscal and economic policy are far less problematic than those that exist between Eastern and Western Europe. In the south and east, China is steadily gaining more influence, such that a few EU member states no longer dare to make decisions that run counter to Chinese interests. You see it everywhere: China is the only country in the world that has a real geopolitical strategy.

It is clear that Germany needs a foreign policy in which we jointly define European interests. Thus far, we have often defined European values, but we have been much too weak in defining mutual interests. To preempt any possible misunderstandings: We cannot give short shrift to our values of freedom, democracy and human rights.

Madame Merkel knows very well that her conservative Christian Democratic Union or CDU, and the CSU, the Bavarian sister party to the CDU, with which it shares power nationally, must change their European policies. The FDP's nationalist-liberal position on Europe is presumably one of the reasons the attempt failed to form a Jamaica coalition government which would have seen the CDU, FDP and Green Party govern together.

I hope that a German foreign policy in 2028 will be part of a European foreign policy, because even the strong country of Germany won't really have a voice in the world if it is not part of a European voice.
