 Well, because the world is developing as it is with a lot happening in the international political field. And it's obvious for us who looks at these changes, how they actually changes the preconditions to reach sustainable development. So what's happening in China for example, how China is in the last three or four years much more active in the international scene. How what we've seen in the United States with Trump looking much more inward. Of course this changes the global playing field and has a lot of implications for choices to steer towards sustainable development.
