German Finance Minister Wolfgang Schaeuble said on Friday that it was not just up to Germany to help Greece, saying this was a task for the whole of the euro zone. "We are aware of our responsibility and we will do everything to do justice to this responsibility but this is not just a responsibility for one country, not just a responsibility for Germany … It's a responsibility for the euro zone as a whole," he said after a meeting of the finance ministers and central bank chiefs of the Group of Seven countries.
