German Finance Minister Wolfgang Schaeuble and new French counterpart Bruno Le Maire said they are setting up a working group to produce proposals for a planned bilateral summit in July. Germany and France could either propose a joint corporate tax system of their own or concentrate on pushing ahead efforts for a harmonized assessment basis for corporate tax at the European Union level, Schaeuble said. Le Maire's opening comments to a joint news conference were in fluent German, saying there needs to be better coordination of economic policy.
