China business is entering a new era: On the one side, business environment has been changing in uncertain direction: Geopolitical tension and lasting China-US trade war produce their shadow on future business development. Companies have to become more lean and agile to cope with the increasing risks in domestic and international markets. On the other side, digitization of the economy is continuing its path of growth also in this second largest economy of the world, which brings new opportunities for companies to increase efficiency and achieve more competitive advantage in a smart way. The 2019 Sino-German Controlling Forum has the leading motto: "Controlling 4.0: Efficiency and Digitalization". It aims to provide a platform of information, communication, and experience sharing among both business decision makers and controllers who would like to improve efficiency of their business and controlling practice in a world of increasing uncertainties.
