"With a $2 Billion Factory From China, a German City Lets Others Worry." News adds: "Arnstadt’s embrace of a giant new battery plant for electric cars illustrates Europe’s ambivalence toward Chinese investment: Jobs trump geopolitics." 

Again, despite historical facts and current trade relations, naysayers abound in regards reportage of dealings between the world's biggest economies. Negativity is the nickname of today's journalism? Trade facts: Germany is China's biggest trading partner and technology exporter in Europe, and the amount of German investment in China ranks second among European countries, after the United Kingdom. China is Germany's largest trading partner, superseding the United States since 2017. 

  China/Germany. Truth is, Chinese and German relations, albeit high and low, aren't new. These countries formally established BFFhood in 1861, when Prussia and the Qing Empire signed the first Sino-German treaty during the Eulenburg Expedition. Ten years later, the German Empire was founded and the new state inherited the old Prussian treaty. That time though, the friendship got cold. Germany joined imperialist powers like Great Britain as France carved out influence in the Chinese empire. Remember, the Germans were also part of a Western alliance that tried to crushed the Boxer Rebellion in 1899 to 1901. 
  After World War I, relations improved as German military advisers assisted the Kuomintang government's National Revolutionary Army. However, when Adolf Hitler forged Axis friendship with Japan in the 1930s, Germans and Chinese weren't cool again. Then after World War II, Germany was split in two states: a liberal democratic West Germany and a communist East Germany. Cold War led to West Germany's alliance with the United States vs communism per se. The East hooked up with the Soviet Union and China. But after the German reunification in 1990, sweet relations between Germany and China was again alive. 

  So are the Germans "worried" about Chinese money coming in a.k.a. investments? Let's just say that is a global fact which could be difficult to fathom. Like, many Filipinos, despite our blood as mostly Chinese than Europeans etcetera, still view the Chinese negatively. Ask South Americans like Brazilians, Bolivians, or Argentinians. Not so good. Yet their governments openly embrace Beijing's money. While some 84 percent of the Chinese view Germany positively, only 20 percent Germans are cool with China, says a BBC survey. Yet the fact is: Germany turns to China for business. By 2014 German Chancellor Angela Merkel had visited China on trade missions seven times since assuming office in 2005.
