All China has to do is say is  Taiwan you are free to go and we can all be friends.  Let Hong Kong be free too, as its peoples desire  it . A trade war or a real war helps no one. China has been a bully and picks on  small countries and that is shameful and harms China. I do believe Trump will defend Taiwan at all costs-Taiwan is a friend, a democracy,  an ally and a great  role model for China to pursue,  if the bloody minded Communist Party can ever see the light.
