I think that China government may choose to boycott for any reason. German government assholes in charge getting involved reduces the cost of boycott to China assholes in charge. Discrimination, boycott in this case, always has a price. Here the preferred supplier is discriminated against leaving only higher priced or inferior suppliers allowed to do business with Chinese government assholes. Fine if they want that. Not fine for German asshole government to subsidize China government discrimination against another party. In so doing they are party to the act. It is a restraint of trade and cartel behavior from German government assholes. They are the problem. Chinese assholes want to discriminate and pass the cost of assholery making them cheap-asses. German assholes agreeing to subsidize the cost to Chinese assholes are dumb-asses.
