What is the true danger to navigation is the constant calls the Chinese military make on 121.5 telling aircraft to get of their airspace. That is sometimes a long way from China when you can see the Philippines, Vietnam, Taiwan, Korea, or Japan etc out the window.
They just take take take, no consideration for the rule of law most of the time.
