As for China under-reporting, yes, I think it is quite obvious that the numbers are not exactly correct. I speak daily to people in China for my English lessons and those who are able to speak freely (using a VPN, whatever that it, or some sort of incognito access to the web) tell me that they are very unhappy with their government and know that the numbers are higher and things are not as great as they are making it out to be. I can always tell when someone has some secret access portal to the web as they speak of frustration and anger. Those that access the web, thus my site where I give lessons on a "unsafe" connection always speak- albeit in a strained, almost fake way- of how great things are and what a great job the government did. But it is what it is.
