Though with the "economic reform" and the unstoppable information flow with internet, China has become something really weird unlike anyone else in the history. Nobody believes in communism and everybody knows the government is lying all the time and yet just lives with it. Every activity by the government is for money and mostly quick money (for the officials).

I don't even think the hackers in this matter care much for the information. They may just try to get more funds from the government. Sometimes they even frame somebody or fake a threats to get the money. The funds will always be granted in such a situation because "if you don't grant you put the country in danger" and "if you grant you can take the commissions".

Most of the time every bit of it is simply dirty corrupted business. Many of the officials' children are permanent residents in the US. Some of them are even already citizens.
