If you think Snowden leaks was about 'one illegal program' you are seriously misinformed and have a lot of catching up to do. These are large scale and illegal mass surveillance programs. [1][2][3][4][5]. More can be found here. [6]
No one has been held accountable for these illegal programs. The then head of NSA James Clapper brazenly lied to Congress and has still not being held accountable. [7]. On the contrary there is a grand jury out to get Assange, Manning is back in jail and Snowden is being hounded and in exile. No good deed goes unpunished.
China had nothing to do with the Snowden leaks or any of these secret mass surveillance programs as you will discover. Happy reading!
