Most of the Internet links wordlwide go through the US, so it makes
sense for US intelligence to tap it there (see recent AT&T taps with
As a Tor exit relay is an opportunity for tapping traffic, it makes
perfetc sense for China to setup Tor exit relays and gain competitive
advantage in analyzing that part of the network traffic.
China does not route a significant portion of internet traffic, it has
no foothold in any of the key data exchanges worldwide. Setting up a few
hundred exit relays in mainland China gets you instant insigth into
sensitive traffic worldwide.
(by the way, China could also set up exit relays in the US and
everywere, it's cheap)
Let's see if the design of Tor can cope with a challenge of such a scale.
My guess is that countries like China would rather be better served by
not disrupting the Tor network (with misleading exit policies,

reach the Tor network themselves.
I would like the torproject website to be more explicit warning users
