Beside this I work - together with Jens Rosenke - on a longer paper about Chinese military espionage. This will take a time, but we come along a few interesting aspects, e.g. an assessment of Chinese real military requirements and a new calculation of the number of possible spies, controlled by Chinese institutes in Germany.
Till then you can watch a video showing the way Chinese spies are relaxing after work, taken at the Chinese embassy in Berlin:
(Unfortunately Blogger can´t spin the video. You see here a line of windows in the upper floor. In the middle there seems to be the gym > a guy is using the bycicle..)
