Interesting! I plan to eventually do long-distance cycle touring. I would love to see a lot of other countries, including a good number in Asia. Between the pollution and police-state, however, I just don't have any interest in visiting or cycle-touring in China.
Not only does such tourism support a government which has repeatedly proven itself inimical to the concept of individual civil rights, that same government is an environmental catastrophe. Given the known pollution levels, I figure I may as well take up cigarette smoking again as try to even cycle there, much less race! It sounds like just breathing is bad enough.
