If I were an investor and an entrepreneur gave me all these reasons for not entering the Russian or Chinese market, as well as refusing to do business with companies from these countries, I would quickly show them the door.
A good example of the Chinese situation is AMSC: http://www.bloomberg.com/news/2014-02-19/china-supreme-court...
Now, the situation shouldn't have arisen, but as the CEO has observed people thought merely trying to get the Chinese court system to go along with them was nuts. In Russia this would be game over already.
China also has more pro-business and -investment infrastructure than Russia, e.g. well-defended special economic zones, empowered pro-development governance, etc. Bejing has been more stable and predictable in respect of these priorities than Moscow.
After Google left China, their stock went up over time, still much larger than Baidu whose protected market is limited to the mainland.
