Yeah, an interesting observation is that, while China already have sites like techweb/donews/cnbeta that supply IT news from all over the world in Chinese, there are not as many English sites/blogs that can do the same for China-related IT news.
Mobinode is a good example and I hope we'll see more in the future.
What you described is indeed true and I do hope things will change at some point. However, I can easily list several reasons why Chinese companies don't target foreign market...
Please keep up the good work. I believe that, even without foreign presence, some of these Internet companies in China deserve to be heard by the outside world.
