& you really think, a boycott would do any good?
Anyway, it's not true that investment in China necessarily destroys employment in the investing country (a claim on your English webpage). By producing in China companies can perhaps create greater revenue, which may actually save jobs in these companies.
The PRC is some kind of dictatorship, the Human Right situation is bad, a.s.o., but a boycott wouldn't change very much. What might have an effect would be a worldwide import ban on Chinese products. How realistic is that?
What's more, if you'd do that, a lot of international companies (many of them Japanese) would lose their investments in China. Who would compensate them? Don't you think, that this would lead to even more job losses? Maybe some companies would have to declare bankruptcy.
