There is a "story" about from the countries of the former Yugoslavia, about the domestic mafia dealing with trafficking in human organs.
The way: abduction, execution and exploitation of healthy organs ... this is the crime of the worst kind ...

If this is true for China, yes there is work under the leadership of the "chinese communist party" work then it is worse than the mafias ...
How help human?

For Changing behavior the governments - a boycott of any kind of relationship that seems to me almost impossible in today's conditions ...

But I think it would be effective a testimony from China
( should be a condition - must not family stay in China and witness must be out of China).
All dictatorships are sensitive on True about themselves" and the disclosure of truth is always - effectively.
It can even be without a witness if people are afraid for themselves or for their family.

Need is write and record (with a pseudonym without identity), just to turn the attention of the world public and brave politicians who would dare to ask Chinese colleagues about such a topic...
