The Chinese bimbo program had had a rough start, their government had declined to test it on their own citizens, even the criminal.  To move it beyond virtual tests they had gone abroad to find raw materials to use, like this early test model.

It had limited success as by the time the programming was complete they only spoke Mandarin and were completely subservient to any man they encountered. 

Of course, once they had proven it was possible, the government had opened up more raw material from them to work on.
