Sometimes there is genuinely no way to find the perp, but a lot of the time, either the police are cowed into not really investigating too hard (when the perp turns out to be the son of a highish ranking government official, or wealthy business family, for example), or there is this kind of attempt to make things go away by paying-off the victims, police and anyone else necessary.
I would guess (but you never know) Huawei itself may have little involvement, other than providing the salary required to drive such an ostentatious vehicle, etc, in what is still a poor, developing (though thoroughly corrupt) nation (http://i46.photobucket.com/albums/f135/gavinmac/15181532_346...)
