It looks more like it might be the human slave trade, rather than asylum seekers, it has similar connotations to previous incidents and it appears these poor devils may have originated from the same area in China where the cockle-pickers (Morecombe bay)and the previous ones that died in a lorry (20 years ago) came from.
It was mentioned somewhere recently that in the last 15-20 years China's economic growth has helped to lift something like 100m people out of abject poverty, but clearly not in the region where these people came from!
