China child trade: Father won't give up search for son

An illegal market in children has developed in China, in which babies are being openly sold online.

Police say many of the victims are from the estimated 20,000 children abducted each year - a crime with a devastating impact on separated children and parents.

Xiao Chaohua's son, Xiaosong, disappeared in 2007 - he says he will never stop looking for him.
