Totally agree with the sentiments expressed in this thread. My initial reaction was could this be an Uyghur boy from the Xinjiang region. Genetically the Uyghurs have 60% European ancestry and might account for his European appearance.
Ethnic violence reported by reuters a few days ago. Perhaps this young boy got caught up by the events.

I hope this boy is now safe. Rise up my son and smite the hand of the oppressor.
