They sure look more Indonesian than Chinese to me.

Most South-East Asians have larger eyes. My vote would be northern China/Korea.
Does the first guy have a turban on...the second pic sure looks Indonesian to me too.
I'm sorry, but I can't tell their ethnicity by those pics....(and why would they call them Chinese if actually a different ethnicity?)...but it seems that Indonesians would be more likely to attack us than the Chinese, in that they have many muslims.
