In my experience, most south east asians do not find black men attractive for reasons beyond physical attraction.
Unfortunately, because of stereotyping, many asian families usually tell their children to expect criminal behaviour from black people. But also, fair skin is generally considered more appealing in many asian cultures, dark skin is perceived as dirty or lower class. This applies even to the darker skinned among the asian community. Also, education is a big thing for many asian families as again because of stereotyping, black men are not expected to be very educated.
In many instances, even if an asian girl likes a black guy, there may be very little chance of that translating into a long term relationship because of family pressure.
