What are your thoughts on African American/Chinese race relations?

The recent attack in Oakland, California where two young African American men attacked and killed an elderly Asian American man got me thinking, what are your thoughts on African American/Chinese race relations? I live in New York City so I get exposed to pretty much every ethnicity. My mother and grandmother immigrated here close to two decades ago and sad to say, they are rather racist, especially against African Americans. But every race is racist to others in some way, some more subtle than others. As for me, I generally don't listen to what they say about race relations, I have many African American friends at school, not close friends but I wouldn't hesitate to ask them for help. Most of the time they pull the "Asians are smart" stereotype but I let that go because it is in jest. But what about the attack in Oakland? It certainly seems like the elderly man was at the wrong place at the wrong time but then again, I wasn't there so I can never really be sure what happened. My grandmother often says that African Americans are jealous of Asians because they are smarter/more successful but that's just racist rhetoric. Is it a hate crime? I believe that it is racially motivated, even if it is in a small way. That's not to say Asians are not capable of doing the same. I read a few articles but none of them provided any real answer. This whole thing actually gives me a headache thinking about it and I can see why people just refuse to even talk about it! In any case, share your thoughts and please be polite about it.
