I looked for the meaning of "exotic" in Spanish today, and I found that we can use it to refer to something or someone who come from a far place or unknow for us. However, some people thinks that call someone exotic is raicist. I don't think it's raicist because the meaning doesn't have anything discriminatory. It's probably the languagues change the meaning of some words or I also think more the culture has influence the meaning of words... That's my humble opinion.
