I do wonder if they were making fun in a mean way or just poking fun in good nature. Of course, the person experiencing it is the one who can better tell, but it is often not obvious when lacking cultural context. One of my closest friends early on laughed at me because whenever I pronounced "vehicle" it sounded to him as "bagel", it did hurt my ego but I quickly got he meant nothing bad by it.

That said, if the American students were really making fun of the accent of Chinese students in a mean way, I can only assume they themselves never tried speaking any kind of Chinese. It is insanely difficult to get to "understandable" in a tonal language if your native language is not tonal, let alone "without funny accent".
