Just as we can't tell the difference between a German, a
Scandinavian, and a Russian, and an Irishman by sight alone, the
Americans can't tell the difference between a Chinese, a Japanese,
a Vietnamese, even Mongolian.
After 911, a Sikh in USA was killed, because he wore a turban, and
was thought to be an Arab.
To the untrained eye, there is this cliche: "They all look alike."
