China Girl (1987) on Netflix

In a New York City dance club, a teenage Chinese girl, named Tyan "Tye" Hwa (Sari Chang), meets and dances with a teenage Italian boy, Tony Monte (Richard Panebianco), much to the consternation of the many other Chinese and Italians in the club. Tye's protective older brother, Yung Gan (Russell Wong), and his friends chase Tony out of the club and through the streets. Tony makes it to Canal Street, the dividing line between Little Italy and Chinatown, and thinks he is safe. After some hesitation, the Chinese gang crosses the border and chases Tony through Little Italy. When Tony runs into an alley and finds a locked gate, it looks like he is about to be beaten with bats and chains. Just then, Tony's older brother, Alberto "Alby" Monte (James Russo), and his friends show up. A fight ensues, but police arrive and everyone runs away.
