China Girl (1987) on Netflix

Plot summary

Tony Monte works at a pizzeria, and Tye lives in Chinatown with her brother Yung Gan. They meet in a New York City dance club, to the consternation of the Chinese and Italians there. Yung Gan and his friends chase Tony through the streets to Canal Street, the line between Little Italy and Chinatown, and across it. Tony's older brother Alby arrives with friends, a fight follows, and police break it up. Alby tells Tony to stay out of Chinatown, and Yung Gan orders Tye to keep to her own neighborhood. A Chinese restaurant, the Canton Garden, has opened in Little Italy, and Yung Gan's gang demands weekly protection money from its owner. Tony later comes into the alley below Tye's fire escape and invites her to meet him at a subway station.
