What was the Chinese's role in the plot to kill Bill the Butcher in Gangs of New York? There are various scenes where Amsterdam is talking to the Chinese in charge of the venue where the natives hold their annual celebration of The Priest's death and it is apparent that the Chinese are willing to help.
Amsterdam: The chinks hated the Natives even more than the Irish.
Also, prior to Amsterdam unsuccessfully killing Bill, Amsterdam looks over to the Chinese and he has disappeared, presumably taken by Bill's men.
So what was his role in the plot to kill Bill the Butcher?
