The Asian Turf War occurred twice in South Park. The first time in "Child Abduction is Not Funny" in 2002 and second in "City Sushi" in 2011. Both events featured City Wok owner "Tuong Lu Kim".
Background[]
In "Child Abduction is Not Funny", Tuong Lu Kim is asked to build a wall to keep out child predators. The wall is immediately attacked by the Mongolians, sworn enemies of the Chinese who continually destroy the wall surrounding the town.
In the "City Sushi", a new business owned by Junichi Takiyama opens a new sushi restaurant called the City Sushi next to the City Wok. Tuong Lu Kim becomes enraged by his presence to do to the events of the Second Sino-Japanese War (July 7, 1937 – September 9, 1945). The two restaurateurs attempt to settle their differences with a "Tower of Peace" when Tuong Lu Kim betrays the trust and murders Junichi by throwing him off the Tower of Peace and covering it up by claiming it was suicide.
