The story of Chinese settlement in Kolkata goes back to the late 18th century when one Tong Achew set up a sugar manufacturing unit to the south of the city. Although the sugar factory closed down, the workers moved to the city proper. Scholars researching on international migration have written tomes about why Chinese immigrants settled in Calcutta (as the city was then known as). Through enterprise and hard work, the Chinese people soon integrated themselves into the city’s cosmopolitan framework. Initially, they settled down in the central part of the city (old Chinatown) and then some of the families shifted to the eastern fringe (Tangra, new China town).
