Economic Corridor was launched. Large investments in Pakistan by the Chinese government have led to a mass immigration of Chinese citizens to Pakistan because of shortage of a skilled workers. But there is also a large number of Chinese who came to Pakistan in 1949 due to fears of Communist persecution. They are mostly situated in Karachi and represent the oldest Chinese in Pakistan after independence. The Chinatown centered on Yaowarat Road in Bangkok, Thailand, was founded at the same time as the city itself, in 1782. Outside of Asia Many Chinese immigrants arrived in Liverpool in the late 1850s in the employ of the Blue Funnel Shipping Line, a cargo transport company established by Alfred Holt. The commercial shipping line created strong trade links between the cities of Shanghai, Hong Kong, and Liverpool, mainly in the importation of silk, cotton, and tea. They settled near the docks, but the area was heavily bombed during World War II, with the Chinese community moving a few blocks to the current Liverpool Chinatown on Nelson Street. The Chinatown in San Francisco is one of the largest in North America and the oldest north of Mexico. It served as a port of entry for early Chinese immigrants from the 1850s to the 1900s. The area was the one geographical region deeded by the city government and private property owners which allowed Chinese persons to inherit and inhabit dwellings within the city. Many Chinese found jobs working for large companies seeking a source of labor, most famously as part of the Central Pacific on the Transcontinental Railroad. Since it started in Omaha, that city had a notable Chinatown for almost a century. Other cities in North America where Chinatowns were founded in the mid-nineteenth century include almost every major settlement along the West Coast from San Diego to Victoria.

The initial Chinatowns were built in the Western United States in states such as California, Oregon, Washington, Idaho, Utah, Colorado and Arizona. As the transcontinental railroad was built, more Chinatowns started to appear in railroad towns such as St. Louis, Chicago, Cincinnati, Pittsburgh and Butte, Montana.
