La Chinesca is a neighborhood located in the Mexican city of Mexicali. The location is home to about 15,000 people of Chinese origin, historically the largest Chinese community in Mexico. While this number does not compare to other cities worldwide with a prominent Chinese diaspora, early in the 20th century Mexicali was numerically and culturally more Chinese than other immigrant groups. The Chinese arrived to the area as laborers for the Colorado River Land Company, an American enterprise which designed and built an extensive irrigation system in the Valley of Mexicali. Some immigrants came from the United States, often fleeing anti-Chinese policies there, while others sailed directly from China.
