The first Chinese immigrants to Mexico came from China, some were Philippine-born Chinese, brought by the Manila-Acapulco galleon trade [citation needed]. However most contemporary Chinese immigrants came to Mexico during the 20th century as contract workers and political refugees. With the rise of anti-Chinese sentiment in Mexico in the 1930s under President Plutarco Elías Calles, most Chinese Mexicans, including individuals of mixed Chinese and Mexican descent, were forced out of Mexico and deported to China.
