The first Jews to visit Vietnam likely arrived following the French colonization of the country in the latter half of the 19th century. There are a handful of references to Jewish settlement in Saigon sprinkled through the pages of the Jewish Chronicle in the 1860s and 1870s. The 1956 American Jewish Yearbook listed the Jewish population of French Indochina at 1,500, as noted above, but in its 1957 printing, there is no mention of a Jewish population in the region. In 1971, about 12 French Jews still remained in South Vietnam, all in Saigon. In 2006, Chabad opened a center in Ho Chi Minh City, which is considered to be the economic center of Vietnam. A documentary about the Rabbi, Rabbi Menachem Hartman of the Chabad Center was put online by Chabad. The film, (mostly in Hebrew with Russian subtitles) provides a look at the challenges faced by the emissaries upon their arrival, as well as a glimpse of the makeup of the Jewish community that existed upon their arrival. According to the Jewish Telegraphic Agency, the Chabad centre is reportedly used largely by business people and tourists from Israel and the United States, and of as of 2007, there are some 100 Do Thai, or Jews in Hanoi and about 200 in Ho Chi Minh City. According to Hartman, about 10,000 to 15,000 Jewish business people and tourists visit Vietnam each year.
