There are no jews in China. I wonder why.

Jews and Judaism in China have had a long history. Jewish settlers are documented in China as early as the 7th or 8th century CE, but may have arrived during the mid Han Dynasty, or even as early as 231 BCE[1]. Relatively isolated communities developed through the Tang and Song Dynasties (7-12th cent. CE) all the way through the Qing Dynasty (19th cent.), most notably in the Kaifeng Jews (the term "Chinese Jews" is often used in a restricted sense to refer to these communities). By the time of the establishment of the People's Republic of China in 1949, few if any native Chinese Jews were known to have maintained the practice of their religion and culture. In the late 20th and early 21st centuries, however, some international Jewish groups have helped Chinese Jews rediscover their heritage.

In the 19th and early 20th centuries, Jewish immigrants from around the world arrived with Western commercial and quasi-colonialist influences, particularly in the commercial centers of Shanghai and Hong Kong, which was for a time a British colony. Tens of thousands of Jewish refugees escaping from the 1917 Russian Revolution and the Holocaust in Europe were to find sanctuary in China in successive decades.

Today, with the current expansion of trade and globalization, Jews of many ethnicities from multiple regions of the world have settled permanently and temporarily in China's major cities.
