Anti-Chinese racism even seems to have traction among those who would abhor racist comments about black people. I recently heard a senior academic ask a group of his colleagues whether Harrow (an area of north London) is 'how the Chinese say "hello"'. The same academic later proposed to the same group that Chinese students might be attracted to his institution if they were allowed to watch episodes of the 1970s Hanna-Barbera animation Hong Kong Phooey. I somehow couldn't imagine the same individual joking about calypso songs and bananas in the same carefree manner.
It is possible to see such phenomena as evidence of a resurgence of Sinophobia in recent years, correlating with the emergence of China as a global superpower. But it is also useful to remember that they are part of long tradition of colonial derogations of China (and Asia in general), as John Kuo Wei Tchen and Dylan Yeats's new book Yellow Peril!: An Archive of Anti-Asian Fear demonstrates. The book is a very useful sourcebook containing examples of well-known (e.g. the Fu Manchu franchise) and lesser-known cultural texts in which 'Chineseness' is demonized, as well as a wide range of anthropological and historical writing about Western Sinophobia from the Middle Ages to the present day. I highly recommend it for students, scholars and anybody with an interest in why public discourse about China has become so debased.
