About 200 Chinese students demonstrated in Beijing Tuesday against "hooliganism" and for women's rights after an African man allegedly accosted a Chinese woman in her dormitory.

The protest march and a subsequent class boycott marked the third time since Dec. 24 that tensions between Chinese and Africans have provoked fights or demonstrations in China.Last week, thousands of Chinese in Nanking demonstrated against African students following a Christmas Eve fight that began when the Africans tried to bring Chinese women into a dance.
