As many as 300 African students boycotted classes Wednesday at a Beijing college to protest anti-African unrest in China as racial tensions continued on Chinese campuses for a second week.

African students at colleges in Nanjing, where the first protests erupted last week, were also reported boycotting classes in fear of their safety if they return, foreigners in Nanjing said.The African students at the Beijing Languages Institute stayed out of class in an organized strike the day after a protest by Chinese students on the campus claiming African students had harassed young Chinese women there.

African and other foreign students at the college said several hundred Africans had dropped a plan to stage a counter-demonstration Wednesday morning, but were staying in their dormitories to protest the continued racially oriented campus unrest.

"We're very worried about this," said one African student, who declined to be identified. "We have no guarantees for our safety."

A spokesman for the institute said 300 African students are registered there, accounting for a fifth of the 1,500 Africans studying at Chinese colleges. The students said nearly all appeared to be staying out of class.

About 200 Chinese students marched on the campus Tuesday carrying banners and distributing leaflets protesting a New Year's Eve incident in which an African student allegedly accosted a Chinese female student in her dormitory.
