Visa rules 'in need of clarification'

Foreigners hoping to visit, study or work in China have a right to know whether the fact that they are carrying an illness could block them at the border, say activists.

The issue arose after a 25-year-old Australian man of Chinese ancestry was refused a student visa.

James Lau said he can think of no reason why the authorities would turn down his application for a student visa other than the fact he has hepatitis B.
