BEIJING - The Chinese government has permanently lifted a 20-year old ban on entry of foreigners with HIV/AIDS, sexually transmitted diseases and leprosy, as well as narrowed the restrictive scope for mentally ill and tuberculosis patients to only "severe mental patients" and those with infectious tuberculosis.
There are also pragmatic reasons for the revision, which comes days ahead of the opening of the Shanghai World Expo. The government had previously lifted the ban temporarily for various large-scale events including the 2008 Olympics and the 1995 World Conference for Women.
The government has realized that the ban has had limited effect in preventing the diseases in the country and has instead caused inconvenience for the country when hosting international activities.
