This news from Hong Kong: Chinese pro-democracy dissident Chai Ling voiced concern today about the future of freedom in Hong Kong and urged the People’s Liberation Army not to repeat the 1989 massacre of protesters in Beijing. Chai was one of the student leaders who spearheaded the 1989 democracy movement in Beijing’s Tiananmen Square. He was in Hong Kong for a short visit, held a news conference, when asked to comment on moves by Hong Kong’s post-handover leader Tung Chee-hwa to curb civil liberties. Tung unveiled his plan to limit protest rights and ban foreign funding of political groups last month. The curbs would take effect on July 1, after Britain hands its 156-year-old colony back to China as a quasi-autonomous capitalist region.
