A reunion in Hong Kong between a mother forced into exile after the June 4 crackdown and the son she left behind on the mainland almost did not happen when the government refused her entry, the concern group, Homecoming, revealed yesterday. But officials eventually relented and granted her a one-week stay for the visit which occurred five years ago and was only revealed for the first time yesterday. Former student activist Wang Chaohua was allowed into Hong Kong to meet her son on condition she did not appear in public, Homecoming head Reverend Chu Yiu-ming told RTHK. The visit marked the first time an exiled dissident blacklisted by Beijing had been allowed into Hong Kong, Mr Chu said. Ms Wang was in her mid-30s when she became one of the student leaders in the pro-democracy demonstrations in Tiananmen Square in 1989. She was blacklisted by Beijing and fled to the United States, leaving her family behind, including a young son. About five years ago, she arranged to meet her son in Hong Kong. Ms Wang, using a US passport, travelled to Taipei to catch a connecting flight to Hong Kong. But Hong Kong authorities became aware of her intentions. Taiwanese officials told her she would not be welcome in Hong Kong. 'I was surprised to learn about this,' Mr Chu said. 'She was coming with a valid American passport. What the government demonstrated was that Hong Kong was not a city which allowed free entry under the one country, two systems principle.' Ms Wang contacted Mr Chu and he helped set up talks with Hong Kong officials who eventually agreed to let her in provided she made no public appearances. But at last mother and son were reunited. 'When I picked up her son, he said: 'I am not sure if I can remember my mum',' Mr Chu said. The visit marked the first time an exiled dissident blacklisted by Beijing had been allowed into Hong Kong, he said. He added that he wished the Hong Kong government would allow in more exiled dissidents to meet their families, as the city was a convenient place for such reunions. The Hong Kong Immigration Department has previously said it does not comment on individual cases.
