Action groups plan to send a delegation to Indonesia to study the violence against ethnic Chinese. The groups, headed by members of the Democratic Party and the April 5th Action Group, said yesterday they wanted to speak to witnesses and victims of alleged rapes during May's riots. The groups are angry about Jakarta's denial of the rapes and have called on Beijing to withhold billions of dollars in loans until an independent probe is carried out. Democrat Albert Ho Chun-yan said the groups wanted to meet Indonesian diplomats as soon as possible to seek permission to send a delegation. 'We want the delegation to meet members of the Chinese community in Indonesia and get a better understanding of the situation,' he said. 'We want to gather evidence or perhaps even get testimony from witnesses or actual victims of the violence.' But another group warned interviewing the victims could be ill-advised. Joe Law Pui-kwan of the Women's Christian Association, which held a candlelit vigil outside the Indonesian Consulate in Causeway Bay last night, said many victims of the violence might still be too distressed to talk about their nightmare. 'We would like to go and speak with them but we have heard they are quite upset. Speaking with them could upset them further,' Ms Law said.
