Police may take the unorthodox step of calling up groups they fear could demonstrate unlawfully outside this month's World Bank-International Monetary Fund meetings. Chief Superintendent Tang King-shing said no notification of plans to demonstrate had been received. But he was aware that at least one group had voiced its intention to do so. Opponents of the conference yesterday said they planned for their actions to be peaceful. They intended to notify the police, but would go ahead with or without the 'notice of no objection' required by the controversial post-handover Public Order Ordinance. Mr Tang said police wanted to take a reasonable approach with protesters 'so that they are able to achieve their objectives in a lawful manner', while ensuring 'the need for public order and safety'. 'If the groups do not notify us, we may take the initiative,' he said. May Wong of the group Solidarity Against the World Bank and the International Monetary Fund pledged that demonstrations would go on. 'We oppose the ordinance, but our main purpose is not to challenge the law or the Government. 'We just want to let [Hong Kong people] know about the World Bank and the International Monetary Fund. 'We want to say they are not helping the poor and the Third World countries develop, but are making the poor poorer and the rich richer.' Ms Wong, and fellow activist Tam Chun-yin said they were from a coalition of local and foreign groups, which ranged from Christian organisations and the April 5th Action Group to Britain's Socialist Workers' Party. They have told the more radical members to protest peacefully, especially since overseas groups may not know of the changes to the public order rules. 'We don't want to give the Government the excuse to suppress us,' Ms Wong said. About 1,500 officers will be involved in security operations at the World Bank-International Monetary Fund meetings, which will be held from Monday to September 25 at the Convention and Exhibition Centre. A private company has been contracted to provide additional security inside the venue.
