Police have asked their counterparts in Macau and Guangdong to help monitor the movements of protesters coming to Hong Kong for the WTO conference in December. The move was revealed after the Director of Crime and Security, Senior Assistant Commissioner Tang Hau-sing, and fellow officers met their Guangdong and Macau counterparts at the police headquarters in Wan Chai yesterday. 'Hong Kong has requested Guangdong and Macau to help us, provide timely intelligence and also to co-operate on the operational side,' Mr Tang said. 'Given that this is a large conference, many people from overseas will come to Hong Kong. Some may not come through the mainland or Macau. We hope [our counterparts] can help monitor the situation.' Meanwhile, Eastern district councillors yesterday warned there could be trouble if the government barred protesters from leaving Victoria Park in Causeway Bay, which officials intend to designate as a protest zone during the World Trade Organisation conference. While most of the councillors accepted using the park as a gathering point for protesters, they felt the crowd - expected to be 10,000 strong - could cause trouble if the police stopped them from marching to locations closer to the conference venue, the Convention and Exhibition Centre in Wan Chai. The council members, who were briefed about the conference arrangements yesterday, were also concerned about traffic disruption during the meeting, to be held between December 13 and 18. The police promised they would deploy enough officers to maintain order and public safety. The head of the government's co-ordination office for the conference, Janet Wong Wing-chen, said they would meet the Hong Kong People's Alliance on WTO - which was co-ordinating protests - today to discuss the arrangements. WTO representatives from Geneva would also attend the meeting for the first time, Ms Wong added. The district council was also told yesterday that the commander for Eastern police district, Chief Superintendent Choi Wong Fung-yee, had been personally involved in two WTO-related anti-riot exercises.
