Police yesterday tightened security around the Convention Centre and Grand Hyatt where President Jiang Zemin is staying and where today's celebrations are to be held. Hundreds of people plan to stage protests there and across the territory. Police have received 11 protest applications from various groups. Most roads at Wan Chai waterfront have been sealed off, with unauthorised vehicles prohibited from stopping and security checks in place. A temporary command post has been established near the hotel and barriers have been set up around the area. The marine police have deployed more boats to patrol the harbour, with divers also conducting underwater security checks. Yesterday, human rights groups including Amnesty International Hong Kong and Human Rights in China lodged a petition at the Central Government Offices calling for the abolition of the death penalty. Eight members from Greenpeace staged a street show at the Star Ferry Pier in Tsim Sha Tsui to highlight the stark contrast between Hong Kong and Chinese authorities on regulation of genetically engineered foods. But about 2,500 people yesterday took part in a parade, from Central to Wan Chai, organised by the pro-Beijing Hong Kong Federation of Trade Unions. 'It has been a great achievement for the SAR Government to put the concept of 'one country, two systems' into practice,' federation president Cheng Yiu-tong said.
