CHINA and Britain are still negotiating over whether the PLA can enter the territory before midnight on June 30, Governor Chris Patten said yesterday. 'We obviously want to ensure that the Chinese garrison arrives in the most efficient way,' he said. 'I am sure there will be a resolution because both sides want to see it handled in a low-key . . . sensible way.' His comment followed a Chinese-language newspaper report that China wanted to deploy 2,000 troops and 20 armoured vehicles in Hong Kong on the afternoon of June 30 to step up security before the arrival of Chinese leaders for handover ceremonies. Some 200 PLA troops are already here as an advance party. But Chinese officials said more troops should be deployed so they could begin their duties at midnight. Speaking after visiting the Police Training School, Mr Patten said the PLA advance troops had behaved well. 'There has been one incident which I think everyone regrets, but . . . the PLA troops in Hong Kong have scrupulously followed all the regulations and arrangements which were put in place a few months ago,' he said. Prime Minister Tony Blair raised Britain's concern over the swearing-in ceremony for the provisional legislature with G-7 leaders on Friday. Mr Blair discussed his concern that Japanese officials were likely to attend the ceremony - which is being boycotted by Britain and the US - with Japanese Premier Ryutaro Hashimoto.
