Democratic Party chairman Martin Lee Chu-ming said PLA troops could allay fears over their presence by behaving themselves. 'I hope the PLA would show that they are law-abiding soldiers so as to boost Hong Kong people's confidence in them,' he said. 'I hope they would do a good job so Hong Kong people would welcome them.' Although the party did not see the necessity of having Chinese troops stationed in Hong Kong, it raised no objection to the move because it was provided for in the Joint Declaration. He said the troops would have to abide by both Hong Kong laws and PLA garrison laws. The Frontier's Emily Lau Wai-hing said no more troops should be sent to the territory before the handover. 'We were told earlier that the PLA troops would only come after the handover. How come they arrived earlier than everyone expected? 'I hope they will not have any high-profile activities here, such as walking outside in full military uniforms . . . it will scare people,' she said. Secretary for Constitutional Affairs Nicholas Ng Wing-fui said: 'Whether more troops will be coming, depends on the need.' But he said the first batch was necessary because they had to discuss transitional arrangements.
