Fears are rising that an influx of mainlanders would push the unemployment rate up and stretch social security services to the limit. Democratic Party legislator Law Chi-kwong warned yesterday that children arriving without their mothers would place a heavy demand on social and security services. He urged officials not to overlook the need to allow mothers to continue to arrive on one-way permits. The Legco welfare representative also suggested giving migrants the choice of returning if they felt Hong Kong was not the right place for them. 'I imagine some might just want to ascertain their right of abode without settling here,' he said during a briefing by government officials on the Court of Final Appeal ruling on right of abode. Ronald Arculli, Liberal Party vice-chairman, said officials could explore the idea of creating an 'outpost' in Macau or Shenzhen for eligible mainlanders to relieve Hong Kong's burden. 'This is not a joke. The Government really needs to open its mind to consider some new possibilities,' he said after the meeting. Hong Kong General Chamber of Commerce representative James Tien Pei-chun said the industrial and business sectors were concerned if adult migrants would be an asset to society. 'We know nothing about their education level and skills. How are we going to provide them with jobs?' he asked. The Democrats' economic spokesman, Sin Chung-kai, estimated the jobless figure would rise to 10 per cent if tens of thousands of unskilled mainland adults arrived. Legislator Lau Chin-shek of the Confederation of Trade Unions said the Government should not focus on just education or welfare needs. 'Many of them are no longer kids. I hope the administration would not overlook the importance of providing job opportunities,' he said. Secretary for Security Regina Ip Lau Suk-yee said the demographics of the eligible children would be studied. 'We've got to be realistic and establish priorities. How can we absorb so much in one go?' she asked. In a statement issued yesterday, the Bar Association urged the Government to give unqualified support and commitment to the court ruling. 'The Government should not just accept but also be seen to fully embrace and respect the final ruling of our highest court. 'The rule of law should never be compromised by what may probably be mere near-term practical but nonetheless onerous difficulties.'
