FREEDOM of travel after 1997 will be on the agenda when immigration chief Laurence Leung Ming-yin briefs Preliminary Working Committee (PWC) members in Beijing next week. Mr Leung, the Director of Immigration, will talk to the PWC security sub-group about the right of abode and nationality and will explain the complex nature of the issues surrounding future permanent residency and travel documents. The Government has accepted an invitation from the sub-group for the briefing and will send Mr Leung to attend an 'informal' session. The Government bans formal contacts between civil servants and the PWC. The sub-group's co-convenor, Rita Fan Hsu Lai-tai, had written to the Secretary for Security, Peter Lai Hing-ling, asking him to send an official delegation to brief members on the issues during a meeting in Beijing on April 23 and 24. Mr Leung will hold another round of expert meetings with his Chinese counterpart on the same issues at about the time of the PWC meeting. The Government's thinking is that it might be convenient for Mr Leung to meet the PWC. It regards him as the 'real expert' on the issue. The meeting, however, must be 'informal' and held behind closed doors, a source said. A senior government official said he was optimistic that the two governments would be able to reach an agreement on the issue of right of abode before 1997. A consensus was essential if the two sides wanted to co-operate on the issuing of the Special Administrative Region (SAR) passports, he said. The official said the two sides shared a common interest in finding ways to reduce uncertainty over SAR passports. Mr Leung's briefing will be the second to be given in Beijing by senior government officials to the PWC on transitional issues. Director of Planning Dr Peter Pun Kwok-shing travelled to Beijing in February to reply to criticisms from the PWC economic sub-group on the territory's reclamation strategy. Separately, the Financial Secretary, Sir Hamish Macleod, is to visit Shenzhen on Thursday to improve links over infrastructure and financial development. The Government yesterday announced that Sir Hamish, who is to retire in September, would make a one-day trip to Shenzhen at the invitation of its municipal government. He will be accompanied by the Secretary for Economic Services, Gordon Siu Kwing-chue, and the chairman of the Securities and Futures Commission, Anthony Neoh. The team will visit various infrastructural facilities in Shenzhen, including the Yantian port and Huangtian airport, and the Shenzhen Stock Exchange. Thursday's trip is the third visit by Sir Hamish to the mainland since he became Financial Secretary in 1991.
