POLICE superintendents will go to China in October to try to win assurances on command autonomy after 1997 in an effort to persuade senior officers to stay on. About 20 officers are expected to join the talks and routine inspections in Beijing. It will be the first visit for such a high-ranking delegation. Superintendents' Association chairman Milly Stradmoor said precise dates and meetings had not been arranged. She said members had concerns about Chinese sovereignty but added it would be inappropriate to reveal them. 'We are looking for better liaison and understanding. Hopefully, some of our members' worries will be answered. Getting direct feedback from the Chinese will probably help some of our undecided officers to make a decision soon.' The visit follows the release late last month of the force's manpower planning survey. It revealed a large proportion of officers above the rank of senior superintendent, the most critical command tiers, were either undecided or were leaving before 1997. Only 57 per cent of the top 150 officers said they would serve beyond 1997. However, despite the figures - and the suspicion some police fudged returns because it was not confidential - Deputy Commissioner (Management) Peter So Lai-yin has insisted the force can cope. Overall, 11 per cent of the 2,493 officers above the rank of inspector were undecided about serving after 1997. Only 173 - or 6.9 per cent - indicated they would definitely leave the force. About 82 per cent of police, mainly inspectors with little chance of alternative employment, have no plans to quit before 1997.
