THE local plastics industry has taken the lead in establishing a code of conduct, following Governor Chris Patten's call for companies to ensure they were corruption free. In the past three years, about 40 allegations of corruption concerning the plastics industry have been received, with 13 so far this year. The acting assistant director of ICAC community relations, Antonio Chu Lok-sang, said about 30 officers have been deployed to help the private sector develop voluntary codes of practice. ''In the next 12 months, the ICAC officers will invite 429 listed companies and about 200 chambers of commerce and industries to develop their own codes of practices,'' he said. The ICAC received 2,445 corruption reports in the first nine months of this year, a 45 per cent rise on the same period last year. Mr Chu said a code of conduct would enhance a company's reputation for fair and responsible dealing and gave employees a clear idea of what its aims were and how they would be achieved.
