THE Independent Commission Against Corruption (ICAC) yesterday promised a greater exchange of intelligence and more working meetings with Chinese officials to further co-operation in the fight against cross-border corruption. And a special education group could be formed aimed especially at teaching Hong Kong businessmen how to avoid bribery while on business in Guangdong. The announcements were made by ICAC Commissioner Bertrand de Speville on his return from a 10-day official visit to Guangdong and Beijing. ''The work on investigation co-operation will involve a series of meetings over the next few months to explore ways and means of improving operational liaison, for instance, on the exchange of intelligence and mutual referral of corruption complaints,'' he said. Complaints this year were at their highest level since 1975. In the first nine months of this year, the ICAC received 2,445 corruption reports, 169 more than for the whole of last year. Before Mr de Speville's visit, he said the figures were worrying, but also showed that society was not prepared to tolerate corruption. Mr de Speville visited the Guangdong Provincial People's Procuratorate in Guangzhou, the Guangdong Provincial Higher People's Court, and Guangdong's Public Security Department and Juvenile Reform Institute. Accompanied by ICAC acting Director of Operations Tony Kwok Man-wai, Director of Corruption Prevention Tony Scott and Director of Community Relations Eddie So Chuen-yee, he also had talks in Zhuhai, Shenzhen and Beijing, where he visited various government departments and the Supreme People's Procuratorate. Discussions were held on anti-corruption strategy and international issues, including China's application to host the seventh International Anti-Corruption Conference in Beijing in 1995. Mr de Speville said he hoped future discussions through the working meetings would consider proposals such as the publishing information on China's anti-corruption laws. Fight Crime Committee member Justein Wong Chun welcomed the proposals. ''We will see a greater number of corruption cases [in the run up to 1997] and it is time for both Hong Kong and China to put their heads together. ''But they must tackle the Big Brothers of corruption cases rather than the small fry. This will increase public awareness and drive home the anti-corruption message,'' he said. This week the ICAC arrested 24 people and charged six, one a senior immigration assistant, in connection with what it claims is one of the biggest known forged passport syndicates in Hong Kong.
