ANGRY exhibitors blamed a lack of organisation for the disappointing turnout at the International Investment Expo '93. The four-day event, which featured a combined exhibition of investment and trade, money, real estate, and franchising, ended yesterday at the Hong Kong Convention and Exhibition Centre. Claims by some participants that attendance was less than half of the estimated 13,000 visitors who toured the exhibition last year were rejected by event organiser, Adsale Exhibition Services. Adsale marketing manager Law Chi-po said suggestions that there was a sharp drop in the number of visitors this year were not well founded. ''The exhibition has been well received this year,'' he said. ''We think the number of visitors will be very close to the levels recorded last year.'' Mr Law said a record of the number of visitors had been kept at the entrance to the exhibition but declined to say what the figure was. ''It is too early to release the attendance figures,'' he said. ''We will not have the final figure until we have the chance to check the official registration numbers.'' Mr Law said reports that numbers were down could in part be because at the event last year, forex exhibitors brought along large teams of salesmen and their presence had made the expo look busier. ''The franchising and money exhibitions have been the most popular displays for visitors this year,'' he said. The exhibition attracted 50 organisations from 15 countries. Real estate exhibitor Austwide PRD, which reported an excellent sales turnover at the exhibition last year, said the attendance level was extremely disappointing. Managing director Freddy Poon claimed fewer than 3,000 people had come to the exhibition on Wednesday, Thursday and Friday. ''The dissatisfaction with the attendance level is fairly widespread. I know some exhibitors will be complaining to the organisers,'' he said. Other real estate agents from England and Australia also reported a disappointing result. Better results were recorded from the Money '93 exhibition, which included displays by the Stock Exchange of Hong Kong, the Investment Fund Association, Hong Kong Futures Exchange and the Securities and Futures Commission, who were all given free booths by the event organisers. ''It's been a worthwhile exercise,'' said SFC public affairs and policy manager, Patrick Leung Pak-lit. Hong Kong Futures Exchange marketing manager Judy Cheng Shui-yee said although the exhibition had been quiet, it had been a valuable opportunity to introduce new investors to futures and options trading.
