CHINA is producing more graduates with language skills while Hongkong's language standards have remained ''disappointingly low'', according to a language campaigner and major employer. The chairman of the Hongkong Language Campaign, Mr Brian Renwick, said China could have the edge in business through its language skills and reduce Hongkong's post-1997 importance. Mr Renwick, who is also senior personnel manager for the Hongkong and Shanghai Banking Corporation, said it was ''worrying and depressing'' that Hongkong students still underestimated the importance of language. Some tertiary institutions had reported students were ''not interested'' in English language skills. ''We need to continue to put the pressure on to convince them it does matter because if you want to see a future for Hongkong it is, as in the past, in international trade - and this depends largely on English for communication,'' he said. The Hongkong Language Campaign symposium on April 1 will draw together government, education and business groups to discuss the problem and developments in language teaching and training. Delegates to the International Business Committee meeting on February 18 have already expressed concern over the low standard. China emphasised language skills and was producing results.
