A $100-MILLION Budget grant will help Hongkong athletes' medal hopes at the next Asian and Commonwealth games, the executive director of the Sports Development Board, Mr Howard Wells, said. Mr Macleod pledged in his Budget to give the board the cash to provide training facilities and boost the development of sports science and medicine. Mr Wells said the Government-sponsored board would hold the grant in a trust fund and money would be released periodically to the Hongkong Sports Institute. ''A good deal of attention has been focused by the sports associations and other sports-related bodies towards the next Asian and Commonwealth Games in 1994,'' Mr Wells said. ''The budgets of the board and the Hongkong Sports Institute are being geared towards these targets and this will enable us to strengthen our programme with these games in mind.'' At the 1990 Commonwealth Games in New Zealand, Hongkong won one gold medal in mixed doubles badminton and silver in the men's singles lawn bowls. The Asian Games held in Beijing the same year realised two silvers in wushu and windsurfing. ''The development of sports sciences in Hongkong are very much in their infancy compared to some of the more developed sporting countries, such as China,'' Mr Wells said. Mr Paul Brettell, chief executive of the institute, said: ''Obviously, this kind of initiative from the Government to further sport in Hongkong is warmly welcomed. Extra support for scholarships, science, medicine and supporting services will give coaches and athletes added assistance in training and preparing for major games.'' Mr Macleod also awarded $30 million to help the development of budding performing arts groups on top of $36.68 million that is the annual budget for the Council For Performing Arts. The Sir David Trench fund, which was set up to give small arts groups a helping hand, will award the extra cash on advice from the council. Hongkong's professional and semi-professional arts groups will account for $31 million of the normal budget with just $5.68 million left for small groups. The Secretary for Recreation and Culture, Mr James So Yiu-cho, said experience had proved that the remainder was not enough and led to complaints within the arts community that smaller organisations were not getting a fair deal. He said that the one-off $30 million grant would help the council to plan ahead with them.
