Which could leave the bugs with star billing at Bangkok's chilly Thammasat University pool. At the last Games, in the Japanese city of Hiroshima in 1994, seven Chinese swimmers tested positive for steroids, including two newly crowned world champions. The scandal upstaged the Games and brought accusations that the world's news sporting superpower had embraced East German-style systematic doping. More doping rows followed until at this year's World Championship four Chinese swimmers tested positive for steroid-masking agents and another was caught with human growth hormones in her baggage. But Chinese officials insist they are taking the doping fight seriously. As Tu Mingde, secretary-general of the Chinese National Olympic Committee, told the South China Morning Post this week, winning is no longer all that counts. "Winning 100 gold medals or more is not everything for China," Tu said. "What matters most is that we have come here to win cleanly." "We are exercising a strict policy which involves strict prohibition, strict testing and severe sanctions on any athlete caught taking drugs," he added. Some of China's top swimmers will be missing out on the Asiad, including world record holders He Cihong and Le Jingyi, as well as butterfly specialist Liu Limin. But China, which recently announced Beijing's bid to host the 2008 Olympics, should still grab the lion's share of the medals. Their campaign will be led by world record holders Chen Yan and Wu Yanyan -- who both set astonishing world records at the 1997 National Games in Shanghai. The strongest competition will come from Japan, whose line-up includes 16- year-old Ayari Aoyama, a former short course world record holder in the 100 metres butterfly, and backstroker Mai Nakamura. Thailand's Rattapong Sirisanont, who was awarded two golds in Hiroshima after seeing his Chinese rivals disqualified, will be carrying the hosts' hopes. First, however, Games organisers have to solve the problem of nightly bug invasions. Thousands of insects attracted by the bright lights of Bangkok have been dropping in for a dip at the Thammasat pool -- forcing organisers to set up special "pest control units". "The biggest problem comes in the evening when there is a plague of insects," said Major-General Kamol Saen-issara of the Thai swimming association. - --- Checked-by: Patrick Henry
