Arthur Li Kai-yin showed he was still in peak form after his record-breaking performance at the Atlanta Olympics by winning three golds at the Asia-Pacific Age Group Championships in Pusan, South Korea. Li set a new national record in Atlanta three weeks ago with a time of 51.84 seconds in the 100 metres freestyle. The 23-year-old Hong Kong swimmer showed he had not lost any of his form by winning individual golds in the 100 metres, the 200 metres individual medley, and the 200 metres freestyle. Hong Kong won nine golds, seven silvers and six bronzes in the competition, in which the region's leading age group swimmers took part. Snowie Pang, the female swimmer who had a disappointing outing in Atlanta, came back with a vengeance by winning the women's open 400 metres individual medley. Also winning gold was Robyn Lamsam, who won the 400 metres women's freestyle. That made up for some of her disappointment for failing to qualify for Atlanta. Male diver Ng Sui won the boy's under-17 10-metre platform. Team manager Trevor McDonald said more work needed to be done for Hong Kong to continue to be a force in Asian age group competition. 'The swimmers, the coaches and the government would have to put in more effort,' he said. 'We need more competition.' Hong Kong finished fourth overall in the medal standings, behind undisputed leaders China, South Korea and Taiwan. Hong Kong's medal haul included seven silvers and seven bronzes. The territory had 11 fourth-placed finishes at the competition, which ended on Sunday. 'Sherry Tsai set a couple of age group records, and is showing a lot promise in the 11-12 age group bracket,' said McDonald. 'Alan Cheung also swam a couple of best times and took a few fourth places. 'Our younger ones are improving because they are breaking age group records. I don't know how fast the other countries are improving, like Thailand and Malaysia. They weren't swimming as fast as before,' he said. China won 76 golds, 22 silvers and 17 bronzes. South Korea finished the three-day competition with less than half of China's tally of gold medals, getting 35 golds, 59 silvers and 33 bronzes. Taiwan finished on 14 golds, 26 silvers and 30 bronzes. Hong Kong broke one national record, five national age group records, and two Asia Pacific Championship records. The territory's new national record was set by Alex Fong Lik-sun in the 200 metres men's backstroke with a time of two minutes, 10.31 seconds.
