Hong Kong star Chai Po-wa's participation in the Olympic Asian qualifying tournament, on home ground next year, is still in doubt. It was announced yesterday that the SAR will host the regional qualifier, sponsored by the Cosco Group, at Queen Elizabeth Stadium from February 29 to March 5. However, it is uncertain if Chai, who is now studying a pre-university course in Xiamen, Guangdong province, would be available for the event. 'I hope that she will compete. We'll talk to her soon,' said Hong Kong Table Tennis Association chairman Tony Yue Kwok-leung. Yue added that they would announce the squad, comprising five men and five women, before the December 15 application deadline. Chai had been one of the best players in the world during her prime. However, she has never returned home with an Olympic medal, although she took part in the two previous Games in Barcelona and Atlanta. She pulled out of the SAR's Asian Games squad last year after discovering she was pregnant. Yue said he hoped Hong Kong could achieve the same number of qualifiers as they did for Atlanta, when they were represented by two men and three women, including Chai. Mainland import Wong Ching is the only Hong Kong athlete to have booked a place in Sydney so far. Meanwhile, organisers believe the qualifier will boast a star-studded lineup as top players who have qualified in the singles must compete here if they want to be selected for the doubles as well. Top Chinese players include Olympic champion Liu Guoliang and his doubles partner, Kong Linghui.
