South Korea made a clean sweep in the men's events at the Asian Badminton Championships on Sunday, defeating China in the singles and Indonesia in the doubles. China, the prime power in world badminton, won the women's singles and doubles. Seventh seed Park Sung-hwan, who was not even expected to make the final, beat fourth seed Chen Jin 21-18, 21-18 to win the men's singles trophy. “I am so happy because this is the first big title for me ever since I made my international debut six years ago,” said Park, 24. “Maybe this title will give me the boost I need in search of more titles,” said Park whose last major achievement was an appearance in the final of the 2004 Malaysian Open. Park beat Boonsak Ponsana of Thailand in the quarterfinals and then Sony Dwi Cuncoro of Indonesia in the semis. In the second game, Chen trailed 10-17 before drawing level at 18-18. But Park steadied himself, forcing Chen on the defensive as a series of wide shots gave Park the game and the match. The Korean combination of Lee Yong-dae and Jung Jae-sung overwhelmed the Indonesian challenge of Chandra Wijaya and Nova Widianto 21-16, 21-18 to capture their third men's doubles title of the year after the All-England and the Swiss Open. Their latest victory confirmed their status as the hottest pair on the international circuit, with their sights now set on the Olympic gold medal in four months in Beijing. “We are still learning and we still have many weaknesses to iron out. There is still a lot of hard work for us as we head torwards the Olympics,” said Lee. “There are so many other good doubles pair who are competing against us and we cannot afford to let our guards down.” Jung said the strategy was to attack Widianto, believing him to be “the weak link. We were also very patient too, waiting for them to make a mistake.” In the women's singles, defending champion Jiang Yanjiao captured her second ABC crown, defeating China compatriot Wang Lin 18-21, 21-18, 21-13. The world No. 1 women's doubles pair of Yang Wei and Zhang Jiewen continued their supremacy, beating Taiwan's Cheng Wen Hsin and Chien Yu Chin in scores of 22-20, 21
