Lin Dan's China will look to reassert its dominance in badminton ahead of the Olympics by resuming its stranglehold on the Thomas and Uber Cup titles on home ground from Sunday. The sport's pre-eminent nation suffered a blip at the last Thomas Cup in 2014 when Lin's team was stunned in the semifinals by Japan, which then beat Malaysia in the final. But Japan axed star man Kento Momota in April over a gambling scandal, and the signs are that normal service will be resumed when the world team championships convene in Kunshan. China's men won the Thomas Cup five times in a row until its defeat to Japan, while its women have collected eight of the last nine titles in the concurrent Uber Cup. Uppermost in its minds will be the Rio Olympics in August, where China will attempt to match its performance at the last Games where it swept all five gold medals. "China always makes a strong point to prove their strength in team matches," Raphael Sachetat, chief editor of the online magazine badzine.net, said. "Players always give their best for their country and this will be especially true for the men's event." Lee Chong Wei could be one stumbling block. The Malaysian star, who led Malaysia to the 2014 final, beat both Lin and top-ranked Chen Long to win the Badminton Asia Championships earlier this month. Winning the Thomas Cup would be a significant boost for Lee, 33, as he aims for a still-elusive gold medal in Rio. But experts warn that pressure is already mounting on the veteran as he gears up for the Olympics — after losing the 2008 and 2012 finals to his nemesis, Lin. "The pressure is on Lee Chong Wei to deliver the nation's first ever (Olympic) gold medal," Rizal Hashim, a Malaysia-based sports analyst, said. China will have an early chance for revenge against Japan in Group A, where it will also play France and Mexico, while Malaysia faces South Korea, England and Germany in Group C. In Group D, second-seeded Denmark is drawing inspiration from Japan's 2014 run as it takes on Taiwan, New Zealand and South Africa. "If Japan can win the Thomas Cup, I think we can win as well," fifth-ranked Jan O Jorgensen of Denmark told the Badminton World Federation website. "Two years ago was an eye-opener for many teams." In the Uber Cup, defending champion China is favorite to secure its 14th crown with three former world number ones, including Olympic champion Li Xuerui, at their disposal. However Japan's Nozomi Okuhara, and top-ranked doubles pair Misaki Matsutomo and Ayaka Takahashi, could cause them problems, as could Thailand's world No. 2 Ratchanok Intanon. "Japan will be their main threat, led by Nozomi Okuhara, who has beaten top Chinese players recently and (has) very strong women's doubles," said Sachetat. Both competitions feature 16 teams divided into four groups, with the top two in each qualifying for the quarterfinals.
