A repeat of the last two men's Olympic finals was confirmed after Lin Dan and Lee Chong Wei both progressed to the last four at the Badminton Asia Championships in Wuhan today.
China's Lin, who got the better off his Malaysian rival at both Beijing 2008 and London 2012, comfortably came through his quarter-final in front of his own fans.
The number two seed and defending champion saw off South Korea's Lee Dong-keun, 21-15, 21-11.
Lee, ranked third, proved too strong for Chinese Taipei's Chou Tien-chen, 21-16, 21-18, to set up a meeting with his rival.
In the remaining quarter-finals, China's top seed Chen Long ousted Indonesia's Tommy Sugiarto 21-16, 21-14.
The double and reigning world champion will meet his compatriot Tian Houwei, after the fifth seed eventually got the better of Chinese Taipei's qualifier Wang Tzu-wei, 21-15, 19-21, 21-16.
In the women's competition, China's Olympic champion and top seed Li Xuerui booked her place in the last four thanks to a 21-17, 21-19 win over Tai Tzu-ying of Chinese Taipei.
She will meet South Korea's Sung Ji-hyun who accounted for Japan's Sayaka Sato, 21-15, 16-21, 21-13.
India's Saina Nehwal also remains in the frame after she ended the hopes of China's number three seed Wang Shixian, 21-16, 21-19.
That set up a semi-final clash with home hopeful Wang Yihan, who recorded a 8-21, 21-13, 21-19 success over Japanese second seed Nozomi Okuhara.
The semi-finals will be played in Wuhan tomorrow, while competition has also been continuing at the European Championships in La Roche sur Yon in France.
Denmark's defending men's champion Jan Ø. Jørgensen booked his place in the last four after a 21-18, 21-11 win over France's Brice Leverdez.
The top seed will meet England's Rajiv Ouseph, who edged out another Dane, Hans-Kristian Vittinghus, 19-21, 21-12, 21-19.
Germany's third seed Marc Zwiebler saw off Belgian Yuhan Tan 21-11, 21-15 and will play Denmark's second seed Viktor Axelsen, the victor over Pablo Abian 21-11, 16-21, 21-13.
In the women's draw, Spain's defending champion Carolina Marín went through after dispatching Finland's Nanna Vainio 21-11, 21-7.
She will meet Denmark's Line Kjærsfeldt, a 21-10, 21-10 win over Bulgaria's Linda Zetchiri.
Denmark will have two players in the last four as unseeded Anna Thea Madsen has also advanced thanks to a 21-19, 21-19 success over Germany's Karin Schnaase.
She will meet Scotland's second seed Kirsty Gilmour, a 21-19, 21-20 win over Spain's Beatriz Corrales.
