Gold Coast, May 28 (IANS): Record champions China and South Korea reached the final of the Sudirman Cup mixed team badminton championship after beating Japan and Thailand respectively in the semi-finals here on Saturday.

China pipped Japan 3-2 in a nail-biting thriller, while South Korea registered an impressive 3-1 victory over Thailand at the Carrara Indoor Sports Stadium.

The spirited Japanese managed to force the contest right down to the wire. But the nerves and skill of Chen Qingchen and Jia Yifan, in the deciding women's doubles match against Misaki Matsumoto and Ayaka Takahashi 21-12 21-19, sealed China's place in Sunday's final, reports Xinhua news agency.

Other players who helped China were singles veteran Lin Dan and the mixed doubles combine of Li Junhui and Liu Yuchen.
