Chen's victory is also the second from team China this year following Chen Qingchen and Jia Yifan's win in the women's doubles final.

The two 21-year-olds came from behind from one set down and saved two match points in the second set to beat third seed Japanese pair Mayu Matsumoto and Wakana Nagahara 18-21, 22-20, 21-11.

After the game, Chen said: "We're so happy." Jia added: "It's just fantastic to win the title this year and we beat really strong opponents through all the earlier matches - it just gave us so much motivation and confidence for future performances."

Zheng Siwei and Huang Yaqiong took a sweet revenge on their defeat in last year's final as they beat defending champions Yuta Watanabe and Arisa Higashino of Japan 21-17, 22-20, winning China the third title in this tournament.
