In other matches, the Chinese shuttlers met few challenges as Tokyo Olympic champion Chen Yufei smashed Aditi Bhatt 21-9, 21-8 in the women's singles as Tokyo Olympic bronze medalist Sindhu of India didn't show up at Vantaa.

Shi Yuqi defeated Sai Praneeth 21-10, 21-10 in the men's singles, while Li Wenmei and Zheng Yu downed Ashwini Ponnappa and Sikki Reddy 21-16, 21-13 in the women's doubles.

In the final match of the mixed doubles, Du Yue along with her 20-year-old partner Feng Yanzhe finished strong against Srikanth Kidambi and Rutaparna Panda 21-9, 21-9.

Du told Xinhua that as a new pair, she and Feng has made apparent progress after team training. She also used her previous Sudirman Cup experience to encourage Feng to relax before taking to the court.

"I remember I was very nervous playing my first Sudirman Cup two years ago," said Du. "I told Feng not to think too much and to play his best. And he did it today. Fantastic!"

Feng struck a confident tone, saying he actually did not know too much about his opponents. "Kidambi is a strong singles player and that's all I know about him. No matter whom I face, I'll try my best. The game proved that we're well prepared and better in counterattack."

The Chinese team has won all the matches by now without losing one single set. The defending champion will encounter Thailand on Wednesday in Group A.
