Chinese Taipei and Singapore completed the quarter-final line-up as group play finished at the Badminton Asia Mixed Team Championships today.
Group B was the only pool where the last eight qualifiers had not been decided in Hong Kong, thanks to Singapore's mixed results in their two matches.
They lost 3-2 to Chinese Taipei but beat India by the same score, meaning all three countries had a chance of progressing going into the last fixture at Queen Elizabeth Stadium.
The Taiwanese team were to end Indian interest with another 3-2 victory, meaning they have topped the group with a perfect record.
Their win also sent Singapore through in second place.
Holders Japan beat hosts Hong Kong 3-2 in today's other match.
The sides are the only two in Group A, so were both guaranteed to go through regardless of the result.
In Group C, Indonesia beat Thailand 4-1 to finish top with both countries already through.
It was the same scenario in Group D as China ended at the summit after a 3-2 win over Malaysia, who had also previously qualified.
The quarter-finals tomorrow will see Japan play Malaysia, Indonesia face Singapore, Hong Kong meet Chinese Taipei and China lock horns with Thailand.
Every match features men's and women's singles, men's and women's doubles and mixed doubles and is best-of-five.
Play also continued today at the Badminton World Federation Orléans Masters, a World Tour Super 100 tournament in France.
