Hong Kong and Canada were already out of contention for the quarterfinals but both sides ended their campaigns on a high with victories.

China, seeking a record-extending 14th title, and Thailand were already through to the knockout stage but it was the champions who wrapped up Group A with three wins from three.

Wei Yaxin and Feng Yanzhe put China ahead with a 23-21, 21-11 win in their mixed doubles match, and they looked in control after Li Shifeng won the men’s singles rubber 21-18, 17-21, 21-13.

Thailand rallied, and China lost their first match of the competition when women’s world No 2 Wang Zhiyi was defeated 21-19, 13-21, 23-21 by Ratchanok Intanon but China sealed the win with victory in the men’s doubles.

South Korea, four-time winners, finished on maximum points in Group B with a 4-1 victory over Taiwan, who were also already through to the quarterfinals.

After taking a 2-0 lead with wins in the mixed doubles and women’s singles rubbers, South Korea were given a scare when Taiwan’s Lin Chun-Yi won the men’s singles, beating Cho Geon-yeop 21-15, 21-10.

Taiwan then took the first game in the women’s doubles, before Baek Ha-na and Lee So-hee bounced back to defeat Hsieh Pei-shan and Hung En-tzu 17-21, 21-12, 21-12 to put South Korea 3-0 up.

Hong Kong enjoyed a 5-0 sweep of Algeria in Group A where strong singles performances from Saloni Samirbhai Mehta and former men’s world No 6 Angus Ng Ka Lon helped Hong Kong to an unassailable 3-0 lead.

In Group B, Canada stormed past Czech Republic 4-1 with mixed doubles pair Kevin Lee and Eliana Zhang getting them off to the perfect start with a 23-21, 21-18 win over Ondrej Kral and Tereza Svabikova.

Wen Yu Zhang and Brian Yang overcame Petra Maixnerova and Jan Louda, respectively, in their singles matches to give Canada a 3-0 lead.
