China's top-seeded duo of Zheng Siwei and Huang Yaqiong eased into the Tokyo 2020 mixed doubles badminton semifinals on Wednesday, after beating world No.4 Praveen Jordan and Melati Daeva Oktavianti of Indonesia 2-0.

World No.1 Zheng and Huang kicked off with an overwhelming start, taking a 21-17 lead. The ­powerful duo continued to ­dominate in the second, snatching a 21-15 win with ease.

Two years ago at the French Open, Zheng and Huang were ­challenged by the Indonesian pair and lost the finals 2-1.

"We have made sufficient preparations in terms of targeted tactics against them, but on the other hand they might not be in their best ­condition due to the pandemic and made some mistakes on court, which offered us chances to win," Zheng said.

Another Chinese pair, Huang Dongping/Wang Yilü, also advanced to the semifinals after defeating South Korea's Seo Seung-jae/Chae Yoo-jung. 

The badminton mixed doubles semifinals will start on Thursday at the Musashino Forest Sport Plaza, with the gold medal match taking place on Friday.
