The tournament is due to conclude on Sunday (January 31), when the World Tour Finals champions will be crowned.

Denmark's Viktor Axelsen, who has won both the Yonex and Toyota Thailand Open so far this month in the Thai capital, is the top seed, but faces a tough group.

Axelsen has beeen drawn in Group A alongside Chinese Taipei's world number two Chou Tien-chen, Malaysia's Lee Zii Jia and Indonesia's Anthony Sinisuka Ginting.

The top two players from the round-robin group will then move onto the semi-finals to play the top two from Group B, which includes Axelsen's compatriot Anders Antonsen, Chinese Taipei's Wang Tzu Wei, India's Kidambi Srikanth and Hong Kong's Angus Ng Ka Long.

Another group of death is in the mixed doubles, with Group A featuring England's Marcus Ellis and Lauren Smith, as well as Thailand's Dechapol Puavaranukroh and Sapsiree Taerattanachai - who have won both tournaments held in Bangkok since the Asian leg of the Tour started earlier this month.

The other two teams are Indonesia's Praveen Jordan and Melati Daeva Oktavianti and South Koreans Seo Seung-jae and Chae Yu-jung.

Group B consists of Mark Lamsfuss and Isabel Herttrich of Germany, France's Thom Gicquel and Delphine Delrue, Indonesia's Hafiz Faizal and Gloria Emanuelle Widjaja and Malaysia's Goh Shoon Huat and Lai Shevon Jemie.
