Thailand kick off their Thomas & Uber Cup campaign on Sunday at Muang Thong Thani's Impact Arena in Nonthaburi.
The women's Uber Cup team face Egypt in their Group C opener while the men's Thomas Cup squad take on South Korea.
The Uber Cup team are led by world No.8 Ratchanok Intanon and No.10 Pornpawee Chochuwong.

This year's star-studded events feature the likes of men's world No.1 Viktor Axelsen, women's top-ranked player Akane Yamaguchi of Japan and former No.1 Tai Tzu-ying of Taiwan.
Tickets for the May 8-15 vents are available at Thai Ticket Major outlets.
