They prevailed 21-15, 18-21, 21-14 against Jongkolphan Kititharakul and Rawinda Prajongjai to bring the Group A clash to a decider.
The match concluded with the mixed doubles contest, where Dechapol Puavaranukroh and Sapsiree Taerattanachai beat Lee Chun Hei and Chau Hoi Wah 21-16, 21-16 to give Thailand a 3-2 win.
