I can certainly say that this is a tournament in Indonesia there are poldanmig, tolak angin, kompas and djarum (all of them are Indonesian brand (the advert)) and when there are many players like that (near the court), I can say it would be a group fight (and this is decisive battle?) and the only group fight I can remember in Indonesia is Thomas and Uber cup (Thomas would be for men) the rest you can check it especially the opp shirt colour (which country use that shirt colour) and when they fight team China
For one I remember the scene. Secondly it looks like Istore Senayan with they yellow "gate"/tunnel entry and then there's the djarum sponsoring behind. Not to mention the chinese outfits were a topic of discussion http://www.badmintoncentral.com/forums/showthread.php?55279-Thomas-and-Uber-Cup-2008-Photos/page19
