Yonex retains (as co-sponsors) the Indonesia Open and Indonesia Masters The main/primary sponsor to Indonesia Open is still BCA (Largest Indonesian Banking institution, a subsidiary of Djarum Group) There is no information concerning sponsorship to Indonesia GP Gold Victor were being outbid by YY and Lining. Li-ning made selective bid to Indonesian stars, i.e., Owi/Butet and Mohammad Ahsan They also secure their place by performing a smart bid in supporting PBSI in Thomas/Uber, and Sudirman Cup. Last but not least, Li-Ning supports with official mats and prizes for Indonesian National Tournament. Flypower provides official shuttlecock to Indonesian National Tournament. Note : there is no detail explanation concerning term of contract to each of sponsored players (1 or 2 years)
According to Yoppy Rosimin and Badmintonindonesia.org, the contracts for majority of players is 2 years. Big lost for Victor, their star players like Jonatan Christie, Gideon Markus, Kevin Sanjaya, Tontowi Ahmad, Liliyana Natsir signed by Yonex and Li-Ning.
Probably Victor focused more on bids to the Korean national team? Nice to see Li-Ning get more ground
