Chinese documents suggest that Oppo owns OnePlus

Back in 2013, Oppo’s VP, Pete Lau, resigned in order to start up the OnePlus company which is responsible for the OnePlus One Android handset that runs on CyanogenMod. That being said, it would seem that apart from the fact that Pete Lau used to work for Oppo, there’s really nothing else that ties both companies together, or is there? It seems that OnePlus has one stockholder which turns out to be Oppo, thus suggesting that OnePlus might actually be an Oppo subsidiary.
