At least for android, I'm pretty sure google doesn't control the app store(s) in China. It seems there are many app stores which explains why.

    Tencent MyApp (15.12%)
    360 Mobile Assistant (10.60%)
    Oppo Software Store (9.24%)
    Baidu Mobile Assistant (8.55%)
    Huawei App Market (8.28%)
    MIUI App Store (6.28%)
    Vivo App Store (4.81%)
    PP Assistant (1.98%)
    HiMarket (0.72%)
    Anzhi Market (0.50%)
