The original source about Chinese ban of ICO and crypto trading is Caxin which is one of the financial media known for close to the government insiders
On 31 August, Caixin first reported China regulator may start regulating ICOs in China.

But the source added that the crackdown targets unauthorized trading at virtual currency exchanges, rather than Bitcoin and the underlying blockchain technology.
Sounds like they are just limiting fiat trades to the BTC/CNY pair. And/or that they will be increasing regulations on exchanges to make sure everything is above board and relatively safe.
