Beijing Special Leading Office had a meeting with owners of local cryptocurrency exchanges including OkCoin and Huobi on Sept 15. The Special Office was set up ad hoc last year to manage and control Internet financial risks.
Followed by the meeting, Beijing regulatory authorities issued a document requiring cryptocurrency exchanges registered in Beijing to announce by the end of day on September 15 that no new account registration is allowed and set a deadline past which all trading will cease.
