The People’s Bank of China has issued a new warning to domestic bitcoin exchanges following a “closed-door” meeting with them held on 08 February 2017.

Bloomberg on Wednesday reported that the central bank had a meeting with several domestic bitcoin startups in the country. The fresh warning confirms this news as it says that the PBoC’s inspection team met with BTC Trade, Yunbi, HaoBTC, CHBTC, BTC100, BitBays, Yuanbao, Dahonghuo and Jubi.

In particular, the central bank stated that it has issued specific directives to the firms that they must strictly comply with the anti-money laundering and foreign exchange regulations.

“If there is a bitcoin trading platform in violation of the above requirements, the circumstances are serious. The inspection team will be brought to the relevant departments to be closed down according to law”, the notice read (as quoted by CoinDesk).

The latest development follows the central bank’s meeting with three major bitcoin exchanges – BTCC, Huobi and OKCoin – held in January. Soon after the meeting, these three exchanges decided to implement fee-based trading.

Following yesterday’s meeting, BTC Trade made an announcement on its website that it will also start charge similar fees, effective 13 February 2017.

Bitcoin price slumped when the news on PBoC’s meeting with bitcoin exchanges broke. BTC/USD dropped from 1069 levels to 1025 levels (Bitstamp). The weakness, however, was short-lived and the pair reversed its losses and is currently trading at 1072 levels at the time of writing.
