Several Bitcoin exchange websites in China are facing suspended bank services.

OKCoin.com, a bitcoin exchange in China, said a branch of China Merchants Bank on Monday suspended services for the website's top-up business following "notices from the superior management department," but services from other banks are normal, according to Tuesday's China Securities Journal.

Huobi.com, another bitcoin exchange in China, said a branch of the Industrial and Commercial Bank of China will suspend its website services on April 18, "following notices from the superior bank."

BtcTrade.com faces a similar situation, with a branch of the Agricultural Bank of China suspending services for the bitcoin exchange website on Tuesday.

Some online Bitcoin exchanges said they will provide services to recharge customer accounts via code scanning or launch U.S. dollar top-up business via overseas platforms in a bid to deal with the new move by the commercial banks.
