Don't forget China has banned bitcoin as a payment ways. So there is no way make a merchant accepts bitcoin as a payment method in China, it's just forbidden.
Not sure if this is accurate....
What I do know is, China has a obsession to control it's people... and by linking the Bitcoin address with a persons bank account, would identify him/her to the government. This will be more acceptable for them, if Bitcoin had less annonymity.
It goes against the principles of the general use of Bitcoin, but it enables more people to use it. {So for them, it's a WIN-WIN situation}
It's the same with Coinbase and Circle .... The USA will allow people to use it, just as long as they adhere to all the KYC/AML regulations. {Nothing new here}
