I just return from a trip to China and yes I carried a 10yrs China visa to open a bank with Bank of Construction in Guangdong province. No, the bank's front desk refuse it and said they cannot accept foreign passports.
Having a "work" visa is possible though.
Please stop spreading rumours about China when it's not true.
Not sure if things has changed but 1 year ago my brother in law has opened an account in bank of China 中国银行 while he was on a 1 year traveling visa. You may want to try with another bank
I am curious what type of "traveling visa" was that, because a tourist visa don't work for me. Also Chinese government change policies all the time and rollout instantaneously. Whatever works 3-months ago don't mean it works now.
