It’s true. China Banks don’t really issue credit cards to non Chinese.
I have a past experience too.
I bought an apartment and taken a loan with the local bank.
Then they issued me a credit card with a credit limit of only RMB$10,000/-. I tried to apply for another credit card because the limit is too little for me to use when on overseas business trip.
I tried two local banks, China Merchant and Shanghai Pudong Bank. But both rejected me without a reason.
