Theoretically, any credit card with VISA logo can be associated. I do it for eBay, too. I chose China Merchants Bank because its credit cards are safer and its service is the best in the domestic banking industry. You can go to their website and choose one you like.

Another advantage is that when you need to withdraw foreign currency, you can open a savings account in China Merchants Bank. Paypal now supports China Merchants Bank to withdraw money. You don't have to run two banks.
