I have recently applied for SPG American Express, Chase Sapphire Preferred, and Capital One Rewards, all from a China IP address and had no problems. Just used my US address to send the cards to.

I have had many problems with using Paypal from China. Many times they have frozen my account right after I do some activity and I have to call and go through many hassles. I think at this point they have finally put some notes in my account that it is OK to see activity from China. ^
