Do not treat this like a broken merchant payment. Foreign-card payment flows may work for businesses while person-to-person transfers can fail. Repay with cash, another app, or a later bank transfer.
A friend paid for your Didi, meal, or ticket, and you try to repay them through Alipay. The transfer fails because your account is linked to a foreign card.
Do not assume merchant payments and transfers have the same rules.
Do not assume topping up wallet balance is available to you.
Do not ask strangers to convert money for you.
