This is stipulated by the Central Bank and Alipay to prevent malicious cash out.

All credit cards cannot be repaid with Alipay balance.

Because in the past, credit cards that were opened for online banking can be recharged to Alipay. If you use the balance to repay, it is equivalent to using a credit card to repay the credit card. This is strictly prohibited by the central bank.

This is the same as when Alipay repays the source card, you can only choose a debit card, but not a credit card.

After credit cards are banned from recharging Alipay in the future, the function of paying back the balance to credit cards will gradually be released.
