Cross-border remittance is a business in which personal online banking customers conduct foreign exchange remittances within the prescribed limit to payees who have opened accounts in banks outside mainland China. Cross-border remittance involves both telecommunications fees and handling fees, and the operation is time-consuming. Since cross-border remittance fees generally have a maximum limit, it is recommended to increase the amount of a single remittance within the maximum limit to reduce the number of remittances and save the telegram for each remittance.
