unionpay line credit card, RMB settlement and RMB repayment;
international lines are swiped, settled in US dollars, repaid in US dollars, or the repayment function of purchasing foreign exchange by credit card is enabled.
Tips
If you take the international route, your consumption will be settled in US dollars (except for all-currency credit cards), so if the consumption amount is not US dollars, there will be an exchange fee between the two currencies (about 1.5% of the transaction amount). If the UnionPay line is swiped or the consumption amount is USD, there will be no settlement fee. If you spend money by credit card overseas, you are advised to choose UnionPay channel.
