Traveling in Korea, I got a debit card from ICBC. Can I deposit Korean won and use it directly there?

UnionPay cards can be used in Korea. If you want to withdraw money, you have to go to a machine that can use UnionPay cards, but there are not many such machines in Korea. You deposit RMB and get won here, and it is calculated according to the current exchange rate of the bank, which is not cost-effective.

In fact, it is quite reasonable for you to take RMB to Korea to exchange money. My classmates and I both took RMB to exchange money. For example, if you go to Myeongdong, there are money exchange offices everywhere.

Large department stores can generally use UnionPay cards to swipe their cards, which is more expensive than VISA. For example, Myeongdong encourages China people to use UnionPay cards.
