Whether it can be used depends on whether the merchants and ATMs in Belarus cover UnionPay. If there is UnionPay's UnionPay logo, it can be used. In addition, judging from the countries and regions where China UnionPay is currently available, Russia has cooperation with UnionPay, so it should be available.

When withdrawing cash overseas through UnionPay and withdrawing local currency from an ATM with the "UnionPay" logo, the cash withdrawal fee is "0.5 of the cash withdrawal amount of 12 yuan", of which the minimum 0.5 of the cash withdrawal amount is ￥2 The maximum RMB limit is ￥50 yuan; and when using a UnionPay card overseas, the local currency of the transaction will be directly converted into RMB at the UnionPay exchange rate and credited into the account, without conversion fees. You only need to pay back RMB when you return home, which is very convenient.
