Which gateway to choose for the payment system?

Question

Payment systems

Hello !
Which gateway and/or aggregator can be chosen for the electronic payment system.
chronopay.ru robokassa.ru are not suitable due to their high cost.
The main user base is migrants from China who want to send money back home.
The desire, of course, is for the client to deposit money into the system, and then send it to China. In China, our client's counterparty was able to withdraw money.

Answer 1

That is, if I understand correctly, then in any case I will have to connect to the gateway of Robokassa, Interkassa, Single Wallet or something like that?
