Not sure how honest is the transaction now but back in them days, if we need to wire them money, we would just wait for a trusted person who is going back to Vietnam and to give them some money to be given to our folks over there. They would video the transaction and have the recipient accepting the gift.
Can't trust them commie. You send your money, they get a cut and give the scraps to your love ones. They might use extortion tactics and say that if they say anything about the transaction, they would go to jail.
