I think the issue is because the person is Thai, and i assume (maybe wrongly) that 'family support' will only be from parent to child or marriage partner, the only way she can transfer money is for educational purposes. If this is not the case, maybe her parents can transfer it? Otherwise if the recipient has an account in Thailand, pay into that and he does transfer himself.
Finally, pay a United States citizen who lives in Thailand the money, and he pays out of his US account. 2 problems, you need trust between the persons transferring money to one another here, and it may be illegal in Thailand.
