Hold all the monies. Many people want to help, so Cambod perhaps arrange a central point here in Cambodia , ( except for those already in Thailand) for monies to be sent and how and since his sister has provided funds for her till she gets to Thailand, she does not need that $ here.
Once she returns to Thailand have Mint open a Siam Commercial bank account and provide the account #Personally I think it might be a better idea to send her the money when she is in Thailand with her family and they can collect it together. Mint's ticket has been paid by Henning's boss and I have sent her sufficient funds to see her through till Thailand.
than go to the Cambodian commercial bank here ( which i believe is tied with the bank in Thailand as they use the same logo) ) an than u can transfer all the funds to her easily.
Simplifies matters
Just my $05 worth
