For your paying Bank(Krung Thai) to remit this remaining funds, they need to send a Swift Message called SWIFT MT 199 to Mizuho Bank in Singapore. This is a SWIFT message with conditions attached. Please see attached the standard SWIFT MT 199 that is propose by Mizuho Bank. I have filled up some of the blanks to assist Buyers to understand(but the actual completion must be done in consultation with Krung Thai Bank because it is Krung Thai Bank that issue the SWIFT MT 199 and SWIFT MT 103. Once the conditions as stated on the SWIFT MT 199 are met, the Release Letter is signed and Krung Thai Bank will send a SWIFT MT 103 to instruct Mizuho Bank to release the funds from the Suspense Account to the Sellers' nominated account(in other words funds are now officially allocated to the Sellers account)
