Payment FAQ:

We have recently received feedback from a number of delegates who are unable to pay their registration fee via the online payment platform.It is possible that banks in many countries have now upgraded their security levels and have increased their audits for international payments. As a result, this has led to a decrease in the success rate of international payments by online payment platforms. Even banks in some countries do not support payments through this platform.

The alternative payment method: Bank transfer

We also accept fee via bank transfer, but there will be a high bank charges. 

Regarding the bank extra fee, we will bear the "Intermediary Bank Fee" and the "Receiving Bank Deposit Fee".
