RainFlower Trading Limited is a wholesaler of electronic calculators in Hong Kong. It has been importing goods from a Philippine manufacturer for eight years. The Philippine manufacturer had accepted payments in advance in the past. Recently, because of political turmoil in the Philippines, RainFlower Trading Limited considered that the current trade arrangement was too risky. On the other hand, the Philippine manufacturer would not accept payments on open account and requested to have payment in some form of undertaking by a bank. The manager of RainFlower Trading Limited approaches your bank for help. You are required to:
a) Suggest a method of payment that your bank could assist RainFlower Trading Limited with. Please point out the advantages and disadvantages of your suggestion to the company.
b) Discuss the roles and responsibilities of your bank in the method suggested in part under the relevant rules of the International Chamber of Commerce.
