The three payment methods generally adopted in international trade settlement are remittance, collection and letter of credit (L/C). Among them, the L/C is the most common and the most valuable financing method. The L/C is a bank credit where the issuing bank is the obligor in the case of importer default, serving as an intermediary as regards payment and transmission of documents. Issuing banks facilitate the financing of trades for both sellers and buyers and thus help bolster international trade. WRCB offers these services to importers.
