Most payments in international trade are made by means of?

Most payments in international trade are made by means of letters of credit. A letter of credit is a document issued by a bank that guarantees the seller will receive payment as long as certain delivery conditions have been met. This provides security for both the buyer and the seller in the transaction, as the buyer can be assured that the goods will be delivered before payment is made, while the seller can be assured that they will receive payment as long as they fulfill their end of the deal. Cash, bills of lading, personal cheques, and traveler's cheques are generally not used for international trade payments as they are not secure or reliable enough for such transactions.
