With a bank involvement,the exporter looks to the bank for payment
instead of relying upon the ability or willingness of the importer to
pay,but the exporter cannot obtain payment unless he complies with all
pays on behalf of the importer against documents which represent the
goods and give the importer rights to the goods.
Therefore,banks assist in the settlement of international commercial transactions by
providing safeguard for parties involved and ensuring payment to the
exporter if he complies with the terms in the document.These
objectives are accomplished by the use of a document called
documentary letter of credit.

当有银行介入的情形下，出口商可以向银行寻回货款，而非依赖出口商付款的能力或意愿。但是出口商要得到所有出口商应当支付的货款，必须提交证明该货物以及物权已转让给出口商的文件。
因此，对于国际交易，银行可以为该交易的双方提供保障，确保在出口商依相关文件的条款进行索赔时能够拿到货款。我们把这种银行提供的保障方式称为信用证（L/C)。

注：LC是国际贸易常用的一种付款保障方式。出口商会有出货后拿不到应得的货款的风险。LC就是银行推出的为这种风险提供保障的一种方式。
