In international trade it is almost impossible to match payment

In international trade it is almost impossible to match payment with physical delivery of the goods,which constitutes conflicting problems for trade,since the exporter prefers to get paid before releasing the goods and the importer prefers to gain control over the goods before paying the money.The letter of credit is an effective means to solve these problems.Its objective is to facilitate international payment by means of the credit-worthiness of the bank.
【正确答案】：在国际贸易中,付款同实际交货几乎不可能同时进行,这就构成了贸易中的矛盾,因为出口商喜欢在发货前先得到付款,而进口商则喜欢在付款前便控制货物。信用证是解决这些问题的有效办法它的目的在于通过银行的信誉为国际支付提供便利。
